re PR target/81550 (gcc.target/powerpc/loop_align.c fails starting with r250482)
2018-01-29 Michael Meissner <meissner@linux.vnet.ibm.com>
PR target/81550
* config/rs6000/rs6000.c (rs6000_setup_reg_addr_masks): If DFmode
and SFmode can go in Altivec registers (-mcpu=power7 for DFmode,
-mcpu=power8 for SFmode) don't set the PRE_INCDEC or PRE_MODIFY
flags. This restores the settings used before the 2017-07-24.
Turning off pre increment/decrement/modify allows IVOPTS to
optimize DF/SF loops where the index is an int.
From-SVN: r257166
