[llvm-commits] PATCH: Provide branch weight metadata for instrumentation branches in AddressSanitizer=

[Chandler Carruth]

I have no idea if this heuristic is correct, but I suspect it's pretty
good...

It doesn't really matter what heuristic is used if we insert 'unreachable'
-- that should trump all else, but it seemed simpler to just always set a
flat heavy bias toward the "nothing wrong" direction. Looking at the asm
output, the metadata has the desired effect.
