            Bug ID: 79076
           Summary: [sparc/solaris] bootstrap comparison failure, in-tree
                    binutils + --without-gnu-as
           Product: gcc
           Version: 4.9.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: phantall at gmail dot com
  Target Milestone: ---

Details:
* solaris 10
* gcc 4.9.2 for the initial compiler
* Followed the general configure/build pattern used by OpenCSW with a few
differences in configure flags (eg, not as many languages)
* Unlike OpenCSW I did it with binutils/cloog/mpfr/mpc/isl in-tree

The only thing that seemed to resolve the problem was to force it to use the
GNU assembler.  When using /usr/ccs/bin/as it would fail on the bootstrap
comparison.

I'm more reporting this to help out anyone who may run into this in the future
than in any hopes a fix will be forthcoming.

Here's what I did to get it configured:

     export AS=/usr/ccs/bin/as
     export AR=/usr/ccs/bin/ar
     export NM=/usr/ccs/bin/nm
     export RANLIB=/usr/ccs/bin/ranlib
     export STRIP=/usr/ccs/bin/strip
     export OBJCOPY=/opt/csw/gnu/objcopy

     export OBJDUMP=/opt/csw/gnu/objdump
     export READELF=/opt/csw/gnu/readelf

     export SHELL=/opt/csw/bin/bash
     export BUILD_SHELL=${SHELL}
     export CONFIG_SHELL=${SHELL}

     export
PATH=/opt/csw/gnu:/opt/csw/bin:/bin:/usr/bin:/usr/local/bin:/usr/sbin
     export -n LD_LIBRARY_PATH=

     mkdir -p /tmp/gcc-4.9.4/{build,src}/gcc-4.9.4
     cd /tmp/gcc-4.9.4/src

     # note: opencsw doesn't do the in-tree build and there's a
