2007-09-04 Richard Guenther <rguenther@suse.de> PR tree-optimization/33291 * tree-pretty-print.c (dump_generic_node): Dump all qualifiers for pointer types, not only first. Dump qualifiers for aggregate types as well. * tree-ssa-ccp.c (maybe_fold_offset_to_array_ref): Always use the canonical type for building ARRAY_REFs. * gimplify.c (canonicalize_addr_expr): Clean up. The correct validness check is compatibility of the pointer types. Always use the canonical type for building ARRAY_REFs and ADDR_EXPRs. * tree-ssa-forwprop.c (forward_propagate_addr_expr): Revert change that disabled propagation of ADDR_EXPRs into statements with volatile ops. * gcc.dg/volatile2.c: New testcase. * gcc.dg/pr32721.c: Adjust volatile reference pattern. * gcc.dg/tree-ssa/forwprop-1.c: Remove xfail. * gcc.dg/tree-ssa/forwprop-2.c: Likewise. * gcc.dg/tree-ssa/pr17141-1.c: Likewise.
