- Subject: [RFA]rs6000-tdep.c: add nofp register set
Some ppc variants (855, 823) don't have a floating point unit.
I've just added a register set to be used for such variants.

* rs6000-tdep.c (COMMON_UISA_NOFP_REGS): New macro.
(registers_powerpc_nofp): New register set for processors
without floating point unit.
