Re: patch: altivec vrsave

Thank you for the patch; it appears that xgcc needs to pass another
option to the assembler on MacOS X.  Or maybe I need to specify the
correct powerpc architectures somehow in configure.

Here is the error messages:

and here is the part of 'man as':

      -force_cpusubtype_ALL
              By default, the assembler will produce the CPU sub-
              type ALL for the object file it is assembling if it
              finds   no   implementation-specific  instructions.
              Also by default, the assembler will allow implemen-
              tation-specific  instructions  and will combine the
              CPU subtype  for  those  specific  implementations.
              The combining of specific implementations is archi-
              tecture-dependent; if some combination of architec-
              tures  is not allowed, an error is generated.  With
              the  optional   -force_cpusubtype_ALL   flag,   all

              instructions  are allowed and the object file's CPU
              subtype will be ALL.  If  the  target  architecture
              specified   is  a  machine-specific  implementation
              (e.g., -arch ppc603,  -arch  i486),  the  assembler
              will  flag as errors instructions that are not sup-
              ported on that architecture, and it will produce an
              object  file with the CPU subtype for that specific
              implementation (even if no  implementation-specific
              instructions are used).
