             Bug #: 50878
           Summary: ARM bootstrap failure on insn-preds.c with error:
                    dominator of 12 should be 6, not 5
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: michael.hope@linaro.org


trunk r180460 fails during stage 2 with the following error:

../../../gcc-4.7~/gcc/config/arm/predicates.md: In function 'bool
constraint_satisfied_p(rtx, constraint_num)':
../../../gcc-4.7~/gcc/config/arm/predicates.md:924:1: error: dominator of 12
should be 6, not 5
../../../gcc-4.7~/gcc/config/arm/predicates.md:924:1: internal compiler error:
in verify_dominators, at dominance.c:1041

This happens on ARM in an ARMv5 configuration and Cortex-A9 configuration.

The full build log is here:

http://builds.linaro.org/toolchain/gcc-4.7~svn180460/logs/armv7l-natty-cbuild205-tcpanda04-cortexa9r1/gcc-build.txt

The Cortex-A9 configure flags are:

--prefix=/scratch/cbuild/slave/slaves/tcpanda04/gcc-4.7~svn180460/gcc/default/install
--enable-languages=c,c++,objc,obj-c++,fortran,lto --with-mode=thumb
--with-arch=armv7-a --with-tune=cortex-a9 --with-float=softfp --with-fpu=neon

Michael, can you attach the preprocessed source of insn-preds.c?

--- Comment #10 from Joel Sherrill <joel at gcc dot gnu.org> 2011-10-30 23:52:21 UTC ---
FWIW I am using a native gcc on x86_64 to build cross *-rtems4.11 targets.  

gcc (GCC) 4.7.0 20111029 (experimental)

I think this is a native issue (x86_64-unknown-linux-gnu) that is showing up on
multiple odd situations.

I see this compiling arm-rtems4.11

And I think this is the same thing I saw with the native compiler of
yesterday's vintage compiling the head of binutils-cvs to target
sparc-rtems4.11

/users/joel/test-gcc/binutils-cvs/src/bfd/sunos.c: In function
‘sunos_check_dynamic_reloc’:
/users/joel/test-gcc/binutils-cvs/src/bfd/sunos.c:2328:1: error: dominator of
26 should be 20, not 19
/users/joel/test-gcc/binutils-cvs/src/bfd/sunos.c:2328:1: internal compiler
error: in verify_dominators, at dominance.c:1041

I can provide preprocessed source if someone needs it.

Posted fix has been approved:
http://gcc.gnu.org/ml/gcc-patches/2011-10/msg02787.html, but the patch does not
fix PR50908, which is a similar, but more complex problem.

The tentative patch for PR50908 does fix both PR50908 and this PR. I intend to
mark this PR a duplicate of PR50908 once that one's fixed.
