             Bug #: 50650
           Summary: [4.7 Regression] ICE in vect_is_simple_use_1, at
                    tree-vect-stmts.c:5689
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: markus@trippelsdorf.de


The following ICE happens when building the latest Mozilla JavaScript Engine:

c++ -o /dev/null -S -w -Wfatal-errors -fpermissive -fpreprocessed -O3
LoopState.ii
/var/tmp/mozilla-central/js/src/methodjit/LoopState.cpp: In member function
‘bool js::mjit::LoopState::init(jsbytecode*,
js::mjit::MacroAssemblerTypedefs::Jump, jsbytecode*)’:
/var/tmp/mozilla-central/js/src/methodjit/LoopState.cpp:106:1: internal
compiler error: in vect_is_simple_use_1, at tree-vect-stmts.c:5689

A reduced testcase is attached.

 % c++ -w -O3 moz_testcas.ii
moz_testcas.ii: In member function ‘bool js::mjit::LoopState::init(jsbytecode*,
js::mjit::MacroAssemblerTypedefs::Jump, jsbytecode*)’:
moz_testcas.ii:145:6: internal compiler error: in vect_is_simple_use_1, at
tree-vect-stmts.c:5689

This only happens with -O3.

New Revision: 179653

URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=179653
Log:
    PR tree-optimization/50650
    * tree-vect-patterns.c (vect_recog_mixed_size_cond_pattern): Don't
    call vect_is_simple_cond here, instead fail if cond_expr isn't
    COMPARISON_CLASS_P or if get_vectype_for_scalar_type returns NULL
    for cond_expr's first operand.
    * tree-vect-stmts.c (vect_is_simple_cond): Static again.
    * tree-vectorizer.h (vect_is_simple_cond): Remove prototype.

    * gcc.c-torture/compile/pr50650.c: New test.
