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