2010-12-23Change all self assignments X=X to (void)X, so that we can turn on aJeffrey Yasskin
new gcc warning that complains on self-assignments and self-initializations. Fix one bug found by the warning, in which one clang::OverloadCandidate constructor failed to initialize its FunctionTemplate member. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@122459 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
2010-12-09Don't crash when code-completing after "#include <". It would be farDouglas Gregor
better to actually produce a decent set of completions by checking the system include paths, but not today. Fixes PR8744. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@121431 91177308-0d34-0410-b5e6-96231b3b80d8
2010-11-19Several PPCallbacks take an SourceLocation + IdentifierInfo, ratherCraig Silverstein
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 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@119845 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
2010-11-06Add PPCallbacks for #if/#ifdef/etc.Craig Silverstein
The callback info for #if/#elif is not great -- ideally it would give us a list of tokens in the #if, or even better, a little parse tree. But that's a lot more work. Instead, clients can retokenize using Lexer::LexFromRawLexer(). Reviewed by nlewycky. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@118318 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
2010-10-19Really^2 fix <rdar://problem/8361834>, this time without crashing.Ted Kremenek
Now MICache is a linked list (per the FIXME), where we tradeoff between MacroInfo objects being in MICache and MIChainHead. MacroInfo objects in the MICache chain are already "Destroy()'ed", so they can be reused. When inserting into MICache, we need to remove them from the regular linked list so that they aren't destroyed more than once. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116869 91177308-0d34-0410-b5e6-96231b3b80d8

2010-10-19Really fix: <rdar://problem/8361834> MacroInfo::AddTokenToBody() leaks memoryTed Kremenek
The problem was not the management of MacroInfo objects, but that when we recycle them via the MICache the memory of the underlying SmallVector (within MacroInfo) was not getting released. This is because objects stashed into MICache simply are reused with a placement new, and never have their destructor called. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116862 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-19Simplify lifetime management of MacroInfo objects in Preprocessor by having ↵Ted Kremenek
the Preprocessor maintain them in a linked list of allocated MacroInfos. This requires only 1 extra pointer per MacroInfo object, and allows us to blow them away in one place. This fixes an elusive memory leak with MacroInfos (whose exact location I couldn't still figure out despite substantial digging). Fixes <rdar://problem/8361834>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116842 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-09When we parse a pragma, keep track of how that pragma was originallyDouglas Gregor
spelled (#pragma, _Pragma, __pragma). In -E mode, use that information to add appropriate newlines when translating _Pragma and __pragma into #pragma, like GCC does. Fixes <rdar://problem/8412013>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@113553 91177308-0d34-0410-b5e6-96231b3b80d8
