Re: Experimental Address Sanitizer for 4.8 (was Re: How much time left till phase 3?)


It would be nice to have a complete tsan/asan implementation for 4.8
-- IMHO it is one of the major missing (popular) features in gcc, so
the earlier gcc has it the better.

Killing mudlap is a completely different goal which does not have to
be tied to this release.

The question is that since asan/tsan is not enabled by default and its
development won't destablize GCC, is it OK to allow more asan/tsan
related changes to be checked in to 4.8 after stage-1 is closed. They
can be considered as 'bug' fixes.


thanks,

David
