sorry about that. It looks like config/mips/linux.h
(TARGET_OS_CPP_BUILTINS) is broken for the O32 ABI: it contains (copied
from iris6.h)
builtin_define ("_MIPS_SIM=_MIPS_SIM_ABI32"); \
instead of this
builtin_define ("_ABIO32=1"); \
builtin_define ("_MIPS_SIM=_ABIO32"); \
in my current config/mips/iris6.h (not yet reviewed/installed).
_MIPS_SIM_ABI32 is only defined (on IRIX 6.5) in <sgidefs.h>. The change
above matches what SGI's MIPSpro C compiler does and is obviously correct.
There is another place in mips.h where _MIPS_SIM_ABI32 is used. It should
be corrected to use _ABIO32 like all the other _MIPS_SIM tests.
I'll prepare a patch.
