2) Don't try to insert an i64 value into the low part of a vector with movq on an x86-32 target. This allows us to compile: __m128i doload64(short x) {return _mm_set_epi16(0,0,0,0,0,0,0,1);} into: _doload64: movaps LCPI1_0, %xmm0 ret instead of: _doload64: subl $28, %esp movl $0, 4(%esp) movl $1, (%esp) movq (%esp), %xmm0 addl $28, %esp ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48057 91177308-0d34-0410-b5e6-96231b3b80d8
