Summary: ICE with -floop-flatten
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: rguenth@gcc.gnu.org
CC: spop@gcc.gnu.org
When compiling gfortran.dg/reassoc_4.f with -O2 -ffast-math -floop-flatten I
get
gcc> /abuild/rguenther/trunk-g/gcc/testsuite/gfortran/../../gfortran
-B/abuild/rguenther/trunk-g/gcc/testsuite/gfortran/../../
-B/abuild/rguenther/trunk-g/x86_64-unknown-linux-gnu/./libgfortran/
/space/rguenther/src/svn/trunk/gcc/testsuite/gfortran.dg/reassoc_4.f -O -O2
-ffast-math -S -o reassoc_4.s -floop-flatten
PPL error code -3
PPL::C_Polyhedron::maximize(e, ...):
this->space_dimension() == 11, e.space_dimension() == 12.
thus, PPL aborts on me (that's doubly bad).
No idea if this is a GCC or PPL issue. This is PPL 0.11 with cloog 0.15.10.
