PR tree-optimization/16688 PR tree-optimization/16689 * tree-ssa-alias.c (setup_pointers_and_addressables): Remove unnecessary initialization of 'tag'. (get_tmt_for): Check that the new type tag has the same alias set as the pointed-to type. (group_aliases): Only regular variables need to be removed from the alias set of a name tag. * tree-ssa-copy.c (may_propagate_copy): Do not allow copy propagation if the two types are not compatible. (merge_alias_info): Rename from replace_ssa_names_ann. Add more checking. (replace_exp_1): If both arguments are SSA_NAMEs, check that the propagation can be done. Only call merge_alias_info on pointers. (propagate_value): Likewise. * tree-ssa-copyrename.c: Include langhooks.h. (copy_rename_partition_coalesce): Call replace_ssa_name_symbol to do the merging. Do not coalesce variables with incompatible types. (rename_ssa_copies): Call replace_ssa_name_symbol. * tree-ssa.c (verify_ssa_name): Verify that the SSA_NAME has the same type as the underlying _DECL. * tree-ssanames.c (replace_ssa_name_symbol): New function. * tree.h (replace_ssa_name_symbol): Declare.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
