Chris Lattner b09916bdfb Make X86TargetLowering::LowerSINT_TO_FP return without creating a dead ... stack slot and store if the SINT_TO_FP is actually legal. This allows us to compile: double a(double b) {return (unsigned)b;} to: _a: cvttsd2siq %xmm0, %rax movl %eax, %eax cvtsi2sdq %rax, %xmm0 ret instead of: _a: subq $8, %rsp cvttsd2siq %xmm0, %rax movl %eax, %eax cvtsi2sdq %rax, %xmm0 addq $8, %rsp ret crazy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47660 91177308-0d34-0410-b5e6-96231b3b80d8		2008-02-27 05:57:41 +00:00
