re PR middle-end/34163 (10% performance regression since Nov 1 on Polyhedron's "NF" on AMD64)
2009-07-03 Richard Guenther <rguenther@suse.de>
PR middle-end/34163
* tree-chrec.c (chrec_convert_1): Fold (T2)(t +- x) to
(T2)t +- (T2)x if t +- x is known to not overflow and
the conversion widens the operation.
* Makefile.in (tree-chrec.o): Add $(FLAGS_H) dependency.
* gfortran.dg/pr34163.f90: New testcase.
