System: Linux vce 2.4.18-3smp #1 SMP Thu Apr 18 07:27:31 EDT 2002 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
configured with: ../configure --prefix=/tmp/local
>Description:
Program g.c, included below, causes ICE:
bash-2.05a$ /tmp/local/bin/gcc -O -msse2 /tmp/g.c
/tmp/g.c: In function `foo':
/tmp/g.c:7: internal compiler error: in simplify_unary_operation, at simplify-rtx.c:387
Please submit a full bug report,
with preprocessed source if appropriate.
>How-To-Repeat:
Compile this program with gcc -O -msse2 :
/* BEGIN PROGRAM */
typedef int V __attribute__ ((mode (V2DF)));
V foo(double x)
{
V t = __builtin_ia32_loadsd (&x);
return (V) __builtin_ia32_shufpd (t, t, 0);
}
/* END PROGRAM */
(This program is a simplification of _mm_set1_pd in xmmintrin.h)
