Subject: [Bug target/36992] Very stange code for _mm_move_epi64
Date: Tue, 05 Aug 2008 14:20:00 -0000	[thread overview]
Message-ID: <20080805141909.8944.qmail@sourceware.org> (raw)

------- Comment #18 from hjl dot tools at gmail dot com  2008-08-05 14:19 -------
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?
