Evan Cheng 44be1a8d66 Enable machine sinking critical edge splitting. e.g. ... define double @foo(double %x, double %y, i1 %c) nounwind { %a = fdiv double %x, 3.2 %z = select i1 %c, double %a, double %y ret double %z } Was: _foo: divsd LCPI0_0(%rip), %xmm0 testb $1, %dil jne LBB0_2 movaps %xmm1, %xmm0 LBB0_2: ret Now: _foo: testb $1, %dil je LBB0_2 divsd LCPI0_0(%rip), %xmm0 ret LBB0_2: movaps %xmm1, %xmm0 ret This avoids the divsd when early exit is taken. rdar://8454886 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@114372 91177308-0d34-0410-b5e6-96231b3b80d8		2010-09-20 22:52:00 +00:00
