* [Bug c/16830] New: Including <sys/immu.h> with -mabi=n32 causes an error.

When including <sys/immu.h> (which mozilla likes to do) the compilation halts
with the masseage: parse error before pte_t. <sys/immu.h> contains some very
low-level stuff which is ignored if the exact architecture is unknown (this is
what happens then using the native compiler). The problem is that gcc defines
"R4000" when using -mabi=n32 (not then using -mabi=32), which disables the
excusion of all the low-level stuff, but doesn't include all of it either.
The solution I can think of is either to NOT define "R4000" (which again is what
the native compiler does). Or to also define "IP20", "IP22", "IP28" or
"IPMHSIM", which would make <sys/immu.h> go through the compiler but I have no
idea if it's the correct thing to do.

------- Additional Comments From rsandifo at gcc dot gnu dot org 2004-10-26 18:52 -------
Confirmed. Of the two choices you mention, I think it would be
better to remove the R3000 and R4000 macros for IRIX. Another
option would be to use fixincludes, but I think removing the
macros is better. Like you say, MIPSpro doesn't define them,
even in underscore form, and they've always been a bit flawed
anyway.
[ Reasoning: the macros sound like they're indicators of the
target ISA, but they really indicators of "64-bitness".
__mips is a better choice if you want to know the specific
ISA level and __mips64 is better if you just want to know
whether the code is 64-bit or not. ]
I'll try to bootstrap the obvious patch soon, but the irix box
I use is a bit under the weather right now.
