* config/rs6000/constraints.md: constraint "e": New, CR1_REGS if
XILINX_FPU_CR1_FIX set, else CR_REGS.
* config/rs6000/rs6000.h: XILINX_FPU_CR1_FIX, CR1_REGS: New,
enum reg_class: add mask for CR1_REGS
* config/rs6000/rs6000.md: *cmpsf_internal1, *cmpdf_internal1,
*cmptf_internal1, *cmptf_internal2: convert "y" constraint (CR_REGS)
to "e" contstraint.
* config/rs6000/xilinx.h: XILINX_FPU_CR1_FIX: New, set if PPC405 and
rs6000_xilinx_fpu
Sorry, no. If Xilinx needs this, it should be in a private patch.
