With -msse4, we got
bash-3.2$ ./xgcc -B./ -msse4 -S
/export/gnu/src/gcc-work/gcc/gcc/testsuite/gcc.target/i386/pr36992-1.c
bash-3.2$ ./xgcc -B./ -msse4 -S
/export/gnu/src/gcc-work/gcc/gcc/testsuite/gcc.target/i386/pr36992-1.c -O2
bash-3.2$ cat pr36992-1.s
.file "pr36992-1.c"
.text
.p2align 4,,15
.globl test
.type test, @function
test:
.LFB516:
pextrq $0, %xmm0, %rax
pxor %xmm0, %xmm0
pinsrq $0, %rax, %xmm0
ret
Why can't we just emit movq pattern for _mm_move_epi64?
