* Clean up the C++0x __has_feature tests. Specifically:Douglas Gregor2011-01-261-10/+11
| | | | | | | | | | | | | - Don't publicize a C++0x feature through __has_feature if we aren't in C++0x mode (even if the feature is available only with a warning). - "auto" is not implemented well enough for its __has_feature to be turned on. - Fix the test of C++0x __has_feature to actually test what we're trying to test. Searching for the substring "foo" when our options are "foo" and "no_foo" doesn't work :) llvm-svn: 124291
* Downgrade the error about rvalue references to an extension warningDouglas Gregor2011-01-251-2/+2
| | | | | | | | and turn on __has_feature(cxx_rvalue_references). The core rvalue references proposal seems to be fully implemented now, pending lots more testing. llvm-svn: 124169

* Fix diagnostic pragmas.Argyrios Kyrtzidis2010-12-156-22/+40
| | | | | | | | | | | | Diagnostic pragmas are broken because we don't keep track of the diagnostic state changes and we only check the current/latest state. Problems manifest if a diagnostic is emitted for a source line that has different diagnostic state than the current state; this can affect a lot of places, like C++ inline methods, template instantiations, the lexer, etc. Fix the issue by having the Diagnostic object keep track of the source location of the pragmas so that it is able to know what is the diagnostic state at any given source location. Fixes rdar://8365684. llvm-svn: 121873
* Don't crash when code-completing after "#include <". It would be farDouglas Gregor2010-12-091-0/+6

* Revert r119838 "Don't warn for empty 'if' body if there is a macro that ↵Argyrios Kyrtzidis2010-11-201-1/+1

* Several PPCallbacks take an SourceLocation + IdentifierInfo, ratherCraig Silverstein2010-11-192-9/+9
| | | | | | | | | | | than a Token that holds the same information all in one easy-to-use package. There's no technical reason to prefer the former -- the information comes from a Token originally -- and it's clumsier to use, so I've changed the code to use tokens everywhere. Approved by clattner llvm-svn: 119845
* Don't warn for empty 'if' body if there is a macro that expands to nothing, e.g:Argyrios Kyrtzidis2010-11-191-0/+1
