# Script that checks that critical functions in TSan runtime have correct number
|
|
# of push/pop/rsp instructions to verify that runtime is efficient enough.
|
|
#
|
|
# This test can fail when backend code generation changes the output for various
|
|
# tsan interceptors. When such a change happens, you can ensure that the
|
|
# performance has not regressed by running the following benchmarks before and
|
|
# after the breaking change to verify that the values in this file are safe to
|
|
# update:

# ./projects/compiler-rt/lib/tsan/tests/rtl/TsanRtlTest-x86_64-Test

# --gtest_also_run_disabled_tests --gtest_filter=DISABLED_BENCH.Mop*
