SunOS 5.8 Generic_108528-04 sun4u sparc SUNW,Ultra-80
>Description:
The specs file handles -mcpu=ultrasparc and -mcpu=v9
differently in the %asm_cpu target (or rather -mcpu=v9
is not handled at all in that target). This has the
effect that as will reject v8 assembler.
>How-To-Repeat:
Compile something like

#if defined(__sparc_v9__) && defined(__GNUC__)

void membar(void)
{
  __asm__ __volatile__ ("membar #LoadStore");
}

#endif

with eg

gcc -mcpu=v9 -c foo.c

and as will complain about using v8plus opcodes.

gcc -mcpu=ultrasparc -c foo.c

and it won't complain.
>Fix:
Fix the specs file so that it handles -mcpu=ultrasparc and -mcpu=v9 equally.
