re PR target/59054 (Powerpc -O0 -mcpu=power7 generates sub-optimal code to load 0)
2013-11-12 Michael Meissner <meissner@linux.vnet.ibm.com>
PR target/59054
* config/rs6000/rs6000.md (movdi_internal32): Eliminate
constraints that would allow DImode into the traditional Altivec
registers, but cause undesirable code generation when loading 0 as
a constant.
(movdi_internal64): Likewise.
(cmp<mode>_fpr): Do not use %x for CR register output.
(extendsfdf2_fpr): Fix constraints when -mallow-upper-df and
-mallow-upper-sf debug switches are used.
[gcc/testsuite]
