When compiling the following program with
gcc -g -O2 -I. -Wall -march=i686 -msse2 -c -o viterbi615_sse2.o viterbi615_sse2.c
I get:
viterbi615_sse2.c: In function `update_viterbi615_blk_sse2':
viterbi615_sse2.c:205: internal compiler error: in push_reload, at reload.c:1315
Please submit a full bug report,
with preprocessed source if appropriate.

The problem is apparently triggered by using __builtin_ia32_psrawi128(). This is
called by the SSE2 SIMD intrinsic _mm_srai_epi16(). If I rewrite my program to
call __builtin_ia32_psrawi128() directly, I get this different error message:
gcc -g -O2 -I. -Wall -march=i686 -msse2 -c -o viterbi615_sse2.o viterbi615_sse2.c
viterbi615_sse2.c: In function `update_viterbi615_blk_sse2':
viterbi615_sse2.c:184: internal compiler error: in ix86_expand_binop_builtin, at
config/i386/i386.c:13140

Confirmed. Here's a test case, can probably be further reduced:
typedef int __v2di __attribute__ ((mode (V2DI)));
typedef int __v8hi __attribute__ ((mode (V8HI)));
static __inline __v2di
_mm_sub_epi16 (__v2di __A, __v2di __B)
{
return (__v2di) __builtin_ia32_psubw128 ((__v8hi) __A, (__v8hi) __B);
}
static __inline __v2di
_mm_srai_epi16 (__v2di __A, int __B)
{
return (__v2di) __builtin_ia32_psrawi128 ((__v8hi) __A, __B);
}
void f(__v2di);
void update_viterbi615_blk_sse2 (__v2di *v)
{
int i;
for (i = 0; i < 1024; i += 2)
{
__v2di decision0, m0, m1;
m0 = v[i];
m1 = v[0];
decision0 = _mm_srai_epi16 (_mm_sub_epi16(m1, m0), 7);
f(decision0);
}
}
