We are trying to build a library on Solaris 11.3. We installed GCC 5.4
so we have an update compiler available. The library uses SHA
intrinsics. The build process is driven through the compiler driver.
The build is failing with:
g++ -g2 -O3 -fPIC -m64 -Wa,--divide -msse4.2 -msha -c sha-simd.cpp
{standard input}: Assembler messages:
{standard input}:166: Error: no such instruction: `sha1rnds4 $0,%xmm0,%xmm7'
{standard input}:199: Error: no such instruction: `sha1nexte %xmm0,%xmm2'
{standard input}:206: Error: no such instruction: `sha1msg1 %xmm0,%xmm10'
{standard input}:212: Error: no such instruction: `sha1rnds4 $0,%xmm2,%xmm9'
{standard input}:239: Error: no such instruction: `sha1nexte %xmm2,%xmm7'
...
It seems the Solaris assembler cannot handle SHA extensions at this time:
/usr/bin/as -V </dev/null
as: Studio 12.5 Compiler Common 12.5 SunOS_i386 s11_3sru9_2 05/16/2016
We would like to ask GCC to use NASM instead of 'as'. On Mac's we do
similar with `-Wa,-q`. The option uses Clang's integrated assembler
instead of `as`.
Is there a way to tell GCC to use a different assembler? Or is there a
way to tell GCC to use NASM for a particular source file?
