re PR tree-optimization/41661 (ICE due to IPCP trying to create/fold a REAL typed comparision)
2009-10-13 Martin Jambor <mjambor@suse.cz>
PR tree-optimization/41661
* ipa-prop.c (compute_complex_pass_through): Allow only operations
that are tcc_comparisons or do not change the type in any
un-usleless way.
* ipa-cp.c (ipcp_lattice_from_jfunc): Request boolean type when
folding tcc_comparison operations.
* testsuite/gcc.c-torture/compile/pr41661.c: New test.
