+This directory is here to hold .gni files that contain sets of GN build
+arguments for given configurations.
+
+(Currently this directory is empty because we removed the only thing here, but
+this has come up several times so I'm confident we'll need this again. If this
+directory is still empty by 2017, feel free to delete it. --Brett)
+
+Some projects or bots may have build configurations with specific combinations
+of flags. Rather than making a new global flag for your specific project and
+adding it all over the build to each arg it should affect, you can add a .gni
+file here with the variables.
+
+For example, for project foo you may put in build/args/foo.gni:
+
+ target_os = "android"
+ use_pulseaudio = false
+ use_ozone = true
+ system_libdir = "foo"
+
+Users wanting to build this configuration would run:
+
+ $ gn args out/mybuild
+
+And add the following line to their args for that build directory:
+
+ import("//build/args/foo.gni")
+ # You can set any other args here like normal.
+ is_component_build = false
+
+This way everybody can agree on a set of flags for a project, and their builds
+stay in sync as the flags in foo.gni are modified.

+# #if flags to be expressed naturally. This means you can't directly make a
+# define that generates C++ value of true or false for use in code. If you
+# REALLY need this, you can also use the string "(true)" and "(false)" to
+# prevent the rewriting.
+
+# To check the value of the flag in C code:
+#
+# #include "path/to/here/header_file.h"
+#
+# #if BUILDFLAG(ENABLE_FOO)
+# ...
+# #endif
+#
+# const char kSpamServerUrl[] = BUILDFLAG(SPAM_SERVER_URL);
+#
+# There will no #define called ENABLE_FOO so if you accidentally test for that
+# in an ifdef it will always be negative.
+#
+#
+# Template parameters
+#
+# flags [required, list of strings]
+# Flag values as described above.
+#
+# header [required, string]
+# File name for generated header. By default, this will go in the
+# generated file directory for this target, and you would include it
+# with:
+# #include "<path_to_this_BUILD_file>/<header>"
+#
+# header_dir [optional, string]
+# Override the default location of the generated header. The string will
+# be treated as a subdirectory of the root_gen_dir. For example:
+# header_dir = "foo/bar"
+# Then you can include the header as:
+# #include "foo/bar/baz.h"
+#
+# deps, public_deps, testonly, visibility
+# Normal meaning.
+#
+#
+# Grit defines
+#
+# If one .grd file uses a flag, just add to the grit target:
+#
+# defines = [
+# "enable_doom_melon=$enable_doom_melon",
+# ]
+#
+# If multiple .grd files use it, you'll want to put the defines in a .gni file
+# so it can be shared. Generally this .gni file should include all grit defines
+# for a given module (for some definition of "module"). Then do:
+#
+# defines = ui_grit_defines
+#
+# If you forget to do this, the flag will be implicitly false in the .grd file
+# and those resources won't be compiled. You'll know because the resource
+# #define won't be generated and any code that uses it won't compile. If you
+# see a missing IDS_* string, this is probably the reason.
+#
+#
+# Example
+#
+# buildflag_header("foo_buildflags") {
+# header = "foo_buildflags.h"
+#
+# flags = [
+# # This uses the GN build flag enable_doom_melon as the definition.
+# "ENABLE_DOOM_MELON=$enable_doom_melon",
+#
+# # This force-enables the flag.
+# "ENABLE_SPACE_LASER=true",
+#
+# # This will expand to the quoted C string when used in source code.
+# "SPAM_SERVER_URL=\"http://www.example.com/\"",

+# given tool in the host toolchain and run that (either once or over the list
+# of inputs, depending on the variant).
+#
+# Parameters
+#
+# tool (required)
+# [label] Label of the tool to run. This should be an executable, and
+# this label should not include a toolchain (anything in parens). The
+# host compile of this tool will be used.
+#
+# outputs (required)
+# [list of files] Like the outputs of action (if using "compiled_action",
+# this would be just the list of outputs), or action_foreach (if using
+# "compiled_action_foreach", this would contain source expansions mapping
+# input to output files).
+#
+# args (required)
+# [list of strings] Same meaning as action/action_foreach.
+#
+# inputs (optional)
+# Files the binary takes as input. The step will be re-run whenever any
+# of these change. If inputs is empty, the step will run only when the
+# binary itself changes.
+#
+# visibility
+# deps
+# args (all optional)
+# Same meaning as action/action_foreach.
+#
+#
+# Example of usage:
+#
+# compiled_action("run_my_tool") {

+# outputs = [
+# "$target_gen_dir/mysource.cc",
+# "$target_gen_dir/mysource.h",

+# # The tool takes this input.

+# =============================================================================
+# WHAT IS THIS FILE?
+# =============================================================================
+#
+# This is the master GN build configuration. This file is loaded after the
+# build args (args.gn) for the build directory and after the toplevel ".gn"
+# file (which points to this file as the build configuration).
+#
+# This file will be executed and the resulting context will be used to execute
+# every other file in the build. So variables declared here (that don't start
+# with an underscore) will be implicitly global.
+
+# =============================================================================
+# PLATFORM SELECTION
+# =============================================================================
+#
+# There are two main things to set: "os" and "cpu". The "toolchain" is the name
+# of the GN thing that encodes combinations of these things.
+#
+# Users typically only set the variables "target_os" and "target_cpu" in "gn
+# args", the rest are set up by our build and internal to GN.
+#
+# There are three different types of each of these things: The "host"
+# represents the computer doing the compile and never changes. The "target"
+# represents the main thing we're trying to build. The "current" represents
+# which configuration is currently being defined, which can be either the
+# host, the target, or something completely different (like nacl). GN will
+# run the same build file multiple times for the different required
+# configuration in the same build.
+#
+# This gives the following variables:
+# - host_os, host_cpu, host_toolchain
+# - target_os, target_cpu, default_toolchain
+# - current_os, current_cpu, current_toolchain.
+#
+# Note the default_toolchain isn't symmetrical (you would expect
+# target_toolchain). This is because the "default" toolchain is a GN built-in
+# concept, and "target" is something our build sets up that's symmetrical with
+# its GYP counterpart. Potentially the built-in default_toolchain variable
+# could be renamed in the future.
+#
+# When writing build files, to do something only for the host:
+# if (current_toolchain == host_toolchain) { ...
+
+if (target_os == "") {
+ target_os = host_os
+}
+
+if (target_cpu == "") {
+ if (target_os == "android") {
+ # If we're building for Android, we should assume that we want to
+ # build for ARM by default, not the host_cpu (which is likely x64).
+ # This allows us to not have to specify both target_os and target_cpu
+ # on the command line.
+ target_cpu = "arm"
+ } else {
+ target_cpu = host_cpu
+ }
+}
+
+if (current_cpu == "") {

+}
+if (current_os == "") {

+
+# =============================================================================
+# BUILD FLAGS
+# =============================================================================
+#
+# This block lists input arguments to the build, along with their default
+# values.
+#
+# If a value is specified on the command line, it will overwrite the defaults
+# given in a declare_args block, otherwise the default will be used.
+#
+# YOU SHOULD ALMOST NEVER NEED TO ADD FLAGS TO THIS FILE. GN allows any file in
+# the build to declare build flags. If you need a flag for a single component,
+# you can just declare it in the corresponding BUILD.gn file.
+#
+# - If your feature is a single target, say //components/foo, you can put
+# a declare_args() block in //components/foo/BUILD.gn and use it there.
+# Nobody else in the build needs to see the flag.
+#
+# - Defines based on build variables should be implemented via the generated
+# build flag header system. See //build/buildflag_header.gni. You can put
+# the buildflag_header target in the same file as the build flag itself. You
+# should almost never set "defines" directly.
+#
+# - If your flag toggles a target on and off or toggles between different
+# versions of similar things, write a "group" target that forwards to the
+# right target (or no target) depending on the value of the build flag. This
+# group can be in the same BUILD.gn file as the build flag, and targets can
+# depend unconditionally on the group rather than duplicating flag checks
+# across many targets.
+#
+# - If a semi-random set of build files REALLY needs to know about a define and
+# the above pattern for isolating the build logic in a forwarding group
+# doesn't work, you can put the argument in a .gni file. This should be put
+# in the lowest level of the build that knows about this feature (which should
+# almost always be outside of the //build directory!).
+#
+# Other flag advice:
+#
+# - Use boolean values when possible. If you need a default value that expands
+# to some complex thing in the default case (like the location of the
+# compiler which would be computed by a script), use a default value of -1 or
+# the empty string. Outside of the declare_args block, conditionally expand
+# the default value as necessary.
+#
+# - Use a name like "use_foo" or "is_foo" (whatever is more appropriate for
+# your feature) rather than just "foo".
+#
+# - Write good comments directly above the declaration with no blank line.
+# These comments will appear as documentation in "gn args --list".
+#
+# - Don't call exec_script inside declare_args. This will execute the script
+# even if the value is overridden, which is wasteful. See first bullet.

+ # target that includes javac:processor_classes entries (i.e. there is no
+ # variable here that can be used for this purpose).
+ #
+ # Note also the peculiar use of java_files / java_sources_file. The content
+ # of the java_files list and the java_sources_file file must match exactly.
+ # This rule uses java_files only to list the inputs to the action that
+ # calls the javac.py script, but will pass the list of Java source files
+ # with the '@${java_sources_file}" command-line syntax. Not a problem in
+ # practice since this is only called from java_library_impl() that sets up
+ # the variables properly.
+ #
+ # Variables:
+ # java_files: Optional list of Java source file paths.
+ # srcjar_deps: Optional list of .srcjar dependencies (not file paths).
+ # The corresponding source files they contain will be compiled too.
+ # srcjar_filearg: Optional @FileArg for additional srcjars.
+ # java_sources_file: Optional path to file containing list of Java source
+ # file paths. This must always be provided if java_files is not empty
+ # and must match it exactly.
+ # build_config: Path to the .build_config file of the corresponding
+ # java_library_impl() target. The following entries will be used by this
+ # template: javac:srcjars, deps_info:javac_full_classpath,
+ # deps_info:javac_full_interface_classpath, javac:processor_classpath,
+ # javac:processor_classes
+ # javac_jar_path: Path to the final output .jar file.
+ # javac_args: Optional list of extra arguments to pass to javac.
+ # chromium_code: Whether this corresponds to Chromium-specific sources.
+ # requires_android: True if these sources can only run on Android.
+ # alternative_android_sdk_ijar: Optional path to alternative Android system
+ # interface jar file (android.jar). Ignored it !requires_android.
+ # alternative_android_sdk_ijar_dep: If alternative_android_sdk_ijar is
+ # provided, this should be the dependency target that generates the
+ # alternative .jar file.
+ # additional_jar_files: Optional list of files to copy into the resulting
+ # .jar file (by default, only .class files are put there). Each entry
+ # has the 'srcPath:dstPath' format.
+ # enable_incremental_javac_override: Optional. If provided, determines
+ # whether incremental javac compilation (based on jmake) is enabled.
+ # Otherwise, decision is based on the global enable_incremental_javac
+ # build arg variable.
+ # enable_errorprone: Optional. If True, use the errorprone compiler to
+ # check for error-prone constructs in the language. If not provided,
+ # whether this is enabled depends on chromium_code and the global
+ # use_errorprone_java_compiler variable.
+ # apk_name: Optional APK name. If provided, will tell javac.py to also
+ # generate an .apk.jar.info file under size-info/${apk_name}.apk.jar.info
+ # provider_configurations: Optional list of paths to Java service
+ # provider configuration files [1]. These will be copied under
+ # META-INF/services/ in the final .jar file.
+ # processor_args_javac: List of annotation processor arguments, each one
+ # will be passed to javac as -A<entry>.
+ # deps: Dependencies for the corresponding target.
+ # testonly: Usual meaning (should be True for test-only targets)

+ #
+ # Variables:
+ # type: type of Java target, valid values: 'java_library', 'java_binary',
+ # 'junit_binary', 'java_annotation_processor', and 'android_apk'
+ # main_target_name: optional. If provided, overrides target_name when
+ # creating sub-targets (e.g. "${main_target_name}__build_config") and
+ # some output files (e.g. "${main_target_name}.sources"). Only used
+ # for 'android_apk' types at the moment, where main_target_name will
+ # be the name of the main APK target.
+ # supports_android: Optional. True if target can run on Android.
+ # requires_android: Optional. True if target can only run on Android.
+ # java_files: Optional list of Java source file paths for this target.
+ # srcjar_deps: Optional list of .srcjar targets (not file paths). The Java
+ # source files they contain will also be compiled for this target.
+ # java_sources_file: Optional path to a file which will be written with
+ # the content of java_files. If not provided, the file will be written
+ # under $target_gen_dir/$main_target_name.sources. Ignored if
+ # java_files is empty. If not
+ # jar_path: Optional path to a prebuilt .jar file for this target.
+ # Mutually exclusive with java_files and srcjar_deps.
+ # final_jar_path: Optional path to the final output .jar file (after
+ # processing). If not provided, the output will go under
+ # $root_build_dir/lib.java/
+ # output_name: Optional output name for the final jar path. Ignored if
+ # final_jar_path is provided. Otherwise, used to determine the name
+ # of the final jar. If not provided, the default is to use the same
+ # name as jar_path, if provided, or main_target_name.
+ # dex_path: Optional. Path to the output dex.jar file for this target.
+ # Ignored if !supports_android.
+ # main_class: Main Java class name for 'java_binary', 'junit_binary' and
+ # 'java_annotation_processor' target types. Should not be set for other
+ # ones.
+ # deps: Dependencies for this target.
+ # testonly: True iff target should only be used for tests.
+ # no_build_hooks: Disables bytecode rewriting of asserts and android
+ # resources methods.
+ # chromium_code: Optional. Whether this is Chromium-specific code. If not
+ # provided, this is determined automatically, based on the location of
+ # the source files (i.e. anything under third_party/ is not
+ # Chromium-specific unless it is in a 'chromium' sub-directory).
+ # emma_never_instrument: Optional. If provided, whether to forbid
+ # instrumentation with the Emma coverage processor. If not provided,
+ # this is controlled by the global emma_coverage build arg variable
+ # and only used for non-test Chromium code.
+ # alternative_android_sdk_jar: Optional. Alternative Android system
+ # android.jar to use.
+ # alternative_android_sdk_ijar: Optional alternative Android system
+ # interface jar path (i.e. the alternative_android_sdk_jar file processed
+ # by the ijar tool).
+ # alternative_android_sdk_ijar_dep: Optional. Dependency target that
+ # generates alternative_android_sdk_ijar (if the latter is provided).
+ # annotation_processor_deps: Optional list of dependencies corresponding
+ # to annotation processors used to compile these sources.
+ # input_jars_paths: Optional list of additional .jar file paths, which will
+ # be added to the compile-time classpath when building this target (but
+ # not to the runtime classpath).
+ # classpath_deps: Optional list of additional java library dependencies,
+ # whose .jar files will be added to the compile-time classpath when
+ # building this target (but not to the runtime classpath).
+ # gradle_treat_as_prebuilt: Cause generate_gradle.py to reference this
+ # library via its built .jar rather than including its .java sources.
+ # proguard_enabled: Optional. True to enable ProGuard obfuscation.
+ # proguard_configs: Optional list of additional proguard config file paths.
+ # bypass_platform_checks: Optional. If True, platform checks will not
+ # be performed. They are used to verify that every target with
+ # requires_android only depends on targets that, at least supports_android.
+ # Similarly, if a target has !supports_android, then it cannot depend on
+ # any other target that has requires_android.
+ # include_java_resources: Optional. If True, include Java (not Android)
+ # resources into final .jar file.
+ # android_manifest_for_lint: Optional path to Android manifest to use
+ # if Android linting is enabled. Ignored for 'android_apk' types
+ # (since the value of android_manifest will be used instead).
+ # lint_suppressions_file: Optional lint suppressions input file.
+ # jar_excluded_patterns: Optional list of .class file patterns to exclude
+ # from the final .jar file.
+ # jar_included_patterns: Optional list of .class file patterns to include
+ # in the final .jar file. jar_excluded_patterns take precedence over this.
+ #
+ # For 'android_apk' targets only:
+ #
+ # apk_path: Path to the final APK file.
+ # android_manifest: Path to AndroidManifest.xml file for the APK.
+ # android_manifest_dep: Optional. Dependency target that generates
+ # android_manifest.
+ # apk_under_test: For 'android_apk' targets used to test other APKs,
+ # this is the target name of APK being tested.
+ # incremental_allowed: Optional (default false). True to allow the
+ # generation of incremental APKs ('android_apk' targets only).
+ # incremental_apk_path: If incremental_allowed, path to the incremental
+ # output APK.
+ # incremental_install_json_path: If incremental_allowed, path to the output
+ # incremental install json configuration file.
+ # non_native_packed_relocations: Optional. True if the target Android
+ # system does not support compressed relocations in native shared
+ # libraries.
+ # shared_libraries_runtime_deps_file: Optional. Path to a file listing the
+ # native shared libraries required at runtime by
+ # secondary_abi_shared_libraries_runtime_deps_file:
+ #
+ #
+ # For 'java_binary' and 'junit_binary' targets only. Ignored by others:

+# This template declares a bundle_data target that references an asset
+# catalog so that it is compiled to the asset catalog of the generated
+# bundle.
+#
+# The create_bundle target requires that all asset catalogs are part of an
+# .xcasset bundle. This requirement comes from actool that only receives
+# the path to the .xcasset bundle directory and not to the individual
+# .imageset directories.
+#
+# The requirement is a bit problematic as it prevents compiling only a
+# subset of the asset catakig that are contained in a .xcasset. This template
+# fixes that by instead copying the content of the asset catalog to temporary
+# .xcasset directory (below $root_out_dir) and defining a bundle_data
+# target that refers to those copies (this is efficient as the "copy" is
+# implemented by hardlinking if possible on macOS).
+#
+# Since the create_data target will only refer to the .xcasset directory
+# and additional "action" target that runs a dummy script is defined. It
+# does nothing but pretends to generate the .xcassets directory (while
+# it is really created as a side-effect of the "copy" step). This allows
+# to workaround the check in "gn" that all inputs below $root_out_dir have
+# to be outputs of another target with a public dependency path.
+#
+# This template also ensures that the file are only copied once when the
+# build targets multiple architectures at the same time (aka "fat build").

+# a link-time (as well as build-time) dependency on the framework bundle,
+# depend against "$target_name+link". If only the build-time dependency is
+# required (e.g., for copying into another bundle), then use "$target_name".
+#
+# Arguments
+#
+# output_name:
+# (optional) string, name of the generated framework without the
+# .framework suffix. If omitted, defaults to target_name.
+#
+# public_headers:
+# (optional) list of paths to header file that needs to be copied
+# into the framework bundle Headers subdirectory. If omitted or
+# empty then the Headers subdirectory is not created.
+#
+# sources
+# (optional) list of files. Needs to be defined and non-empty if
+# public_headers is defined and non-empty.
+#
+# enable_code_signing
+# (optional) boolean, control whether code signing is enabled or not,
+# default to ios_enable_code_signing if not defined.
+#
+# This template provides two targets for the resulting framework bundle. The
+# link-time behavior varies depending on which of the two targets below is
+# added as a dependency:
+# - $target_name only adds a build-time dependency. Targets that depend on
+# it will not link against the framework.
+# - $target_name+link adds a build-time and link-time dependency. Targets
+# that depend on it will link against the framework.
+#
+# The build-time-only dependency is used for when a target needs to use the
+# framework either only for resources, or because the target loads it at run-
+# time, via dlopen() or NSBundle. The link-time dependency will cause the
+# dependee to have the framework loaded by dyld at launch.
+#
+# Example of build-time only dependency:
+#
+# framework_bundle("CoreTeleportation") {
+# sources = [ ... ]
+# }
+#
+# bundle_data("core_teleportation_bundle_data") {
+# deps = [ ":CoreTeleportation" ]

+#
+# app_bundle("GoatTeleporter") {
+# sources = [ ... ]
+# deps = [
+# ":core_teleportation_bundle_data",
+# ]
+# }
+#
+# The GoatTeleporter.app will not directly link against
+# CoreTeleportation.framework, but it will be included in the bundle's
+# Frameworks directory.
+#
+# Example of link-time dependency:
+#
+# framework_bundle("CoreTeleportation") {
+# sources = [ ... ]
+# ldflags = [
+# "-install_name",
+# "@executable_path/../Frameworks/$target_name.framework"
+# ]

+# that depend on it will link against the framework.
+#
+# The build-time-only dependency is used for when a target needs to use the
+# framework either only for resources, or because the target loads it at run-
+# time, via dlopen() or NSBundle. The link-time dependency will cause the
+# dependee to have the framework loaded by dyld at launch.
+#
+# Example of build-time only dependency:
+#
+# mac_framework_bundle("CoreTeleportation") {
+# sources = [ ... ]
+# }
+#
+# bundle_data("core_teleportation_bundle_data") {
+# deps = [ ":CoreTeleportation" ]
+# sources = [ "$root_out_dir/CoreTeleportation.framework" ]
+# outputs = [ "{{bundle_contents_dir}}/Frameworks/{{source_file_part}}" ]
+# }
+#
+# app_bundle("GoatTeleporter") {
+# sources = [ ... ]
+# deps = [
+# ":core_teleportation_bundle_data",
+# ]
+# }
+#
+# The GoatTeleporter.app will not directly link against
+# CoreTeleportation.framework, but it will be included in the bundle's
+# Frameworks directory.
+#
+# Example of link-time dependency:
+#
+# mac_framework_bundle("CoreTeleportation") {
+# sources = [ ... ]
+# ldflags = [
+# "-install_name",
+# "@executable_path/../Frameworks/$target_name.framework"
+# ]
+# }
+#
+# bundle_data("core_teleportation_bundle_data") {
+# deps = [ ":CoreTeleportation+link" ]
+# sources = [ "$root_out_dir/CoreTeleportation.framework" ]
+# outputs = [ "{{bundle_contents_dir}}/Frameworks/{{source_file_part}}" ]
+# }
+#
+# app_bundle("GoatTeleporter") {
+# sources = [ ... ]
+# deps = [
+# ":core_teleportation_bundle_data",
+# ]
+# }
+#
+# Note that the framework is still copied to the app's bundle, but dyld will
+# load this library when the app is launched because it uses the "+link"
+# target as a dependency. This also requires that the framework set its

+# Generally you will just want the defaults for the Chrome build. In this case

+# the *_manifest variables defined below to pick and choose only some defaults.

+# Mac and iOS hermetic toolchain instructions
+
+The following is a short explanation of why we use a the hermetic toolchain
+and instructions on how to roll a new toolchain.
+
+## How to roll a new hermetic toolchain.
+
+1. Download a new version of Xcode, and confirm either mac or ios builds
+ properly with this new version.
+
+2. Run the following command:
+
+ ```
+ src/build/package_mac_toolchain.py /path/to/Xcode.app/ [ios|mac]
+ ```
+
+ The script will create a subset of the toolchain necessary for a build, and
+ upload them to be used by hermetic builds.
+
+ If for some reason this toolchain version has already been uploaded, the
+ script will ask if we should create sub revision. This can be necessary when
+ the package script has been updated to compress additional files.
+
+2. Create a CL with updated [MAC|IOS]_TOOLCHAIN_VERSION and _SUB_REVISION in
+ src/build/mac_toolchain.py with the version created by the previous command.
+
+3. Run the CL through the trybots to confirm the roll works.
+
+## Why we use a hermetic toolchain.
+
+Building Chrome Mac currently requires many binaries that come bundled with
+Xcode, as well the macOS and iphoneOS SDK [also bundled with Xcode]. Note that
+Chrome ships its own version of clang [compiler], but is dependent on Xcode
+for these other binaries.
+
+Chrome should be built against the latest SDK available, but historically,
+updating the SDK has been nontrivially difficult. Additionally, bot system
+installs can range from Xcode 5 on some bots, to the latest and
+greatest. Using a hermetic toolchain has two main benefits:
+
+1. Build Chrome with a well-defined toolchain [rather than whatever happens to
+be installed on the machine].
+
+2. Easily roll/update the toolchain.

+"""Converts a given gypi file to a python scope and writes the result to stdout.
+
+USING THIS SCRIPT IN CHROMIUM
+
+Forking Python to run this script in the middle of GN is slow, especially on
+Windows, and it makes both the GYP and GN files harder to follow. You can't
+use "git grep" to find files in the GN build any more, and tracking everything
+in GYP down requires a level of indirection. Any calls will have to be removed
+and cleaned up once the GYP-to-GN transition is complete.
+
+As a result, we only use this script when the list of files is large and
+frequently-changing. In these cases, having one canonical list outweights the
+downsides.
+
+As of this writing, the GN build is basically complete. It's likely that all
+large and frequently changing targets where this is appropriate use this
+mechanism already. And since we hope to turn down the GYP build soon, the time
+horizon is also relatively short. As a result, it is likely that no additional
+uses of this script should every be added to the build. During this later part
+of the transition period, we should be focusing more and more on the absolute
+readability of the GN build.
+
+
+HOW TO USE
+
+It is assumed that the file contains a toplevel dictionary, and this script
+will return that dictionary as a GN "scope" (see example below). This script
+does not know anything about GYP and it will not expand variables or execute
+conditions.
+
+It will strip conditions blocks.
+
+A variables block at the top level will be flattened so that the variables
+appear in the root dictionary. This way they can be returned to the GN code.
+
+Say your_file.gypi looked like this:
+ {
+ 'sources': [ 'a.cc', 'b.cc' ],
+ 'defines': [ 'ENABLE_DOOM_MELON' ],
+ }
+
+You would call it like this:
+ gypi_values = exec_script("//build/gypi_to_gn.py",
+ [ rebase_path("your_file.gypi") ],
+ "scope",
+ [ "your_file.gypi" ])
+
+Notes:
+ - The rebase_path call converts the gypi file from being relative to the
+ current build file to being system absolute for calling the script, which
+ will have a different current directory than this file.
+
+ - The "scope" parameter tells GN to interpret the result as a series of GN
+ variable assignments.
+
+ - The last file argument to exec_script tells GN that the given file is a
+ dependency of the build so Ninja can automatically re-run GN if the file
+ changes.
+
+Read the values into a target like this:
+ component("mycomponent") {
+ sources = gypi_values.sources
+ defines = gypi_values.defines
+ }
+
+Sometimes your .gypi file will include paths relative to a different
+directory than the current .gn file. In this case, you can rebase them to
+be relative to the current directory.
+ sources = rebase_path(gypi_values.sources, ".",
+ "//path/gypi/input/values/are/relative/to")
+
+This script will tolerate a 'variables' in the toplevel dictionary or not. If
+the toplevel dictionary just contains one item called 'variables', it will be
+collapsed away and the result will be the contents of that dictinoary. Some
+.gypi files are written with or without this, depending on how they expect to
+be embedded into a .gyp file.
+
+This script also has the ability to replace certain substrings in the input.
+Generally this is used to emulate GYP variable expansion. If you passed the
+argument "--replace=<(foo)=bar" then all instances of "<(foo)" in strings in
+the input will be replaced with "bar":
+
+ gypi_values = exec_script("//build/gypi_to_gn.py",
+ [ rebase_path("your_file.gypi"),
+ "--replace=<(foo)=bar"],
+ "scope",
+ [ "your_file.gypi" ])

+You can run programs inside of the chroot by invoking the
+"/usr/local/bin/${target%bit}" command.
+
+This command can be used with arguments, in order to just run a single
+program inside of the chroot environment (e.g. "${target%bit} make chrome")
+or without arguments, in order to run an interactive shell session inside
+of the chroot environment.
+
+If you need to run things as "root", you can use "sudo" (e.g. try
+"sudo ${target%bit} apt-get update").
+
+Your home directory is shared between the host and the chroot. But I
+configured "${HOME}/chroot" to be private to the chroot environment.
+You can use it for files that need to differ between environments. This
+would be a good place to store binaries that you have built from your
+source files.
+
+For Chrome, this probably means you want to make your "out" directory a
+symbolic link that points somewhere inside of "${HOME}/chroot".
+
+You still need to run "gclient runhooks" whenever you switch from building

+Internal property sheets:
+ essential.vsprops
+ Contains the common settings used throughout the projects. Is included by either ..\debug.vsprops or ..\release.vsprops, so in general, it is not included directly.
+
+ release_defaults.vsprops
+ Included by ..\release.vsprops. Its settings are overriden by release_impl$(CHROME_BUILD_TYPE).vsprops. Uses the default VS setting which is "Maximize Speed". Results in relatively fast build with reasonable optimization level but without whole program optimization to reduce build time.
+
+ release_impl.vsprops
+ Included by ..\release.vsprops by default when CHROME_BUILD_TYPE is undefined. Includes release_defaults.vsprops.
+
+ release_impl_checksenabled.vsprops
+ Included by ..\release.vsprops when CHROME_BUILD_TYPE=_checksenabled. Matches what release_defaults.vsprops does, but doesn't actually inherit from it as we couldn't quite get that working. The only difference is that _DEBUG is set instead of NDEBUG. Used for keeping debug checks enabled with a build that is fast enough to dogfood with.
+
+ release_impl_official.vsprops
+ Included by ..\release.vsprops when CHROME_BUILD_TYPE=_official. Includes release_defaults.vsprops. Enables Whole Program Optimizations (WPO), which doubles the build time. Results in much more optimized build. Uses "Full Optimization" and "Flavor small code".
+
+ release_impl_pgo_instrument.vsprops
+ Included by ..\release.vsprops when CHROME_BUILD_TYPE=_pgo_instrument. Includes release_defaults.vsprops. Enables Profile Guided Optimization (PGO) instrumentation (first pass). Uses "Full Optimization" and "Flavor small code".
+
+ release_impl_pgo_optimize.vsprops
+ Included by ..\release.vsprops when CHROME_BUILD_TYPE=_pgo_optimize. Includes release_defaults.vsprops. Enables Profile Guided Optimization (PGO) optimization (second pass). Uses "Full Optimization" and "Flavor small code".
+
+ release_impl_purify.vsprops
+ Included by ..\release.vsprops when CHROME_BUILD_TYPE=_purify. Includes release_defaults.vsprops. Disables optimizations. Used with Purify to test without debug tools and without optimization; i.e. NDEBUG is defined but the compiler doesn't optimize the binary.

+This script runs every build as the first hook (See DEPS). If it detects that

+
+A landmine is tripped when a builder checks out a different revision, and the
+diff between the new landmines and the old ones is non-null. At this point, the
+build is clobbered.
+
+Before adding or changing a landmine consider the consequences of doing so.
+Doing so will wipe out every output directory on every Chrome developer's
+machine. This can be particularly problematic on Windows where the directory
+deletion may well fail (locked files, command prompt in the directory, etc.),
+and generated .sln and .vcxproj files will be deleted.
+
+This output directory deletion will be repated when going back and forth across
+the change that added the landmine, adding to the cost. There are usually less

+"""Install Debian sysroots for building chromium.
+"""
+
+# The sysroot is needed to ensure that binaries that get built will run on
+# the oldest stable version of Debian that we currently support.
+# This script can be run manually but is more often run as part of gclient
+# hooks. When run from hooks this script is a no-op on non-linux platforms.
+
+# The sysroot image could be constructed from scratch based on the current state
+# of the Debian archive but for consistency we use a pre-built root image (we
+# don't want upstream changes to Debian to effect the chromium build until we
+# choose to pull them in). The images will normally need to be rebuilt every
+# time chrome's build dependencies are changed but should also be updated
+# periodically to include upstream security fixes from Debian.

+This directory contains files that make it possible for Linux
+distributions to build Chromium using system libraries and exclude the
+source code for Chromium's bundled copies of system libraries in a
+consistent manner. Nothing here is used in normal developer builds.
+
+
+For more info on the Linux distros' philosophy on bundling system
+libraries and why this exists, please read the following:
+
+ - https://fedoraproject.org/wiki/Packaging:No_Bundled_Libraries
+ - https://wiki.gentoo.org/wiki/Why_not_bundle_dependencies
+ - http://www.debian.org/doc/debian-policy/ch-source.html#s-embeddedfiles
+
+For more Chromium-specific context please read
+http://spot.livejournal.com/312320.html .
+
+Additional resources which might provide even more context:
+
+ - http://events.linuxfoundation.org/sites/events/files/slides/LinuxCon%202014%20Slides_0.pdf
+ - https://lwn.net/Articles/619158/
+
+
+This directory is provided in the source tree so one can follow the
+above guidelines without having to download additional tools and worry
+about having the right version of the tool. It is a compromise solution
+which takes into account Chromium developers who want to avoid the
+perceived burden of more conditional code in build files, and
+expectations of Open Source community, where using system-provided
+libraries is the norm.
+
+Usage:
+
+1. remove_bundled_libraries.py <preserved-directories>
+
+ For example: remove_bundled_libraries.py third_party/mesa
+
+ The script scans sources looking for third_party directories.
+ Everything that is not explicitly preserved is removed (except for
+ GYP/GN build files), and the script fails if any directory passed on
+ command line does not exist (to ensure list is kept up to date).
+
+ This is intended to be used on source code extracted from a tarball,
+ not on a git repository.
+
+ NOTE: by default this will not remove anything (for safety). Pass
+ the --do-remove flag to actually remove files.
+
+2. replace_gn_files.py --system-libraries lib...
+
+ This swaps out a normal library GN build file that is intended for
+ use with a bundled library for a build file that is set up to use
+ the system library. While some build files have use_system_libfoo
+ build flags, using unbundled build files has the advantage that Linux
+ distros can build Chromium without having to specify many additional
+ build flags.
+
+ For example: replace_gn_files.py --system-libraries libxml

+# This file is meant to be included into an target to create a unittest that
+# invokes a set of no-compile tests. A no-compile test is a test that asserts
+# a particular construct will not compile.
+#
+# Also see:
+# http://dev.chromium.org/developers/testing/no-compile-tests
+#
+# To use this, create a gyp target with the following form:
+#
+# import("//build/nocompile.gni")
+# nocompile_test("my_module_nc_unittests") {
+# sources = [
+# 'nc_testset_1.nc',
+# 'nc_testset_2.nc',
+# ]
+# }
+#
+# The .nc files are C++ files that contain code we wish to assert will not
+# compile. Each individual test case in the file should be put in its own
+# #ifdef section. The expected output should be appended with a C++-style
+# comment that has a python list of regular expressions. This will likely
+# be greater than 80-characters. Giving a solid expected output test is
+# important so that random compile failures do not cause the test to pass.
+#
+# Example .nc file:
+#
+# #if defined(TEST_NEEDS_SEMICOLON) // [r"expected ',' or ';' at end of input"]
+#
+# int a = 1
+#
+# #elif defined(TEST_NEEDS_CAST) // [r"invalid conversion from 'void*' to 'char*'"]
+#
+# void* a = NULL;
+# char* b = a;
+#
+# #endif
+#
+# If we needed disable TEST_NEEDS_SEMICOLON, then change the define to:
+#
+# DISABLE_TEST_NEEDS_SEMICOLON
+# TEST_NEEDS_CAST
+#
+# The lines above are parsed by a regexp so avoid getting creative with the
+# formatting or ifdef logic; it will likely just not work.
+#
+# Implementation notes:
+# The .nc files are actually processed by a python script which executes the
+# compiler and generates a .cc file that is empty on success, or will have a
+# series of #error lines on failure, and a set of trivially passing gunit
+# TEST() functions on success. This allows us to fail at the compile step when
+# something goes wrong, and know during the unittest run that the test was at
+# least processed when things go right.

+# Overview
+
+This directory contains files that make it possible for Linux
+distributions to build Chromium using system toolchain.
+
+For more info on established way such builds are configured,
+please read the following:
+
+ - https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
+
+Why do distros want CFLAGS, LDFLAGS, etc? Please read the following
+for some examples. This is not an exhaustive list.
+
+ - https://wiki.debian.org/Hardening
+ - https://wiki.ubuntu.com/DistCompilerFlags
+ - https://fedoraproject.org/wiki/Changes/Harden_All_Packages
+ - https://fedoraproject.org/wiki/Changes/Modernise_GCC_Flags
+ - https://fedoraproject.org/wiki/Packaging:Guidelines#Compiler_flags
+ - https://blog.flameeyes.eu/2010/09/are-we-done-with-ldflags/
+ - https://blog.flameeyes.eu/2008/08/flags-and-flags/
+
+# Usage
+
+Add the following to GN args:
+
+```
+custom_toolchain="//build/toolchain/linux/unbundle:default"
+host_toolchain="//build/toolchain/linux/unbundle:default"
+```
+
+See [more docs on GN](https://chromium.googlesource.com/chromium/src/+/master/tools/gn/docs/quick_start.md).
+
+To cross-compile (not fully tested), add the following:
+
+```
+host_toolchain="//build/toolchain/linux/unbundle:host"
+v8_snapshot_toolchain="//build/toolchain/linux/unbundle:host"
+```
+
+Note: when cross-compiling for a 32-bit target, a matching 32-bit toolchain
+may be needed.

+# rc
+
+This contains a cross-platform reimplementation of rc.exe.
+
+This exists mainly to compile .rc files on non-Windows hosts for cross builds.
+However, it also runs on Windows for two reasons:
+
+1. To compare the output of Microsoft's rc.exe and the reimplementation and to
+ check that they produce bitwise identical output.
+2. The reimplementation supports printing resource files in /showIncludes
+ output, which helps getting build dependencies right.
+
+The resource compiler consists of two parts:
+
+1. A python script rc.py that serves as the driver. It does unicode
+ conversions, runs the input through the preprocessor, and then calls the
+ actual resource compiler.
+2. The resource compiler, a C++ binary obtained via sha1 files from Google
+ Storage. The binary's code currenty lives at
+ https://github.com/nico/hack/tree/master/res, even though work is (slowly)
+ underway to upstream it into LLVM.
+
+To update the rc binary, run `upload_rc_binaries.sh` in this directory, on a
+Mac.
+
+rc isn't built from source as part of the regular chrome build because
+it's needed in a gn toolchain tool, and these currently cannot have deps.
+Alternatively, gn could be taught about deps on tools, or rc invocations could
+be not a tool but a template like e.g. yasm invocations (which can have deps),
+then the prebuilt binaries wouldn't be needed.

+======================================================================
+
+Let's make a story. Add zero+ sentences for every commit:
+
+CHÄPTER 1:
+It was a dark and blinky night; the rain fell in torrents -- except at
+occasional intervals, when it was checked by a violent gust of wind which
+swept up the streets (for it is in London that our scene lies), rattling along
+the housetops, and fiercely agitating the scanty flame of the lamps that
+struggled against the elements. A hooded figure emerged.
+
+It was a Domo-Kun.
+
+"What took you so long?", inquired his wife.
+
+Silence. Oblivious to his silence, she continued, "Did Mr. Usagi enjoy the
+waffles you brought him?" "You know him, he's not one to forego a waffle,
+no matter how burnt," he snickered.
+
+The pause was filled with the sound of compile errors.
+
+CHAPTER 2:
+The jelly was as dark as night, and just as runny.
+The Domo-Kun shuddered, remembering the way Mr. Usagi had speared his waffles
+with his fork, watching the runny jelly spread and pool across his plate,
+like the blood of a dying fawn. "It reminds me of that time --" he started, as
+his wife cut in quickly: "-- please. I can't bear to hear it.". A flury of
+images coming from the past flowed through his mind.
+
+"You recall what happened on Mulholland drive?" The ceiling fan rotated slowly
+overhead, barely disturbing the thick cigarette smoke. No doubt was left about
+when the fan was last cleaned.
+
+There was a poignant pause.
+
+CHAPTER 3:
+Mr. Usagi felt that something wasn't right. Shortly after the Domo-Kun left he
+began feeling sick. He thought out loud to himself, "No, he wouldn't have done
+that to me." He considered that perhaps he shouldn't have pushed so hard.
+Perhaps he shouldn't have been so cold and sarcastic, after the unimaginable
+horror that had occurred just the week before.
+
+Next time, there won't be any sushi. Why sushi with waffles anyway? It's like
+adorning breakfast cereal with halibut -- shameful.
+
+CHAPTER 4:
+The taste of stale sushi in his mouth the next morning was unbearable. He
+wondered where the sushi came from as he attempted to wash the taste away with
+a bottle of 3000¥ sake. He tries to recall the cook's face. Green? Probably.
+
+CHAPTER 5:
+Many tears later, Mr. Usagi would laugh at the memory of the earnest,
+well-intentioned Domo-Kun. Another day in the life. That is when he realized that
+life goes on.

+Reeccciiiipppppeeeeeesssssss!!!!!!!!!
+PEOPLE SAY "FAILURE IS NOT AN OPTION", BUT FAILURE IS ALWAYS AN OPTION.
+WHAT GOES UP MUST HAVE A NON-ZERO VELOCITY

+The first time Yossarian saw the chaplain, he fell madly in love with him.

+*

+Give not thyself up, then, to fire, lest it invert thee, deaden thee; as for
+the time it did me. There is a wisdom that is woe; but there is a woe that is
+madness. And there is a Catskill eagle in some souls that can alike dive down
+into the blackest gorges, and soar out of them again and become invisible in
+the sunny spaces. And even if he for ever flies within the gorge, that gorge
+is in the mountains; so that even in his lowest swoop the mountain eagle is
+still higher than other birds upon the plain, even though they soar.

+I'm here to commit lines and drop rhymes

+This is a line to test and try uploading a cl.
+
+And lo, in the year 2014, there was verily an attempt to upgrade to GCC 4.8 on
+the Android bots, and it was good. Except on one bot, where it was bad. And
+lo, the change was reverted, and GCC went back to 4.6, where code is slower
+and less optimized. And verily did it break the build, because artifacts had
+been created with 4.8, and alignment was no longer the same, and a great
+sadness descended upon the Android GN buildbot, and it did refuseth to build
+any more. But the sheriffs thought to themselves: Placebo! Let us clobber the
+bot, and perhaps it will rebuild with GCC 4.6, which hath worked for many many
+seasons. And so they modified the whitespace file with these immortal lines,
+and visited it upon the bots, that great destruction might be wrought upon
+their outdated binaries. In clobberus, veritas.
+
+As the git approaches, light begins to shine through the SCM thrice again...
+However, the git, is, after all, quite stupid.
+
+Suddenly Domo-Kun found itself in a room filled with dazzling mirrors. As
+Domo-Kun looked around, it realized that some of the mirrors were actually but
+pale reflections of true reality.
+
+A herd of wild gits appears! Time for CQ :D
+And one more for sizes.py...
+
+What's an overmarketed dietary supplement expressing sadness, relief,
+tiredness, or a similar feeling.? Ah-Sigh-ee.
+
+It was love at first sight. The moment Yossarian first laid eyes on the chaplain, he fell madly in love with him.
+
+Cool whitespace change for git-cl land
+
+Oh god the bots are red! I'm blind! Mmmm, cronuts.
+
+If you stand on your head, you will get footprints in your hair.
+
+sigh
+sigher
+pick up cls
+
+In the BUILD we trust.
+^_^
+
+In the masters we don't.
+In the tryservers, we don't either.
+In the CQ sometimes.

+My sandwiches are like my children: I love them all.
+No, really, I couldn't eat another bit.
+When I hunger I think of you, and a pastrami sandwich.
+Do make a terrible mistake every once in a while.
+I just made two.
+Mistakes are the best sometimes.
