rs6000.c (rs6000_stack_info): Always set vrsave_mask for TARGET_ALTIVEC_ABI.
2012-11-19 Mans Rullgard <mans@mansr.com>
* config/rs6000/rs6000.c (rs6000_stack_info): Always set vrsave_mask
for TARGET_ALTIVEC_ABI. Zero vrsave_save_offset if
!TARGET_ALTIVEC_VRSAVE.
(rs6000_emit_prologue): For SAVE_INLINE_VLRs, check vrsave_size
not vrsave_mask.
