re PR target/60203 (Support long double/_Decimal128 direct move on power8)
2014-02-18 Michael Meissner <meissner@linux.vnet.ibm.com>
PR target/60203
* config/rs6000/rs6000.md (mov<mode>_64bit, TF/TDmode moves):
Split 64-bit moves into 2 patterns. Do not allow the use of
direct move for TDmode in little endian, since the decimal value
has little endian bytes within a word, but the 64-bit pieces are
ordered in a big endian fashion, and normal subreg's of TDmode are
not allowed.
(mov<mode>_64bit_dm): Likewise.
(movtd_64bit_nodm): Likewise.
From-SVN: r207868
