Jakob Stoklund Olesen	b6b474a8c9	Add Intel legalization for fmin and fmax. The native x86_fmin and x86_fmax instructions don't behave correctly for NaN inputs and when comparing +0.0 to -0.0, so we need separate branches for those cases.	2017-09-27 12:55:34 -07:00
Jakob Stoklund Olesen	7fb6159a85	Add Intel encodings for the fcmp instruction. Not all floating point condition codes are directly supported by the ucimiss/ucomisd instructions. Some inequalities need to be reversed and eq+ne require two separate tests.	2017-09-26 11:17:32 -07:00
Jakob Stoklund Olesen	54534e2147	Add Intel legalization for division and multiplication. These operations need custom legalization in order to use Intel's div and idiv instructions.	2017-07-28 16:41:59 -07:00

Add Intel legalization for fmin and fmax.

The native x86_fmin and x86_fmax instructions don't behave correctly for
NaN inputs and when comparing +0.0 to -0.0, so we need separate branches
for those cases.

Not all floating point condition codes are directly supported by the
ucimiss/ucomisd instructions. Some inequalities need to be reversed and
eq+ne require two separate tests.
