2008-07-04 Richard Guenther <rguenther@suse.de>
* tree-ssa-structalias.c (lookup_vi_for_tree): Declare.
(do_sd_constraint): Handle a dereference of ESCAPED and CALLUSED
properly to compute the reachability set if we do field-sensitive PTA.
* invoke.texi (max-fields-for-field-sensitive): Document default.
* opts.c (decode_options): Set max-fields-for-field-sensitive to
100 for optimize >= 2.
* gcc.dg/tree-ssa/pta-callused.c: New testcase.
