[Bug target/25242] New: [3.4] testsuite failure in i386-sse-2.c on x86_64-unknown-linux-gnu

[ghazi at gcc dot gnu dot org]

When running the 3.4 testsuite on x86_64-unknown-linux-gnu, I'm getting the
following error:

FAIL: gcc.dg/i386-sse-2.c (test for excess errors)

as shown here:
http://gcc.gnu.org/ml/gcc-testresults/2005-12/msg00083.html

The logfile says:

In file included from gcc/include/xmmintrin.h:1216,
                 from testsuite/gcc.dg/i386-sse-2.c:12:
gcc/include/emmintrin.h: In function `_mm_sqrt_sd':
gcc/include/emmintrin.h:248: internal compiler error: in
instantiate_virtual_regs_lossage, at function.c:3765

Other than comments, the testcase merely has these lines:

#define static
#define __inline
#include <xmmintrin.h>

I configured with --enable-checking=yes,rtl however I don't think that's
necessary to trigger the error.  I see another report without checking here
that fails the test.

Here's a reduced testcase, compile it with cc1 targetted to
x86_64-unknown-linux-gnu:

cc1 -fpreprocessed i386-sse-2.i -quiet -dumpbase i386-sse-2.c -msse -mtune=k8
-auxbase-strip i386-sse-2.s -O0 -version -o i386-sse-2.s


typedef double __v2df __attribute__ ((mode (V2DF)));
 __v2df
_mm_sqrt_sd (__v2df __A, __v2df __B)
{
  __v2df __tmp = __builtin_ia32_movsd ((__v2df)__A, (__v2df)__B);
  return (__v2df)__builtin_ia32_sqrtsd ((__v2df)__tmp);
}
