            Bug ID: 65725
           Summary: Bootstrap errors on Solaris 10 x86-64, including
                    object diffs
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: skunk at iskunk dot org
              Host: x86_64-pc-solaris2.10
            Target: x86_64-pc-solaris2.10
             Build: x86_64-pc-solaris2.10

In the course of bootstrapping on Solaris 10 x86-64, I encountered one minor
error and one not-so-minor one, that could use some attention.

1. Missing libgcc-unwind.map file

libtool: link:  /tmp/gcc-4.9.2-build/./prev-gcc/xgcc
-B/tmp/gcc-4.9.2-build/./prev-gcc/ -B/opt/tg/x86_64-pc-solaris2.10/bin/
-B/opt/tg/x86_64-pc-solaris2.10/bin/ -B/opt/tg/x86_64-pc-solaris2.10/lib/
-isystem /opt/tg/x86_64-pc-solaris2.10/include -isystem
/opt/tg/x86_64-pc-solaris2.10/sys-include    -shared -Wl,-z -Wl,text -Wl,-h
-Wl,liblto_plugin.so.0 -o .libs/liblto_plugin.so.0.0.0  .libs/lto-plugin.o   
-static-libgcc ../libiberty/pic/libiberty.a  
ld: fatal: file libgcc-unwind.map: stat failed: No such file or directory
collect2: error: ld returned 1 exit status
gmake[4]: *** [liblto_plugin.la] Error 1
gmake[4]: Leaving directory `/tmp/gcc-4.9.2-build/lto-plugin'
gmake[3]: *** [all] Error 2
gmake[3]: Leaving directory `/tmp/gcc-4.9.2-build/lto-plugin'
gmake[2]: *** [all-stage2-lto-plugin] Error 2

gmake[1]: *** [stage2-bubble] Error 2
gmake[1]: Leaving directory `/tmp/gcc-4.9.2-build'
gmake: *** [bootstrap-lean] Error 2

This can be worked around with

    $ touch /tmp/gcc-4.9.2-build/lto-plugin/libgcc-unwind.map

This error comes up twice during the bootstrap, and the workaround is the same
both times.


2. stage2 vs. stage3 diffs

I keep getting these no matter what I try. Using the system's original GCC
(3.4.3), using a non-bootstrapped 4.9.2, specifying /usr/ccs/bin/as explicitly,
nada. I also tried building with the Solaris vendor compilers, but got an
obstack-related error that looks messy (I can file that separately if this is
of interest).

At configure time, the build process determines

    checking how to compare bootstrapped objects... cmp $$f1 $$f2 16 16

and if I run that same comparison (plus -l) on the objects reported to differ,
I get relatively small diffs. Could it be that these diffs are spurious?

$ cat objects.txt | while read x; do echo stage2-$x vs. stage3-$x; cmp -l
stage2-$x stage3-$x 16 16; done
