[LLVMdev] ubsan suppression

[Jonas Wagner]

Hi,

is there a way to suppress specific undefined sanitizer warnings, in

You can do so globally by selecting individual checks. Instead of
-fsanitize=undefined, you can use -fsanitize=alignment,bool,bounds,enum,...
(see the manual <http://clang.llvm.org/docs/UsersManual.html> for a list).

I'm not aware of a possibility to do this with blacklist files or at finer
granularity, though.

Best,
Jonas
