             Bug #: 54373
           Summary: [4.7/4.8 Regression]: build fails for
                    mmix-knuth-mmixware libobjc GCC_NO_EXECUTABLES
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: build, ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: target
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hp@gcc.gnu.org
              Host: x86_64-unknown-linux-gnu
            Target: mmix-knuth-mmixware


Some time after the 4.6 branch building binutils separately (not in a combined
tree) broke.  A build of binutils, installing that, then building gcc with PATH
including the binutils installation now results in:

Similarly for trunk, for example revision 190649.

For failing versions, I see in gccobj/mmix/libobjc/config.log traces of basic
compilation problems:

thus I label this a target problem (maybe even a binutils and not gcc problem),
though the libobjc failure is far from gracious.

To wit, a build with in-tree binutils works.  But, it works for the wrong
reason: there's a bug in the extraction of gas and ld version, which has the
effect of turning off every optional (and version-tested) gas and ld feature. 
Thus, for in-tree binutils, support for .hidden is turned off (*) and
corresponding #ifs in crtstuff.c cause the code to be different.  It works but
for the wrong reason.

The linker error messages indicates a linker bug, because the offending insn:

        LDA $252,__TMC_END__+7

or actually, the "__TMC_END__+7" operand, is valid; there are no restrictions
for base-plus-offset symbol expressions (like, not having an offset or offsets
being a multiple of 8).

I'm keeping this PR open and assigned instead of closing as invalid until I
know this is the only build-breaking bug (or libobjc-build-breaking bug).

It's yet another configure bug that .hidden is turned on for the linker: it's
turned on for *all* GNU linkers after a certain date, which doesn't really
matter unless it's turned for the assembler as well.  But turning .hidden on
for the MMIX binutils assembler is kind-of correct, because with non-default
linker options, ELF is produced and thus .hidden is "supported" (which still
doesn't really matter for this static-only linker).
