            Bug ID: 60876
           Summary: 2014-04-17 change to mqchmode.h breaks PowerPC
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: meissner at gcc dot gnu.org

The change on 2014-04-17 to machmode.h had a side effect of breaking the
PowerPC builds, due to the fact that the PowerPC code in rs6000.c used integers
in two places where GET_MODE_SIZE was used, and this now causes the following
error:

rs6000_setup_reg_addr_masks()’:
