*	[X86] Don't force Nearest-Even rounding for VCVTPS2PH, use MXCSR.	Ahmed Bougacha	2016-02-02	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Officially, we don't acknowledge non-default configurations of MXCSR, as getting there would require usage of the FENV_ACCESS pragma (at least insofar as rounding mode is concerned). We don't support the pragma, so we can assume that the default rounding mode - round to nearest, ties to even - is always used. However, it's inconsistent with the rest of the instruction set, where MXCSR is always effective (unless otherwise specified). Also, it's an unnecessary obstacle to the few brave souls that use fenv.h with LLVM. Avoid the hard-coded rounding mode for fp_to_f16; use MXCSR instead. llvm-svn: 259448
*	[X86] Teach how to custom lower double-to-half conversions under fast-math.	Andrea Di Biagio	2015-02-23	1	-0/+52
	This patch teaches the backend how to expand a double-half conversion into a double-float conversion immediately followed by a float-half conversion. We do this only under fast-math, and if float-half conversions are legal for the target. Added test CodeGen/X86/fastmath-float-half-conversion.ll Differential Revision: http://reviews.llvm.org/D7832 llvm-svn: 230276
