tree-flow.h (struct ptr_info_def): Add align and misalign fields.
2010-08-12 Richard Guenther <rguenther@suse.de>
* tree-flow.h (struct ptr_info_def): Add align and misalign fields.
* tree-ssa-alias.c (get_ptr_info): Move ...
* tree-ssanames.c (get_ptr_info): ... here. Initialize
align and misalign fields conservatively.
* tree-ssa-ccp.c (ccp_finalize): From partially constant pointers
derive alignment information.
(evaluate_stmt): Derive alignment information from memory
allocation functions.
* tree.h (get_pointer_alignment): Make unsigned.
* builtins.c (get_object_alignment): Use alignment information we
have computed for pointers.
(get_pointer_alignment): Likewise. Make conservative, return
and unsigned value.
(expand_builtin_strlen): Adjust.
(expand_builtin_memcmp): Likewise.
(expand_builtin_strcmp): Likewise.
(expand_builtin_strncmp): Likewise.
(get_builtin_sync_mem): Use at least mode alignment.
(fold_builtin_memset): Adjust.
(fold_builtin_memory_op): Likewise.
* gimple-pretty-print.c (dump_gimple_phi): Alongside alias
information also dump pointer alignment knowledge.
(dump_gimple_stmt): Likewise.
