[LLVMdev] More careful treatment of floating point exceptions
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
