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

2010-08-24AST writer support for having specializations of templates from earlier in ↵Sebastian Redl
the chain. This ought to finish C++ chained PCH support. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111986 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-24Remove a header dependency from Sema.h at the cost of some type safety.John McCall

2010-08-24Write visible update blocks. No regressions in normal PCH functionality, but ↵Sebastian Redl
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
2010-08-20Introduce the mechanism for building an AST on-disk hash table for name ↵Argyrios Kyrtzidis
lookup inside a DeclContext but don't use it yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111635 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

2010-08-20A bit of refactoring; Introduce ASTWriter::GetOrCreateTypeIdx and move the ↵Argyrios Kyrtzidis
emission of types there. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111632 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-20serialization::TypeID is used with or without qualifiers, both as index and ↵Argyrios Kyrtzidis
as index + qualifiers. Disambiguate and provide some type safety by using a new class TypeIdx for the "TypeID as index" semantics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111630 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-20Share the common code of ComputeHash(Selector Sel) instead of keeping 2 ↵Argyrios Kyrtzidis
copies in PCHReader and PCHWriter. No functionality change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111629 91177308-0d34-0410-b5e6-96231b3b80d8
