Summary: Missing IEEE_ONE on MIPS

Initial Comment:
On my MIPS machine, IEEE_ONE definition was missing and
make linux-solo failed early.  I believe MIPS also uses
IEEE floating point format.

OK, it looks like __mips is defined when using the IRIX C
compiler and _MIPS_ARCH is defined when using gcc.  I've
added checks for those two symbols in imports.h
I'll close this bug someday if there are no further additions.

you wouldn't; but you might try to compile them on a PCI
MIPS system running Linux.

Why would you try to compile the DRI drivers on an IRIX system?

I've updated imports.h to check for __hppa__ and hpux.

likewise for hppa machines:

.. || defined(__hppa__) || defined(hpux)

Sorry for not reporting the details.  It first failed in
src/mesa/drivers/dri/r200/r200_state_init.c.  (I omitted
Intel chips from the build as they're not useful for MIPS.)
 The Mesa core seems OK.

Where exactly does the compilation fail?

This may need to be adjusted for your MIPS machine. 

IEEE_ONE is defined in src/mesa/main/imports/h

/***
 *** USE_IEEE: Determine if we're using IEEE floating point
 ***/
#if defined(__i386__) || defined(__386__) ||
defined(__sparc__) ||     defined(__s390x__) || defined(__powerpc__) ||     defined(__AMD64__) ||     defined(ia64) || defined(__ia64__) ||     (defined(__alpha__) && (defined(__IEEE_FLOAT) ||
!defined(VMS)))
#define USE_IEEE
#define IEEE_ONE 0x3f800000
#endif
