[PATCH] GCC 4.9 powerpc, merge DF/DD moves

2013-01-30 Thread Michael Meissner
This patch builds upon the patch in: http://gcc.gnu.org/ml/gcc-patches/2013-01/msg01457.html It merges the DFmode and DDmode moves into one pattern. In addition, it merges the -mmfpgpr code with the normal floating point moves, using a new conditional constraint (wg) that only returns FLOAT_REGS
