When I feed the following program "ice.c" typedef double v2df __attribute__ ((mode(V2DF))); int main() { volatile v2df xd; v2df yd = { 1.0, 4.0 }; xd = __builtin_ia32_cvtps2pd(__builtin_ia32_rsqrtps(__builtin_ia32_cvtpd2ps(yd))); return 0; }
to GCC 3.4.3 with gcc -march=pentium4 -mcpu=pentium4 -msse2 -funroll-loops ice.c -o ice I get the following: ice.c: In function `main': ice.c:11: internal compiler error: in simplify_binary_operation, at simplify-rtx.c:1202 If I omit "-funroll-loops", everything seems to work.
