2009-04-27Load most of the source manager's information lazily from the PCHDouglas Gregor
file. In particular, only eagerly load source location entries for files and for the predefines buffer. Other buffers and macro-instantiation source location entries are loaded lazily. With the Cocoa-prefixed "Hello, World", we only load 815/26555 source location entities. This halves the amount of user time we spend in this "Hello, World" program with -fsyntax-only (down to .007s). This optimization is part 1 of 2 for the source manager. This eliminates most of the user time in loading a PCH file. We still spend too much time initialize File structures (especially in the calls to stat), so we need to either make the loading of source location entries for files lazy or import the stat cache from the PTH implementation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70196 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-26Some fixes for PCH (de-)serialization of Objective-C AST nodes:Douglas Gregor
- Deal with the Receiver/ClassInfo shared storage in ObjCMessageExpr - Implement PCH support for ImplicitParamDecl - Fix the handling of the body of an ObjCMethodDecl - Several cast -> cast_or_null fixes - Make Selector::getIdentifierInfoForSlot work for 1-argument, NULL selectors. - Make Selector::getAsString() work with NULL selectors. - Fix the names of VisitObjCAtCatchStmt and VisitObjCAtFinallyStmt in the PCH reader and writer; these were never getting called. At this point, all of the pch-test tests pass for C and Objective-C. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70163 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-26implement PCH support for the rest of ExprObjC.h, includingChris Lattner
the missing bits of ObjCMessageExpr. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70100 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-26Don't read all of the records in the PCH file's preprocessor block,Douglas Gregor
most of which are ignored. Instead, move the __COUNTER__ value out to a PCH-level record (since it is handled eagerly) and move the header file information into the SourceManager block (which is also, currently, loaded eagerly). This results in another 17% performance improvement in the Cocoa-prefixed "Hello, World" with PCH. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70097 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Load the selector table lazily from the PCH file. Douglas Gregor
This results in a 10% speedup on the Cocoa-prefixed "Hello, World!", all of which is (not surprisingly) user time. There was a tiny reduction in the size of the PCH file for Cocoa.h, because certain selectors aren't being written twice. I'm using two new tricks here that I'd like to replicate elsewhere: (1) The selectors not used in the global method pool are packed into the blob after the global method pool's on-disk hash table and stored as keys, so that all selectors are in the same blob. (2) We record the offsets of each selector key when we write it into the global method pool (or after it, in the same blob). The offset table is written as a blob, so that we don't need to pack/unpack a SmallVector with its contents. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@70055 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-25Add PCH support for ObjCMessageExpr (needed to build Mail).Steve Naroff

2009-04-24PCH support for the global method pool (= instance and factory methodDouglas Gregor
pools, combined). The methods in the global method pool are lazily loaded from an on-disk hash table when Sema looks into its version of the hash tables. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69989 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-23PCH support for all of the predefined Objective-C types, such as id,Douglas Gregor
SEL, Class, Protocol, CFConstantString, and __objcFastEnumerationState. With this, we can now run the Objective-C methods and properties PCH tests. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69932 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-23Add PCH read/write support for Objective-C Selectors.Steve Naroff
Note: This support is non-lazy. Once we get "Cocoa.h" humming, we can optimize this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69884 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-22Support tentative definitions in precompiled headers. This isn't likelyDouglas Gregor
to happen (ever), but at least we'll do the right thing when it does. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69829 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-22add three new objc expression types. @selector doesn't work because we have no Chris Lattner
way to serialize selectors yet. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69780 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-22implement serialization support for @encode,Chris Lattner
fix a couple of bugs in reader support for ObjCInterfaceDecl, and add support for reading ObjCInterfaceType. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69779 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-21Lazy deserialization of macro definitions for precompiled headers.Douglas Gregor
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%) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69755 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-21Add pch reader/writer support for most of DeclObjC.h. Very close to ↵Steve Naroff
reading/writing all ObjC AST nodes that we will encounter in header files (still a few FIXME's). Once selector support is in place, we should be able to take this for a spin (and add test cases). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69674 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-20Add pch reader/writer support for ObjCContainerDecl, ObjCInterfaceDecl, & ↵Steve Naroff
ObjCIvarDecl. Next step: Add selector support to PCHWriter::AddDeclarationName(). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69619 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-20Add pch reader/writer support for ObjCMethodDecl.Steve Naroff
Test will be enabled with ObjCInterfaceDecl is added. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69594 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-18Store the type ID for __builtin_va_list in the PCH file, so that theDouglas Gregor
AST context's __builtin_va_list type will be set when the PCH file is loaded. This fixes the crash when CodeGen'ing a va_arg expression pulled in from a PCH file. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69421 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-17Keep track of the number of statements/expressions written to and readDouglas Gregor
from a PCH file. It turns out that "Hello, World!" is bringing in 19% of all of the statements in Carbon.h, so we need to be lazy. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69393 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-17PCH support for inline assembly statements.Douglas Gregor
This completes support for all of C (+ extensions). We can (again) build a PCH file for Carbon.h. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69385 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-14Add PCH support for ImplicitCastExprs. This is the first expressionDouglas Gregor
kind PCH handles that has an expression as an operand, so most of this work is in the infrastructure to rebuild expression trees from the serialized representation.
