             Bug #: 54088
           Summary: ICE at dwarf2out.c:20632 with -O1 and sparc
    Classification: Unclassified
           Product: gcc
           Version: 4.7.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jengelh@medozas.de
              Host: sparc64-suse-linux/sparcv9-suse-linux


I have narrowed down a case whereby gcc-4.7.1-20120723 fails to compile itself
on sparcv9 and sparc64.

Host compiler:
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/sparc64-suse-linux/4.7/lto-wrapper

The new compiler is configured a bit simplified:

Please submit a full bug report,
with preprocessed source if appropriate.


This can happen in a bunch of different places; I have seen it occur with the
gcc/graphite-poly.c source file also; in both cases, it triggered this assert
in line 20332-20336:

gcc_assert (prev   
   && (CALL_P (prev)
       || (NONJUMP_INSN_P (prev)
           && GET_CODE (PATTERN (prev)) == SEQUENCE  
           && CALL_P (XVECEXP (PATTERN (prev), 0, 0)))));

A user account can be provided, if desired.

Created attachment 27883
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=27883
Full preprocessed output

Thanks for reminding me about the standard procedure :)

The minimal command is

gcc -c -O1 -g -Wno-narrowing -pedantic -Wno-long-long -Wno-variadic-macros
-Wno-overlength-strings -fno-common c-parser.i -o c-parser.o

Both -O1 and -g are required; changing the g or O level will not trigger the
issue.

I can reproduce the ICE with gcc 4.8-20120722 and 4.7-20120721, but not with
4.6-20120720, on sparc64-linux.

somewhat reduced testcase

it's not a minimal one, but still lost a good deal of lines.

Report this bug to opensuse.

This should have been fixed already by revision 187605 on the 4.7.1 branch.

Well it seems rev 187605 just did not fix it; it certainly is in the tarball.

(Richard, you prepare the tarballs that go into the openSUSE Build Service..)

The ICE continues to occur even if I leave out the handful of openSUSE patches.
