2011-04-15Add __has_feature(cxx_range_for) check for C++11 range-based for loop.Richard Smith
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129573 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-15C1X: implement generic selectionsPeter Collingbourne
As an extension, generic selection support has been added for all supported languages. The syntax is the same as for C1X. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@129554 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-25we can now claim to fully support the override control feature in C++0x.Anders Carlsson
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128281 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-16Add a 'RawPath' parameter to the PPCallbacks interface. This allowsChandler Carruth
clients to observe the exact path through which an #included file was located. This is very useful when trying to record and replay inclusion operations without it beind influenced by the aggressive caching done inside the FileManager to avoid redundant system calls and filesystem operations. The work to compute and return this is only done in the presence of callbacks, so it should have no effect on normal compilation. Patch by Manuel Klimek. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127742 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-15Create __has_feature(cxx_noexcept) and mark it as working.Sebastian Redl
Find out that our C++0x status has only one field for noexcept expression and specification together, and that it was accidentally already marked as fully implemented. This completes noexcept specification work. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@127701 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-02Provide an attribute, objc_method_family, to allow the inferred familyJohn McCall
of an Objective-C method to be overridden on a case-by-case basis. This is a higher-level tool than ns_returns_retained &c.; it lets users specify that not only does a method have different retain/release semantics, but that it semantically acts differently than one might assume from its name. This in turn is quite useful to static analysis. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126839 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-28Rename tok::eom to tok::eod.Peter Collingbourne
The previous name was inaccurate as this token in fact appears at the end of every preprocessing directive, not just macro definitions. No functionality change, except for a diagnostic tweak. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@126631 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-26Add __has_feature(cxx_reference_qualified_functions); update tests andDouglas Gregor
documentation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124322 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-26Clean up the C++0x __has_feature tests. Specifically:Douglas Gregor
- 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 :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124291 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-25Downgrade the error about rvalue references to an extension warningDouglas Gregor
and turn on __has_feature(cxx_rvalue_references). The core rvalue references proposal seems to be fully implemented now, pending lots more testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124169 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-19Variadic templates are fully implemented.Douglas Gregor
Turn on the __has_feature switch for variadic templates, document their completion, and put the ExtWarn into the c++0x-extensions warning group. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123854 91177308-0d34-0410-b5e6-96231b3b80d8
2011-01-15clean up some dead code around __has_include() processing code identified by ↵Chris Lattner
the ted-o-matic. rdar://8867482 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123522 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-15Fix diagnostic pragmas.Argyrios Kyrtzidis
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121873 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-20Revert r119838 "Don't warn for empty 'if' body if there is a macro that ↵Argyrios Kyrtzidis
expands to nothing" and use a better and more general approach, where NullStmt has a flag to indicate whether it was preceded by an empty macro. Thanks to Abramo Bagnara for the hint! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119887 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-19Don't warn for empty 'if' body if there is a macro that expands to nothing, e.g:Argyrios Kyrtzidis
if (condition) CALL(0); // empty macro but don't warn for empty body. Fixes rdar://8436021. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119838 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-12Make sure to always check the result ofDouglas Gregor
SourceManager::getPresumedLoc(), so that we don't try to make use of an invalid presumed location. Doing so can cause crashes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118885 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-30Make the deserialization of macro definitions lazy, so that we canDouglas Gregor
load identifiers without loading their corresponding macro definitions. This is likely to improve PCH performance slightly, and reduces deserialization stack depth considerably when using preprocessor metaprogramming. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117750 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-20Extend the preprocessing record and libclang with support forDouglas Gregor
inclusion directives, keeping track of every #include, #import, etc. in the translation unit. We keep track of the source location and kind of the inclusion, how the file name was spelled, and the underlying file to which the inclusion resolved. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116952 91177308-0d34-0410-b5e6-96231b3b80d8
