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.
