2010-10-24Introduce a DeclsToRewrite field in ASTWrite, used for collecting the decls ↵Argyrios Kyrtzidis
that will be replaced in the chained PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117238 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-24Some method renaming, no functionality change.Argyrios Kyrtzidis
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117237 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-24Refactoring.Argyrios Kyrtzidis
- Pass around RecordDataImpl instead of the concrete RecordData so that any SmallVector can be used. - Move ASTDeclWriter::WriteCXXDefinitionData to ASTWriter::AddCXXDefinitionData. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117236 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-24Put the mechanism in place to track modifications in an AST entity that were ↵Argyrios Kyrtzidis
committed after its initial creation/deserialization and store the changes in a chained PCH. The idea is that the AST entities call methods on the ASTMutationListener to give notifications of changes; the PCHWriter implements the ASTMutationListener interface and stores the incremental changes of the updated entity. WIP git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@117235 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-21Reorganize predefined macros for all Windows targets.Michael J. Spencer
This adds an option to set the _MSC_VER macro without recompiling. This is very useful when testing compatibility with the Windows SDK and c++stdlib headers. -fmsc-version=<version> (defaults to VS2003 (1300)) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116999 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
2010-10-18Read/write declaration attributes from/to PCH properly. Embed them in the ↵Argyrios Kyrtzidis
declaration block instead of trying to create another block. The new block was messing with the assumption that after decls block comes the stmts block. Fixes http://llvm.org/PR8406 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116737 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-15Read/write to/from PCH DeclarationNameLocs, DeclarationNameInfos and ↵Argyrios Kyrtzidis
QualifierInfos (rdar://8513756). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116598 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Allow deserialization of just the fields of a record, when we want to ↵Argyrios Kyrtzidis
iterate over them, instead of deserializing the complete declaration context of the record. Iterating over the fields of a record is very common (e.g to determine the layout), unfortunately we needlessly deserialize every declaration that the declaration context of the record contains; this can be bad for large C++ classes that contain a lot of methods. Fix this by allow deserialization of just the fields when we want to iterate over them. Progress for rdar://7260160. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116507 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-14Eliminate usage of ObjCSuperExpr used forFariborz Jahanian
'super' as receiver of property or a setter/getter methods. //rdar: //8525788 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116483 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-05Fix a marvelous chained AST writing bug, where we end up with theDouglas Gregor
following amusing sequence: - AST writing schedules writing a type X* that it had never seen before - AST writing starts writing another declaration, ends up deserializing X* from a prior AST file. Now we have two type IDs for the same type! - AST writer tries to write X*. It only has the lower-numbered ID from the the prior AST file, so references to the higher-numbered ID that was scheduled for writing go off into lalaland. To fix this, keep the higher-numbered ID so we end up writing the type twice. Since this issue occurs so rarely, and type records are generally rather small, I deemed this better than the alternative: to keep a separate mapping from the higher-numbered IDs to the lower-numbered IDs, which we would end up having to check whenever we want to deserialize any type. Fixes <rdar://problem/8511624>, I think. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115647 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-04When a type comes from a previously-loaded PCH/AST file, don't try to write ↵Douglas Gregor
it into a chained PCH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115527 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-02Implement chained PCH support for the macro definitions stored withinDouglas Gregor
the "detailed" preprocessing record. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115417 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-01Implement the C++0x "trailing return type" feature, e.g.,Douglas Gregor
auto f(int) -> int from Daniel Wallin! (With a few minor bug fixes from me). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115322 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-01When an identifier that has a macro definition in the original PCHDouglas Gregor
file is somehow changed in a chained PCH file, make sure that we write out the macro definition. Fixes part of <rdar://problem/8499034>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@115259 91177308-0d34-0410-b5e6-96231b3b80d8

2010-09-27When chaining PCHs, only write PPRecords that don't come from PCH, and give ↵Sebastian Redl
them the correct IDs. Fixes a crash in XCode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114913 91177308-0d34-0410-b5e6-96231b3b80d8

no tests for the chain yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111881 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Fix an issue with writing to PCH another included PCH, introduced by the ↵Argyrios Kyrtzidis
"using an AST on-disk hash table for name lookup" commit. When including a PCH and later re-emitting to another PCH, the name lookup tables of DeclContexts may be incomplete, since we now lazily deserialize the visible decls of a particular name. Fix the issue by iterating over the un-deserialized visible decls and completing the lookup tables of DeclContexts before writing them out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111698 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Use the AST on-disk hash table for name lookup inside a DeclContext.Argyrios Kyrtzidis
*Huge* improvement over the amount of deserializing that we do for C++ lookup. e.g, if he have the Carbon header precompiled and include it on a file containing this: int x; these are the before/after stats: BEFORE: *** AST File Statistics: 578 stat cache hits 4 stat cache misses 548/30654 source location entries read (1.787695%) 15907/16501 types read (96.400223%) 53525/59955 declarations read (89.275291%) 33993/43525 identifiers read (78.099945%) 41516/51891 statements read (80.006165%) 77/5317 macros read (1.448185%) 0/6335 lexical declcontexts read (0.000000%) 1/5424 visible declcontexts read (0.018437%) AFTER using the on-disk table: *** AST File Statistics: 578 stat cache hits 4 stat cache misses 548/30654 source location entries read (1.787695%) 10/16501 types read (0.060602%) 9/59955 declarations read (0.015011%) 161/43525 identifiers read (0.369902%) 20/51891 statements read (0.038542%) 6/5317 macros read (0.112846%) 0/6335 lexical declcontexts read (0.000000%) 2/5424 visible declcontexts read (0.036873%) There's only one issue affecting mostly the precompiled preambles which I will address soon. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111636 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-20Refactoring; move the functionality of ASTWriter::GetOrCreateTypeID to the ↵Argyrios Kyrtzidis
more generic MakeTypeID template function which accepts a type and a function object that returns a TypeIdx. MakeTypeID is in PCHCommon.h so that it can be used by ASTReader too. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111634 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-20serialization::TypeID is used with or without qualifiers, both as index and ↵Argyrios Kyrtzidis
