1# Testing rules for AddressSanitizer.
2#
3# These are broken into two buckets. One set of tests directly interacts with
4# the runtime library and checks its functionality. These are the
5# no-instrumentation tests.
6#
7# Another group of tests relies upon the ability to compile the test with
8# address sanitizer instrumentation pass. These tests form "integration" tests
9# and have some elements of version skew -- they test the *host* compiler's
10# instrumentation against the just-built runtime library.
