Rafael Espindola	5cab029e4b	Don't get confused if a extern "C" builtin function is redeclared without ... the extern "C". llvm-svn: 171260	2012-12-30 17:23:09 +00:00
Matt Beaumont-Gay	335e653fe6	Improve the correctness and accuracy of the message for -Wdynamic-class-memaccess ... llvm-svn: 138074	2011-08-19 20:40:18 +00:00
Douglas Gregor	18739c343c	Teach the warning about non-POD memset/memcpy/memmove to deal with the ... __builtin_ versions of these functions as well as the normal function versions, so that it works on platforms where memset/memcpy/memmove are macros that map down to the builtins (e.g., Darwin). Fixes <rdar://problem/9372688>. llvm-svn: 133173	2011-06-16 17:56:04 +00:00
Chandler Carruth	ac6872655b	Clean up the "non-POD memaccess" stuff some. This adds a properly named ... diagnostic group to cover the cases where we have definitively bad behavior: dynamic classes. It also rips out the existing support for POD-based checking. This didn't work well, and triggered too many false positives. I'm looking into a possibly more principled way to warn on the fundamental buggy construct here. POD-ness isn't the critical aspect anyways, so a clean slate is better. This also removes some silliness from the code until the new checks arrive. llvm-svn: 132534	2011-06-03 06:23:57 +00:00
