2009-04-23Eliminate Sema::ObjCProtocols. Instead, we place ObjCProtocolDecls inDouglas Gregor
their own namespace (IDNS_Protocol) and use the normal name-lookup routines to find them. Aside from the simplification this provides (one less DenseMap!), it means that protocols will be lazily deserialized from PCH files. Make the code size of the selector table block match the code size of the type and decl blocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69939 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-23the logic for computing __func__ and friends is really broken:Chris Lattner
the type assigned by sema (and is visible with sizeof(__func__) for example) has nothing to do with what codegen ends up producing. We should eventually add a method on PredefinedExpr to handle this.

2009-04-23Eliminate the three SmallVectors in ObjCImplDecl (for instanceDouglas Gregor
methods, class methods, and property implementations) and instead place all of these entities into the DeclContext.

in a bunch of declarations from the PCH file. We're down to loading very few declarations in Carbon-prefixed "Hello, World!": *** PCH Statistics: 6/20693 types read (0.028995%) 7/59230 declarations read (0.011818%) 50/44914 identifiers read (0.111324%) 0/32954 statements read (0.000000%) 5/6187 macros read (0.080815%) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69825 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-22Minimize the number and kind of "external definitions" that the PCHDouglas Gregor
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%) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69820 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-22Lazy loading of builtins for precompiled headers.Douglas Gregor
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%) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69815 91177308-0d34-0410-b5e6-96231b3b80d8
