dct64_sse.c摘录如下：
33 void dct64_sse(real *a,real *b,real *c)
34 {
35 static real __attribute__ ((aligned(16))) b1[0x20];
36 static real __attribute__ ((aligned(16))) b2[0x20];
37 static real const one = 1.f;
38
39 short *out0 = (short*)a;
40 short *out1 = (short*)b;
41
42 {
43 real *costab = costab_mmx;
44 int i;
45
46 for (i = 0; i < 0x20 / 2; i += 4)
47 {
48 asm(
49 "movaps %2, %%xmm3\n\t"
50 "shufps $27, %%xmm3, %%xmm3\n\t"
51 "movups %3, %%xmm1\n\t"

我查了网上有如下说的：
export CFLAGS=-fomit-frame-pointer
但依然没有解决，Google也不好搜，这个问题难道过于容易了？请大侠指点一下，搞了好久了，无从下手啊。
多谢。
