            Bug ID: 236839
           Summary: gcc8 failed to compile on sparc64 platform (FreeBSD
                    12.0 STABLE)
           Product: Ports & Packages
           Version: Latest
          Hardware: sparc64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: Individual Port(s)
          Assignee: [hidden email]
          Reporter: [hidden email]
                CC: [hidden email]
             Flags: maintainer-feedback?([hidden email])
                CC: [hidden email]
          Assignee: [hidden email]

GCC8 fails to compile on SPARC64.  The port fails with the compile error
messages (truncated for brevity) included below.  

Errors from the build (i.e. cd /usr/ports/lang/gcc8 && make)

---> CUT HERE <---
Comparing stages 2 and 3

===> Compilation failed unexpectedly.
---> END CUT <---

Summary:

It would *appear* as though that GCC is comparing the output from the stage2
and stage3 compiles, but stage 3 is being built with debug info being attached.

This conclusion is based on examination of some of the files in question from
the error above.

--- Comment #1 from Gerald Pfeifer <[hidden email]> ---
I have to admit that the most sensible option at this point may be
removing sparc64 from the list of platforms supported by lang/gcc8
(and newer). And making sparc64 tier 3 given that the platform is,
essentially, dead and doesn't really have production usage on FreeBSD.

toolchain@ and Andreas, what's your take?  Any idea on how to fix this?

URL: https://svnweb.freebsd.org/changeset/base/354468

Log:
  arch.7: claim 12.x as the last architecture with sparc64 support

  GCC 4.2.1 is being removed before FreeBSD 13, as are some other
  components required by FreeBSD/sparc64.  Contemporary GCC does not build
  and there is currently no indication that anyone is going to address
  these issues.

As the original creator of the PR.  I've since been able to butcher the GCC
build to get GCC 8.3.0 to build and so far seems to work without any issue.  I
do however need to clean up the patches required in order to make this
acceptable as right now ... these are not acceptable in any way, shape or form
for general distribution.  If someone specifically *needs* the package it is
available as a precompiled txz ... all you need to do is *ask*.

For lack of a better option I am closing this as Overcome by Events.

If you have any general patches for GCC on FreeBSD on sparc64, andreast
or me may be able to help get those upstream, and if it's a config change
in the port let's focus on gcc10-devel which will soon lead to lang/gcc10
when GCC 10.1 releases upstream.
