Author: spop Date: Tue Apr 6 21:03:37 2010 New Revision: 158028 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=158028 Log: Fix 473.astar miscompile. 2010-04-05 Sebastian Pop <sebastian....@amd.com> PR middle-end/43519 * graphite-clast-to-gimple.c (max_signed_precision_type): Use lang_hooks.types.type_for_size instead of build_nonstandard_integer_type. When converting an unsigned type to signed, double its precision. (gcc_type_for_interval): Use lang_hooks.types.type_for_size. (gcc_type_for_iv_of_clast_loop): Call max_signed_precision_type. (graphite_create_new_loop_guard): When ub + 1 wraps around, use lb <= ub.
