[Bug libc/608] New: sysdeps/mips/memset.S does not use abi independent name for temp regs

[shay_gal-on at pmc-sierra dot com]

Currently memset uses t4,t5,t6,t7, and will not compile with n32 ABI.
regdef.h defines ta0,ta1,ta2,ta3 as abi independent names which can be used for
the purpose.

Is the problematic file mips/memcpy.S, not mips/memset.S?

I discussed with Thiemo Seufer and he said n32 ABI should be compiled
with sysdeps/mips/mips64/memcpy.S, not sysdeps/mips/memcpy.S.  Do you
use the pure latest upstream cvs?  If so, is your compilation used
mips64/memcpy.S?

Subject: RE:  sysdeps/mips/memset.S does not use abi indepen
	dent name for temp regs

It is possible that my configuration is somehow screwed up, but when trying to build, I ran into this issue (mips/memcpy.S trying to compile, and complaining about the register names).
I am building for mips-linux target, with -mabi=n32 (trying to multilib n32, o32 abis).

That's the problem.  mips-linux does not support n32; you have to use a target
of mips64-linux to build n32 libraries.  The mips64 configuration should support
all three ABIs.
