1.13 +"""Runs various libyuv tests through valgrind_test.py.
1.14 +
1.15 +This script inherits the chrome_tests.py in Chrome, but allows running any test
1.16 +instead of only the hard-coded ones. It uses the -t cmdline flag to do this, and
1.17 +only supports specifying a single test for each run.
1.18 +
1.19 +Suppression files:
1.20 +The Chrome valgrind directory we use as a DEPS dependency contains the following
1.21 +suppression files:
1.22 + valgrind/memcheck/suppressions.txt
1.23 + valgrind/memcheck/suppressions_mac.txt
1.24 + valgrind/tsan/suppressions.txt
1.25 + valgrind/tsan/suppressions_mac.txt
1.26 + valgrind/tsan/suppressions_win32.txt
1.27 +Since they're referenced from the chrome_tests.py script, we have similar files
1.28 +below the directory of this script. When executing, this script will setup both
1.29 +Chrome's suppression files and our own, so we can easily maintain libyuv
1.30 +specific suppressions in our own files.
