constraints.md ("z" constraint): Change to CA_REGS.
2010-05-28 Segher Boessenkool <segher@kernel.crashing.org>
* config/rs6000/constraints.md ("z" constraint): Change to CA_REGS.
* config/rs6000/predicates.md: Change XER_REGNO_P to CA_REGNO_P
throughout.
* config/rs6000/rs6000.c (rs6000_reg_names, alt_reg_names): Change
"xer" to "ca".
Change XER_REGNO_P to CA_REGNO_P, XER_REGNO to CA_REGNO, and
XER_REGS to CA_REGS throughout.
* config/rs6000/rs6000.h: Same.
(ADDITIONAL_REGISTER_NAMES): Add "xer".
* config/rs6000/rs6000.md: Change XER_REGNO to CA_REGNO. Document
that mode_iterator "P" is the size for arithmetic carries as well.
* doc/md.texi (rs6000 section, "z" constraint): Fix documentation.
