|
|
# 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.
