Unable to compile sparc32 version of openbios with gcc 4.x

[Aurelien Jarno]

Hi,

I am unable to compile openbios for sparc32 (on a sparc64 host) using
gcc 4.x (tested with 4.0, 4.2 and 4.3), it looks like it does not like
the TI mode and the __uint128_t type:

| libgcc/libgcc.h:14: error: unable to emulate ‘TI’
| libgcc/libgcc.h:18: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__udivmodti4’
| libgcc/libgcc.h:22: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__divti3’
| libgcc/libgcc.h:23: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__udivti3’
| libgcc/libgcc.h:26: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘__umodti3’

Anyone as an idea of a fix?

Thanks,
Aurelien

It looks like GCC 4 does not provide TI (128 bit) types anymore. But
the types are only needed for Sparc64, so we can disable these
prototypes for now.

Should be fixed in r254. Thanks for reporting.
