Hello,
Here is a change to <sys/fpregdef.h> to provide correct cooked FP
register names for the MIPS n64 and n32 ABIs according to "MIPSpro
Assembly Language Programmer's Guide" (Silicon Graphic's document number
007-2418-004).
2009-03-01 Maciej W. Rozycki <macro@xxxxxxxxxxxxxxxx>
* sysdeps/mips/sys/fpregdef.h: Update for new ABIs.
Please apply.
Maciej
