John David Anglin - Sept. 14, 2013, 9:17 p.m.
The attached change fixes a bug in pa_expand_prologue.  The mode  
argument in the calls
to "gen_rtx_POST_INC" should be the same as "tmpreg" (word_mode).

Tested on hppa2.0w-hp-hpux11.11, hppa64-hp-hpux11.11 and hppa-unknown- 
linux-gnu.
Committed to trunk, 4.8 and 4.7.
