2011-07-25Mechanically rename SourceManager::getInstantiationLoc andChandler Carruth
FullSourceLoc::getInstantiationLoc to ...::getExpansionLoc. This is part of the API and documentation update from 'instantiation' as the term for macros to 'expansion'. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135914 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
2011-07-19Revamp the SourceManager to separate the representation of parsedDouglas Gregor
source locations from source locations loaded from an AST/PCH file. Previously, loading an AST/PCH file involved carefully pre-allocating space at the beginning of the source manager for the source locations and FileIDs that correspond to the prefix, and then appending the source locations/FileIDs used for parsing the remaining translation unit. This design forced us into loading PCH files early, as a prefix, whic has become a rather significant limitation. This patch splits the SourceManager space into two parts: for source location "addresses", the lower values (growing upward) are used to describe parsed code, while upper values (growing downward) are used for source locations loaded from AST/PCH files. Similarly, positive FileIDs are used to describe parsed code while negative FileIDs are used to file/macro locations loaded from AST/PCH files. As a result, we can load PCH/AST files even during parsing, making various improvemnts in the future possible, e.g., teaching #include <foo.h> to look for and load <foo.h.gch> if it happens to be already available. This patch was originally written by Sebastian Redl, then brought forward to the modern age by Jonathan Turner, and finally polished/finished by me to be committed. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135484 91177308-0d34-0410-b5e6-96231b3b80d8

macros in libclang. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135148 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14NestedMacroInstantiations -> NestedMacroExpansionsChandler Carruth
This is switches all the interfaces points (and most of the commenst / local variables I saw on my way through) regarding the NestedMacroInstantiations bit. The libclang enums corresponding to this state were renamed, but a legacy enum was added with the old name, and the same value to keep existing clients working. I've added a documentation blurb for it, but let me know if there is a canonical way to document legacy elemenst of the libclang interface. No functionality changed here, even in tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135141 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-14Update all of the libclang code corresponding to the preprocessorChandler Carruth
MacroInstantiation -> MacroExpansion rename. Internally, everything is switched. Introduce a new cursor kind enum with the new name, but retain the old name as an alias so that we don't break backwards compatibility. Also update the debug printing routine to use 'macro expansions' as its explicitly not guaranteed to be stable, and mechanically switch the test cases over to that. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@135140 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

2011-07-09[arcmt] Introduce new '-ccc-arcmt-migrate <path>' ARC migration driver option.Argyrios Kyrtzidis
This is a new mode of migration, where we avoid modifying the original files but we emit temporary files instead. <path> will be used to keep migration process metadata. Currently the temporary files that are produced are put in the system's temp directory but we can put them in the <path> if is necessary. Also introduce new ARC migration functions in libclang whose only purpose, currently, is to accept <path> and provide pairs of original file/transformed file to map from the originals to the files after transformations are applied. Finally introduce the c-arcmt-test utility that exercises the new libclang functions, update arcmt-test, and add tests for the whole process. rdar://9735086. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134844 91177308-0d34-0410-b5e6-96231b3b80d8

2011-06-21Introduce a new AST node describing reference binding to temporaries.Douglas Gregor
MaterializeTemporaryExpr captures a reference binding to a temporary value, making explicit that the temporary value (a prvalue) needs to be materialized into memory so that its address can be used. The intended AST invariant here is that a reference will always bind to a glvalue, and MaterializeTemporaryExpr will be used to convert prvalues into glvalues for that binding to happen. For example, given const int& r = 1.0; The initializer of "r" will be a MaterializeTemporaryExpr whose subexpression is an implicit conversion from the double literal "1.0" to an integer value. IR generation benefits most from this new node, since it was previously guessing (badly) when to materialize temporaries for the purposes of reference binding. There are likely more refactoring and cleanups we could perform there, but the introduction of MaterializeTemporaryExpr fixes PR9565, a case where IR generation would effectively bind a const reference directly to a bitfield in a struct.

2011-05-27Objective-C doesn't consider the use of incomplete types as methodDouglas Gregor
parameter types to be ill-formed. However, it relies on the completeness of method parameter types when producing metadata, e.g., for a protocol, leading IR generating to crash in such cases. Since there's no real way to tighten down the semantics of Objective-C here without breaking existing code, do something safe but lame: suppress the generation of metadata when this happens.
