Generate build files in out/gn and out/gn2. Compare out/gn/toolchain.ninja and out/gn2/toolchain.ninja

Expected: No differences.

Actual:

  command = c$:/src/depot_tools/win_tools-2_7_6_bin/python/bin/python.exe ../../v8/tools/run.py ./bytecode_builtins_list_generator C$:/src/chrome/src/out/gn/gen/v8/builtins-generated/bytecodes-builtins-list.h


vs

  command = c$:/src/depot_tools/win_tools-2_7_6_bin/python/bin/python.exe ../../v8/tools/run.py ./bytecode_builtins_list_generator C$:/src/chrome/src/out/gn2/gen/v8/builtins-generated/bytecodes-builtins-list.h


(see "gn2" vs "gn" in last arg)


See https://chromium-review.googlesource.com/1164536 for how to fix this: Instead of

rebase_path("$target_gen_dir/builtins-generated/bytecodes-builtins-list.h"),

Do

rebase_path("$target_gen_dir/builtins-generated/bytecodes-builtins-list.h", root_build_dir),
