            Bug ID: 94825
           Summary: libphobos test case failures on powerpc64
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at linux dot vnet.ibm.com
  Target Milestone: ---

A bunch of the newly activated libphobos test cases fail on powerpc64.  I saw
this on both BE and LE.

    libphobos: Add power*-*-linux* as a supported target

    libphobos/ChangeLog:

        * configure: Regenerate.
        * configure.tgt: Add power*-*-linux* as a supported target, only
        building libdruntime.
        * m4/druntime/cpu.m4 (DRUNTIME_CPU_SOURCES): Add cases for powerpcle
        and powerpc64le target cpus.

    libphobos: Fix multilib powerpc64 builds

    Multilibs should not have been split up as two logically different CPU,
    so at configure time, powerpc64 was being detected, but none of the
    32-bit support files were being compiled in.

    libphobos/ChangeLog:

            PR d/94825
            * configure: Regenerate.
            * libdruntime/Makefile.am (DRUNTIME_SOURCES_CONFIGURED): Add both
            switchcontext.S and callwithstack.S if DRUNTIME_CPU_POWERPC.
            * libdruntime/Makefile.in: Regenerate.
            * libdruntime/config/powerpc/switchcontext.S: Add !__PPC64__
guards.
            * libdruntime/config/powerpc64/callwithstack.S: Add __PPC64__
guards.
            * m4/druntime/cpu.m4 (DRUNTIME_CPU_SOURCES): Define
DRUNTIME_CPU_POWER
            for all powerpc biarchs.  Remove DRUNTIME_CPU_POWER64 conditional.

    d: Merge upstream dmd 934df6f8c, druntime 7bdd83d7

    Corrects a previous change made to the SPARC stdc bindings, and
    backports PPC-related fixes.  The library and language testsuite now
    passes fully on powerpc64le-linux-gnu.
