             Bug #: 52172
           Summary: [4.7 FreeBSD ia64 regression] stage 3 Bootstrap
                    comparison failure
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal

Trying to update from gcc-4.7.0.20120107 to 4.7.0.20120128

How did you configure?  A bootstrap on ia64-linux worked fine for me today.

Just "make configure" using FreeBSD ports infrastructure, same as always.

Or do you want to see config.log?
If yes, please let me know which one, and I'll post it.

@OP: If you get bootstrap working again, could you please also run a "make
check" and post the results to the gcc-testresults mailing list using the
contrib/test_summary script?

Same for gcc-4.7-20120204.
Is this snapshot after r183751?

According to http://gcc.gnu.org/ml/gcc/2012-02/msg00111.html it is revision
183896, so yes it is after r183751 (4.7.0.20120107 was r182982 and
4.7.0.20120128 r183669).

--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-02-10 15:10:54 UTC ---
So, can you from your build log paste the command to compile var-tracking.c
with the stage2 gcc and rerun it in the gcc subdir with additional
-fcompare-debug option?  It might be a -fcompare-debug issue (in that case
rerun with -save-temps option and attach var-tracking.i together with the exact
command line option used to compile it, or stage1 or stage2 cc1/cc1plus might
be miscompiled.

--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> 2012-02-13 20:26:58 UTC ---
Created attachment 26654
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26654
vartrack.ii

Slightly reduced testcase.
Reproduceable with
./g++ -B ./ -S -fcompare-debug -g -O2 -fno-exceptions -fno-rtti -pedantic
-fno-common vartrack.ii  --param min-nondebug-insn-uid=10000
(the param in order to make the debugging at least bearable by making the uids
match for non-debug insns).

The problem seems to be in remove_useless_values happening at different times
during sched2 (part of ia64 mach pass).  There we for a DEBUG_INSN insn do
first cselib_lookup_from_insn (... , insn), then call cselib_subst_to_values.
Unfortunately the latter means cselib_current_insn is NULL and
promote_debug_loc decides to promote it (and clear setting_insn) even for a
debug stmt value that -g0 compilation doesn't touch in any way.
