Chris Lattner 1f46cc2345 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. llvm-svn: 47660		2008-02-27 05:57:41 +00:00
