| | | | | | | | | | | good for uniformity is good for PCH (or is it the other way around?). As part of this, make ObjCImplDecl inherit from NamedDecl (since ObjCImplementationDecls now need to have names so that they can be found). This brings ObjCImplDecl very, very close to ObjCContainerDecl; we may be able to merge them soon. llvm-svn: 69941

* Sema::ActOnStartClassInterface(): Use PushOnScopeChains().Steve Naroff2009-04-231-1/+1
| | | | | | This enables class recognition to work with PCH. I believe this means we can remove Sema::ObjCInterfaceDecls and it's usage within Sema::LookupName(). Will investigate. llvm-svn: 69891
* Add PCH read/write support for Objective-C Selectors.Steve Naroff2009-04-231-5/+104
| | | | | Note: This support is non-lazy. Once we get "Cocoa.h" humming, we can optimize this. llvm-svn: 69884

* Minimize the number and kind of "external definitions" that the PCHDouglas Gregor2009-04-221-3/+20
| | | | | | | | | | | | | | | | | | | | | | | file needs to store. CodeGen needs to see these definitions (via HandleTopLevelDecl), otherwise it won't be able to generate code for them. This patch notifies the consumer (e.g., CodeGen) about function definitions and variable definitions when the corresponding declarations are deserialized. Hence, we don't eagerly deserialize the declarations for every variable or function that has a definition in the PCH file. This gives another 5% speedup for the Carbon-prefixed "Hello, World!", and brings our PCH statistics down to something far more reasonable: *** PCH Statistics: 13/20693 types read (0.062823%) 17/59230 declarations read (0.028702%) 54/44914 identifiers read (0.120230%) 0/32954 statements read (0.000000%) 5/6187 macros read (0.080815%) llvm-svn: 69820
* Lazy loading of builtins for precompiled headers.Douglas Gregor2009-04-221-3/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PCH files now contain complete information about builtins, including any declarations that have been synthesized as part of building the PCH file. When using a PCH file, we do not initialize builtins at all; when needed, they'll be found in the PCH file. This optimization translations into a 9% speedup for "Hello, World!" with Carbon.h as a prefix header and roughly a 5% speedup for 403.gcc with its prefix header. We're also reading less of the PCH file for "Hello, World!": *** PCH Statistics: 286/20693 types read (1.382110%) 1630/59230 declarations read (2.751984%) 764/44914 identifiers read (1.701029%) 1/32954 statements read (0.003035%) 5/6187 macros read (0.080815%) down from *** PCH Statistics: 411/20693 types read (1.986179%) 2553/59230 declarations read (4.310316%) 1093/44646 identifiers read (2.448148%) 1/32954 statements read (0.003035%) 21/6187 macros read (0.339421%) llvm-svn: 69815

* Lazy deserialization of macro definitions for precompiled headers.Douglas Gregor2009-04-211-43/+108
| | | | | | | | | | | | | | | This optimization improves performance on the Carbon-prefixed "Hello, World!" example by 57%. For reference, we're now about 2.25x faster than GCC PCH. We're also pulling in far less of the PCH file: *** PCH Statistics: 411/20693 types read (1.986179%) 2553/59230 declarations read (4.310316%) 1093/44646 identifiers read (2.448148%) 1/32954 statements read (0.003035%) 21/6187 macros read (0.339421%) llvm-svn: 69755
* Lazy deserialization of the declaration chains associated withDouglas Gregor2009-04-211-39/+224
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | identifiers from a precompiled header. This patch changes the primary name lookup method for entities within a precompiled header. Previously, we would load all of the names of declarations at translation unit scope into a large DenseMap (inside the TranslationUnitDecl's DeclContext), and then perform a special "last resort" lookup into this DeclContext when we knew there was a PCH file (see Sema::LookupName). Now, when we see an identifier named for the first time, we load all of the declarations with that name that are visible from the translation unit into the IdentifierInfo's chain of declarations. Thus, the explicit "look into the translation unit's DeclContext" code is gone, and Sema effectively uses the same IdentifierInfo-based name lookup mechanism whether we are using a PCH file or not. This approach should help PCH scale with the size of the input program rather than the size of the PCH file. The "Hello, World!" application with Carbon.h as a PCH file now loads 20% of the identifiers in the PCH file rather than 85% of the identifiers. 90% of the 20% of identifiers loaded are actually loaded when we deserialize the preprocessor state. The next step is to make the preprocessor load macros lazily, which should drastically reduce the number of types, declarations, and identifiers loaded for "Hello, World". llvm-svn: 69737

* Write the identifier table into the PCH file as an on-disk hash tableDouglas Gregor2009-04-201-2/+3
| | | | | | | | | | | that also includes the contents of the IdentifierInfo itself (the various fields and flags, along with the chain of identifiers visible at the top level that have that name). We don't make any use of the hash table yet, except that our identifier ID -> string mapping points into the hash table now. llvm-svn: 69625

| | | | | | | | | | "Hello, World!", this takes us from deserializing 6469 statements/expressions down to deserializing 1 statement/expression. It only translated into a 1% improvement on the Carbon-prefixed 403.gcc, but (a) it's the right thing to do, and (b) we expect this to matter more once we lazily deserialize identifiers. llvm-svn: 69407
