re PR rtl-optimization/29323 (set_nothrow_function_flags does invalid analysis on weak functions)
2006-10-10 Richard Guenther <rguenther@suse.de>
PR rtl-optimization/29323
* except.c (set_nothrow_function_flags): For functions
that do not bind local bail out early.
* decl.c (finish_function): Set TREE_NOTHROW only for
functions that bind local.
