Author: rguenth Date: Tue Jul 15 15:07:46 2008 New Revision: 137843 URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=137843 Log: 2008-07-15 Richard Guenther <[EMAIL PROTECTED]> PR middle-end/36369 * c-common.c (strict_aliasing_warning): Do not warn for TYPE_REF_CAN_ALIAS_ALL pointers. (c_common_get_alias_set): may_alias types are not special. * tree.c (build_pointer_type_for_mode): Look up the may_alias attribute and set can_ref_all accordingly. (build_reference_type_for_mode): Likewise. * doc/extend.texi (may_alias): Clarify. * gcc.dg/Wstrict-aliasing-bogus-ref-all.c: New testcase. Added: trunk/gcc/testsuite/gcc.dg/Wstrict-aliasing-bogus-ref-all.c Modified: trunk/gcc/ChangeLog trunk/gcc/c-common.c trunk/gcc/doc/extend.texi trunk/gcc/testsuite/ChangeLog trunk/gcc/tree.c -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=36369
