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

[X86] Remove the suffix on vcvt[u]si2ss/sd register variants in assembly printing. We require d/q suffixes on the memory form of these instructions to disambiguate the memory size. We don't require it on the register forms, but need to support parsing both with and without it. Previously we always printed the d/q suffix on the register forms, but it's redundant and inconsistent with gcc and objdump. After this patch we should support the d/q for parsing, but not print it when its unneeded. llvm-svn: 360085
