when we know the signbit of an input to uint_to_fp is zero, change it to sint_to_fp on targets where that is cheaper (and visaversa of course). This allows us to compile uint_to_fp to: _test: movl 4(%esp), %eax shrl $23, %eax cvtsi2ss %eax, %xmm0 movl 8(%esp), %eax movss %xmm0, (%eax) ret instead of: .align 3 LCPI1_0: ## double .long 0 ## double least significant word 4.5036e+15 .long 1127219200 ## double most significant word 4.5036e+15 .text .align 4,0x90 .globl _test _test: subl $12, %esp movl 16(%esp), %eax shrl $23, %eax movl %eax, (%esp) movl $1127219200, 4(%esp) movsd (%esp), %xmm0 subsd LCPI1_0, %xmm0 cvtsd2ss %xmm0, %xmm0 movl 20(%esp), %eax movss %xmm0, (%eax) addl $12, %esp ret llvm-svn: 52747
