"""\
Convenience wrapper for compiling V8 with gn/ninja and running tests.
Sets up build output directories if they don't exist.
Produces simulator builds for non-Intel target architectures.
Uses Goma by default if it is detected (at output directory setup time).
Expects to be run from the root of a V8 checkout.
Usage:
gm.py [<arch>].[<mode>[-<suffix>]].[<target>] [testname...]
All arguments are optional. Most combinations should work, e.g.:
gm.py ia32.debug x64.release x64.release-my-custom-opts d8
gm.py android_arm.release.check
gm.py x64 mjsunit/foo cctest/test-bar/*
