-Upstream-Status: Pending
-
-Backport of bugfix in gcc-4.6.x and mainline that address bug 44618 in
-which we get wrong code generation with -Os -frename-registers.

- PR target/44618
- * config/rs6000/rs6000.md (save_gpregs_<mode>): Replaced pattern
- with a set of similar patterns, where the MATCH_OPERAND for the
- function argument is replaced with individual references to hardware
- registers.
- (save_fpregs_<mode>): Ditto
- (restore_gpregs_<mode>): Ditto
- (return_and_restore_gpregs_<mode>): Ditto
- (return_and_restore_fpregs_<mode>): Ditto
- (return_and_restore_fpregs_aix_<mode>): Ditto
-
- * gcc.target/powerpc/outofline_rnreg.c: New testcase.
