# a06ad186	15-Jan-2019	Roman Lebedev <[email protected]>	[compiler-rt][UBSan] Sanitization for alignment assumptions. Summary: This is the compiler-rt part. The clang part is D54589.

This is a second commit, the original one was r351106, which was mass-reverted in r351159 because 2 compiler-rt tests were failing. Now, i have fundamentally changed the testing approach: i malloc a few bytes, intentionally mis-align the pointer (increment it by one), and check that. Also, i have decreased the expected alignment. This hopefully should be enough to pacify all the bots. If not, i guess i might just drop the two 'bad' tests.

Once again, just like with r338296, these tests seem to only have failed sanitizer-x86_64-linux-android, so let's just disable them, since that seems like the pre-established practice here.. To be noted, they failed on some configs there, but not all, so it is not XFAIL. llvm-svn: 351119 show more ...
