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