Copy Valgrind scripts from Chromium's tools/ to unblock rolling: valgrind/chrome_tests.bat valgrind/chrome_tests.py valgrind/chrome_tests.sh valgrind/common.py valgrind/gdb_helper.py valgrind/locate_valgrind.sh valgrind/memcheck_analyze.py valgrind/valgrind.gni valgrind/valgrind.sh valgrind/valgrind_test.py valgrind_test.py was stripped of its Mac and Dr Memory specific parts, which we don't use. There's still more cleanup to do, tracked in bugs.webrc.org/7849.

# This is a small script for manually launching valgrind, along with passing
|
|
# it the suppression file, and some helpful arguments (automatically attaching
|
|
# the debugger on failures, etc). Run it from your repo root, something like:
|
|
# $ sh ./tools/valgrind/valgrind.sh ./out/Debug/chrome
|
|
#
|
|
# This is mostly intended for running the chrome browser interactively.
|
|
# To run unit tests, you probably want to run chrome_tests.sh instead.
|
|
# That's the script used by the valgrind buildbot.
