           Summary: [10 Regression] AIX bootstrap failure with
                    builtin-types.def change
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: bootstrap

  Target Milestone: ---
            Target: powerpc-ibm-aix*

<built-in>: fatal error: internal error: builtin function '__builtin_ddedpd'
had an unexpected return type 'DD'

AIX does not enable OPTION_MASK_DFP in the CPU masks.

Either rs6000-builtin.def should not define the builtin or rs6000-call.c
rs6000_common_init_builtins should not define the builtin.
