Benjamin Kramer	01b75cc0f2	Test case hygiene. llvm-svn: 176772	2013-03-09 18:25:40 +00:00
NAKAMURA Takumi	68d1700eae	test/CodeGen/X86/fp-fast.ll: Add +avx. llvm-svn: 167207	2012-11-01 02:13:45 +00:00
Owen Anderson	b351c8d692	Add a few more simple fast-math constant propagations and cancellations. llvm-svn: 167200	2012-11-01 02:00:53 +00:00
NAKAMURA Takumi	d35a4ff88b	llvm/test/CodeGen/X86/fp-fast.ll: Suppress FMA4 on AMD Bulldozer host, corresponding to r162999. llvm-svn: 163041	2012-09-01 00:26:28 +00:00
Owen Anderson	d1545e3715	Try to make this test more generic to unbreak buildbots. llvm-svn: 162958	2012-08-30 23:51:20 +00:00
Owen Anderson	cc61f87cf7	Teach the DAG combiner to turn chains of FADDs (x+x+x+x+...) into FMULs by constants. This is only enabled in unsafe FP math mode, since it does not preserve rounding effects for all such constants. llvm-svn: 162956	2012-08-30 23:35:16 +00:00
