The current sequence movl %ecx, 8(%esp) movl %edx, 12(%esp) fildll 8(%esp) is replaced with: movd %ecx, %xmm0 movd %edx, %xmm1 punpckldq %xmm1, %xmm0 movq %xmm0, 8(%esp) Differential Revision: http://reviews.llvm.org/D15946 llvm-svn: 257285	2016-01-10 09:41:22 +00:00
Michael Kuperstein	58e86bc893	[X86] Fix sitofp and uitofp instruction matching failures with long double and avx512 ... The operation action for i32 and i64 cannot be set to legal, as long double needs custom lowering.
