  "message": "Optimize string escape functions\n\nWhen generating Chromium\u0027s build files, this reduces the number of cycles gn\nuses across all threads from 41,325,733,995 to 38,453,104,830 (-7%) indicated by\ncallgrind.  Runtime is also reduced from 3.45s to 3.43s (-0.6%) measured with\n100 samples.  GN is likely bound more by disk IO and exec_script()\u0027s than CPU\ncycles, so that would explain why runtime reduction is only 0.6%.  But 0.6% is\nstill better than 0%.\n\nBUG\u003dNone\nR\u003dbrettw\n\nChange-Id: Ief145407a0bf3ef00b13ce2532df4ff028f05c89\nReviewed-on: https://gn-review.googlesource.com/c/gn/+/4620\nReviewed-by: Brett Wilson \u003cbrettw@google.com\u003e\nCommit-Queue: Brett Wilson \u003cbrettw@google.com\u003e\n",
