2013-05-03[Preprocessor] For the MacroExpands preprocessor callback, also pass the ↵Argyrios Kyrtzidis
MacroArgs object that provides information about the argument tokens for a function macro. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@181065 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-24[preprocessor] Use MacroDirective in the preprocessor callbacks to make ↵Argyrios Kyrtzidis
available the full information about the macro (e.g if it was imported and where). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175978 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-22[preprocessing record] Have the MacroDefinitions map point to the ↵Argyrios Kyrtzidis
MacroDefinition object instead its index in the preprocessed entities vector. This is because the order of the entities in the vector can change in some (uncommon) cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@175907 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-08[libclang] Resolve a cursor that points to a macro name inside a #ifdef/#ifndefArgyrios Kyrtzidis
directive as a macro expansion. This is more of a "macro reference" than a macro expansion but it's close enough for libclang's purposes. If it causes issues we can revisit and introduce a new kind of cursor. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169666 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-04Refactor recording the preprocessor conditional directive regions out ofArgyrios Kyrtzidis
PreprocessingRecord and into its own class, PPConditionalDirectiveRecord. Decoupling allows a client to use the functionality of PPConditionalDirectiveRecord without needing a PreprocessingRecord. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169229 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-13More doxygen/documentation cleanups.James Dennett
This reduces the number of warnings generated by Doxygen by about 100 (roughly 10%). Issues addressed: (1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments when they're not supposed to be Doxygen commands or links, and similarly for "<baz>" when it's not intended as as HTML tag; (2) Changed some \t commands (which don't exist) to \c ("to refer to a word of code", as the Doxygen manual says); (3) \precondition becomes \pre; (4) When touching comments, deleted a couple of spurious spaces in them; (5) Changed some \n and \r to \\n and \\r; (6) Fixed one tiny typo: #pragms -> #pragma. This patch touches documentation/comments only. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@158422 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-27[preprocessor] Handle correctly inclusion directives that have macro ↵Argyrios Kyrtzidis
expansions, e.g "#include MACRO(STUFF)". -As an inclusion position for the included file, use the file location of the file where it was included but *after* the macro expansions. We want the macro expansions to be considered as before-in-translation-unit for everything in the included file. -In the preprocessing record take into account that only inclusion directives can be encountered as "out-of-order" (by comparing the start of the range which for inclusions is the hash location) and use binary search if there is an extreme number of macro expansions in the include directive. Fixes rdar://11111779 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@153527 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-09[AST/etc] Mark {getSourceRange(),getStartLoc(),getEndLoc()} as LLVM_READONLY.Daniel Dunbar
- The theory here is that we have these functions sprinkled in all over the place. This should allow the optimizer to at least realize it can still do load CSE across these calls. - I blindly marked all instances as such, even though the optimizer can infer this attribute in some instances (some of the inline ones) as that was easier and also, when given the choice between thinking and not thinking, I prefer the latter. You might think this is mere frivolity, but actually this is good for a .7 - 1.1% speedup on 403.gcc/combine.c, JSC/Interpreter.cpp, OGF/NSBezierPath-OAExtensions.m. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152426 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-05[preprocessor] Enhance PreprocessingRecord to keep track of locations of ↵Argyrios Kyrtzidis
conditional directives. Introduce PreprocessingRecord::rangeIntersectsConditionalDirective() which returns true if a given range intersects with a conditional directive block. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152018 91177308-0d34-0410-b5e6-96231b3b80d8
2012-02-25Don't record nested macro expansions in the preprocessing record,Argyrios Kyrtzidis
it can only bring pain when dealing with preprocessor abuse (see: boost). rdar://10898986 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@151427 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-25[PCH] When visiting preprocessed entities, make it possible to avoid ↵Argyrios Kyrtzidis
deserializing preprocessed entities that are #included in the range that we are interested. This is useful when we are interested in preprocessed entities of a specific file, e.g when we are annotating tokens. There is also an optimization where we cache the last result of PreprocessingRecord::getPreprocessedEntitiesInRange and we re-use it if there is a call with the same range as before. rdar://10313365 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@142887 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-19In libclang, when visiting preprocessed entities in a source range, useArgyrios Kyrtzidis
PreprocessingRecord's getPreprocessedEntitiesInRange. Also remove all the stuff that were added in ASTUnit that are unnecessary now that we do a binary search for preprocessed entities and deserialize only what is necessary. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140063 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-19Introduce PreprocessingRecord::getPreprocessedEntitiesInRange()Argyrios Kyrtzidis
which will do a binary search and return a pair of iterators for preprocessed entities in the given source range. Source ranges of preprocessed entities are stored twice currently in the PCH/Module file but this will be fixed in a subsequent commit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140058 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-15[PCH] Overhaul how preprocessed entities are [de]serialized.Argyrios Kyrtzidis
-Use an array of offsets for all preprocessed entities -Get rid of the separate array of offsets for just macro definitions; for references to macro definitions use an index inside the preprocessed entities array. -Deserialize each preprocessed entity lazily, at first request; not in bulk. Paves the way for binary searching of preprocessed entities that will offer efficiency and will simplify things on the libclang side a lot. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139809 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-21Rework the detailed preprocessing record to separate preprocessingDouglas Gregor
entities generated directly by the preprocessor from those loaded from the external source (e.g., the ASTReader). By separating these two sets of entities into different vectors, we allow both to grow independently, and eliminate the need for preallocating all of the loaded preprocessing entities. This is similar to the way the recent SourceManager refactoring treats FileIDs and the source location address space. As part of this, switch over to building a continuous range map to track preprocessing entities. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135646 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-20now that we have a centralized place to do so, add some using declarations forChris Lattner
some common llvm types: stringref and smallvector. This cleans up the codebase quite a bit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135576 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Move the rest of the preprocessor terminology from 'instantiate' andChandler Carruth
variants to 'expand'. This changed a couple of public APIs, including one public type "MacroInstantiation" which is now "MacroExpansion". The rest of the codebase was updated to reflect this, especially the libclang code. Two of the C++ (and thus easily changed) libclang APIs were updated as well because they pertained directly to the old MacroInstantiation class. No functionality changed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135139 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-06Introduce a new libclang parsing flag,Douglas Gregor
CXTranslationUnit_NestedMacroInstantiations, which indicates whether we want to see "nested" macro instantiations (e.g., those that occur inside other macro instantiations) within the detailed preprocessing record. Many clients (e.g., those that only care about visible tokens) don't care about this information, and in code that uses preprocessor metaprogramming, this information can have a very high cost. Addresses <rdar://problem/9389320>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130990 91177308-0d34-0410-b5e6-96231b3b80d8
2011-05-04Enhance clang_getCXTUResourceUsage() to return the amount of memory used by ↵Ted Kremenek

2011-04-26To be able to replay compilations we need to accurately remodel howManuel Klimek
includes get resolved, especially when they are found relatively to another include file. We also try to get it working for framework includes, but that part of the code is untested, as I don't have a code base that uses it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@130246 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

2010-11-30When using a precompiled preamble with detailed preprocessing records,Douglas Gregor
trap the serialized preprocessing records (macro definitions, macro instantiations, macro definitions) from the generation of the precompiled preamble, then replay those when walking the list of preprocessed entities. This eliminates a bug where clang_getCursor() wasn't able to find preprocessed-entity cursors in the preamble. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@120396 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.
