[llvm-commits] [llvm] r125089 - in /llvm/trunk/lib/CodeGen: CriticalAntiDepBreaker.cpp CriticalAntiDepBreaker.h

[Andrew Trick]

Aggressive antidep breaker most likely has similar issues. It's different enough that I can't trivially apply my fix, and I don't have a test case. I also don't know if anyone is using it. I have it on my todo list to look into. Meanwhile, feel free to file a bug!
