Subject: [PATCH] Fix E500 with SPE errors with the _Decimal64 type
[gcc]
2014-04-21 Michael Meissner <meissner-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>
PR target/60735
* config/rs6000/rs6000.md (mov<mode>_softfloat32, FMOVE64 case):
If mode is DDmode and TARGET_E500_DOUBLE allow move.
* config/rs6000/rs6000.c (rs6000_debug_reg_global): Print some
more debug information for E500 if -mdebug=reg.
[gcc/testsuite]
2014-04-21 Michael Meissner <meissner-23VcF4HTsmIX0ybBhKVfKdBPR1lH4CV8@public.gmane.org>
PR target/60735
* gcc.target/powerpc/pr60735.c: New test. Insure _Decimal64 does
not cause errors if -mspe.
Upstream status: Accepted
This solves upstream bug 60735
(https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60735).
Patch taken from https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=209664
