Summary: ICE with -floop-flatten Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: tree-optimization AssignedTo: unassig...@gcc.gnu.org ReportedBy: rgue...@gcc.gnu.org CC: s...@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.
