Chris Lattner af723b9ae4 Add target-specific dag combines for FAND(x,0) and FOR(x,0). This allows ... us to compile: double test(double X) { return copysign(0.0, X); } into: _test: andpd LCPI1_0(%rip), %xmm0 ret instead of: _test: pxor %xmm1, %xmm1 andpd LCPI1_0(%rip), %xmm1 movapd %xmm0, %xmm2 andpd LCPI1_1(%rip), %xmm2 movapd %xmm1, %xmm0 orpd %xmm2, %xmm0 ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46344 91177308-0d34-0410-b5e6-96231b3b80d8		2008-01-25 05:46:26 +00:00
