Description of problem:
The simplified code below and any other code containing built-in SSE shift instructions can not be compiled because of an internal compiler error. 

#include <xmmintrin.h>

main() {
  __v8hi x;
  __v8hi y = __builtin_ia32_psllw128(x, (__v2di){0LL, 1LL});
}

I get the following error message:

zain.C: In function ‘int main()’:
zain.C:5: internal compiler error: in ix86_expand_builtin, at config/i386/i386.c:16322

The problem seems to be specific to the SSE2 shift instructions. Other shifts such as logical/arithmetric shift right  are causing the same error.

The log file mentioned in the error message is in the attachment.



Version-Release number of selected component (if applicable):
gcc-4.1.1-51.fc6

How reproducible:
Always


Steps to Reproduce:
Just compile any code containing built-in SSE2 shift instructions.
For example:
#include <xmmintrin.h>

main() {
  __v8hi x;
  __v8hi y = __builtin_ia32_psllw128(x, (__v2di){0LL, 1LL});
}


Actual Results:
zain.C: In function ‘int main()’:
zain.C:5: internal compiler error: in ix86_expand_builtin, at config/i386/i386.c:16322
