Bugzilla Bug 180385

assembler lacks "palignr" instruction that blas-goto requires on Core2-based
systems

Reproducible: Always

Actual Results:  
zcopy_sse_core2.S: Assembler messages:
zcopy_sse_core2.S:242: Error: no such instruction: `palignr $4,%xmm0,%xmm1'
zcopy_sse_core2.S:247: Error: no such instruction: `palignr $4,%xmm9,%xmm2'
zcopy_sse_core2.S:252: Error: no such instruction: `palignr $4,%xmm10,%xmm3'
zcopy_sse_core2.S:257: Error: no such instruction: `palignr $4,%xmm11,%xmm4'


Expected Results:  
Correct compilation

sci-libs/blas-goto version and emerge --info please.

blas-goto-1.14, although the same problem occurs with 1.15 when installing it
outside of portage

Added needed info

Please correct me if I am wrong but AFAIK "palignr" is part of
SSSE3 (note the additional "S") which is not supported
by either gcc-4.1 or gcc-4.2. I believe SSSE3 support will 
be part of gcc-4.3. That said, I am not sure if this piece
of code will compile using gcc in the near future.

cheers,
Markus 

I thought about this some more and what really matters here I guess
is not gcc but rather gas. That said, I believe that the gas version that 
ships with binutils-2.17 should be able to do these ssse3 instructions. Could
you give this a try (you're currently at binutils-2.16).

Markus

Excellent, success!  binutils-2.17 does indeed work.  Thanks Markus!

Great! I guess we better put this requirement into DEPEND.

best,
Markus

I've just added this dependence on binutils-2.17 to the 
blas-goto-1.14 ebuild.


cheers,
Markus
