* Comment parsing: remove HTML attribute validationDmitri Gribenko2014-04-308-120/+33
| | | | | | | | | | | | Since the community says that a blacklist is not good enough, and I don't have enough time now to implement a proper whitelist, let's just remove the attribute validation. But, nevertheless, we can still communicate in the generated XML if our parser found an issue with the HTML. But this bit is best-effort and is specifically called out in the schema as such. llvm-svn: 207712
* PR19601: std::remove_if does not really remove the elements.Arnaud A. de Grandmaison2014-04-301-2/+3
| | | | | | | | It moves them at the end of the range instead, so an extra erase is needed. It is strange that this code works without the erase. On the other hand, removing the remove_if will make fail some tests. llvm-svn: 207696

* Let stddef.h respect __need_{wchar_t, size_t, NULL, ptrdiff_t, wint_t}.Nico Weber2014-04-303-5/+105
| | | | | | | | | | | | | | | | glibc expects that stddef.h only defines a single thing if either of these defines is set. For example, before this change, a C file containing #include <stdlib.h> int ptrdiff_t = 0; would compile with gcc but not with clang. Now it compiles with clang too. This also fixes PR12997, where older versions of the Linux headers would define NULL incorrectly, and glibc would define __need_NULL and expect stddef.h to redefine NULL with the correct definition. llvm-svn: 207606
* Defer loading any pending update records until we've finished deserializing.Richard Smith2014-04-305-19/+20
| | | | | | | This fixes a bug where an update record causes us to load an entity that refers to an entity we've not finished loading yet, resulting in badness. llvm-svn: 207603
* Drop non-cfi assembly support from clang.Rafael Espindola2014-04-307-66/+2
| | | | | | | | | | | | | | After this patch clang will ignore -fdwarf2-cfi-asm and -ffno-dwarf2-cfi-asm and always print assembly that uses cfi directives. In llvm, MC itself supports cfi since the end of 2010 (support started in r119972, is reported in the 2.9 release notes). In binutils the support has been around for much longer. It looks like support started to be added in May 2003. It is available in 2.15 (31-Aug-2011, 2.14 is from 12-Jun-2003). llvm-svn: 207602

* [analyzer] Improve test from r207486.Jordan Rose2014-04-291-5/+8
| | | | | | | | | | | | The constructor that comes right before a variable declaration in the CFG might not be the initialization of that variable. Previously, we just checked that the variable's initializer expression was different from the construction expression, but forgot to see whether the variable had an initializer expression at all. Thanks for the prompting, David. llvm-svn: 207562
* [analyzer] Don't assert when combining using .* on a temporary.Jordan Rose2014-04-292-1/+25
| | | | | | | | | | | | | While we don't model pointer-to-member operators yet (neither .* nor ->*), CallAndMessageChecker still checks to make sure the 'this' object is not null or undefined first. However, it also expects that the object should always have a valid MemRegion, something that's generally important elsewhere in the analyzer as well. Ensure this is true ahead of time, just like we do for member access. PR19531 llvm-svn: 207561

* AST: Fix visibility calculation for VarTemplateSpecializationDeclDavid Majnemer2014-04-292-0/+12
| | | | | | | | | | | | It is possible that a variable template specialization might not have a VisibilityAttr attached to it while the template that it specializes does, in fact, have one. We should consider the template in such cases. This fixes PR19597. llvm-svn: 207498

* Check -Werror options during module validationBen Langmuir2014-04-299-12/+266
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch checks whether the diagnostic options that could lead to errors (principally -Werror) are consistent between when a module was built and when it is loaded. If there are new -Werror flags, then the module is rebuilt. In order to canonicalize the options we do this check at the level of the constructed DiagnosticsEngine, which contains the final set of diag to diagnostic level mappings. Currently we only rebuild with the new diagnostic options, but we intend to refine this in the future to include the union of the new and old flags, since we know the old ones did not cause errors. System modules are only rebuilt when -Wsystem-headers is enabled. One oddity is that unlike checking language options, we don’t perform this diagnostic option checking when loading from a precompiled header. The reason for this is that the compiler cannot rebuild the PCH, so anything that requires it to be rebuilt effectively leaks into the build system. And in this case, that would mean the build system understanding the complex relationship between diagnostic options and the underlying diagnostic mappings, which is unreasonable. Skipping the check is safe, because these options do not affect the generated AST. You simply won’t get new build errors due to changed -Werror options automatically, which is also true for non-module cases. llvm-svn: 207477
