Floating point semantic modes
...to their command line defined settings.
I don't think this pragma should have any effect on contract, support_math_errno, no_honor_nans, or no_honor_infinities.
STDC FP_CONTRACT {ON|OFF|DEFAULT}
This pragma controls the contract FP semantic mode. No other FP semantic modes are effected.
float_control ({precise|except}, {on|off}[, push])
float_control (pop)
Patch in progress. These are tricky.
I think they should have the following effects:
float_control (precise, on[, push])
contract { on }
denormal_fp_math { IEEE }
denormal_fp32_math { IEEE }
no_signed_zeros { off }

EuroLLVM Numerics issues
All: There will be a BoF talk at the EuroLLVM conference regarding Numerics (FMF and module flags which control fp behavior and optimization).
Even if you are not going to be in attendance, please reply to this thread as we are collecting open issues and ideas for future direction in all layers of LLVM for which optimizations are controlled by numerics flags. Please read over the numerics blog
