--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Hmm, does the pragma happen before or after the attribute?
Because I don't get an ICE on any recent GCC but the code is all rejected.

Looks fully fixed on the trunk, in that we no longer get a warning about the
return type of _mm256_andnot_pd while compiling avx_routine . and _mm_andnot_pd
is rejected from being inlined from sse3_routine.

Created an attachment (id=18458)

another testcase
Here's another testcase that I just simplified from my attempts to use, in
Mozilla, some SSE2 code with runtime detection using CPUID. (See
https://bugzilla.mozilla.org/show_bug.cgi?id=506430 and
https://bugzilla.mozilla.org/show_bug.cgi?id=513422 .)
I'd simplified this testcase before discovering the existing bug report.
When I compile this testcase with:
/usr/local/gcc-4.4.1/bin/gcc -mno-sse2 ice.c
I get:
ice.c: In function ‘Convert_ascii_run’:
ice.c:11: internal compiler error: in emit_move_insn, at expr.c:3405

------- Comment #2 from pinskia at gcc dot gnu dot org 2009-04-21 17:42 -------
Here is one reduced testcase (an seg fault);
typedef double __m256d __attribute__ ((__vector_size__ (32) ));
static inline __m256d __attribute__((__always_inline__)) c(){}
#pragma GCC target ("no-avx")
__m256d a, b;
void avx_routine (void) { a = c();}

It also ICEs at -O0 on the trunk:
Either:
t.c: In function ‘avx_routine’:
t.c:11: internal compiler error: in emit_move_insn, at expr.c:3386
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
OR:
t.c: In function ‘avx_routine’:
t.c:11: internal compiler error: Segmentation fault
