tree-ssa-alias.c (new_type_alias): New procedure to create a type memory tag for a pointer with a may-alias set...
2005-05-29 Keith Besaw <kbesaw@us.ibm.com>
* tree-ssa-alias.c (new_type_alias): New procedure to
create a type memory tag for a pointer with a may-alias
set determined from a variable declaration.
* tree-flow.h: export declaration of new_type_alias
* tree-optimize.c (init_tree_optimization_passes): document
that pass_may_alias cannot be called after pass_vectorize.
* tree-vect-transform (vect_create_data_ref_ptr): Call
new_type_alias when an type memory tag isn't available
for a reference.
(vectorizable_store): Use copy_virtual_operands to update
virtual defs in place (so that loop_version can be called).
Call mark_for_renaming for the virtual defs in case peeling
is done and virtual uses outside the loop need to be updated.
