Hi, I am running into this segmentation fault while running a simple function pass on some C benchmarks Program received signal SIGSEGV, Segmentation fault. 0x00000000005c5c00 in AddReachableCodeToWorklist(llvm::BasicBlock*, llvm::SmallPtrSet<llvm::BasicBlock*, 64u>&, llvm::InstCombiner&, llvm::TargetData const*) () What can be the possible reasons of the segmentation fault here? I am trying to figure it out for many days now. I would appreciate any help. Thanks, Naznin -------------...

Hi Sanjay, Thanks, I saw this flag and it's definitely should be considered, but it appeared to me to be static characteristic of target platform. I'm not sure how appropriate it would be to change its value from a front-end. It says "Has", while optional flag would rather say "Uses" meaning that implementation cares about floating point exceptions. Regards, Sergey
