2009-01-17this massive patch introduces a simple new abstraction: it makesChris Lattner
"FileID" a concept that is now enforced by the compiler's type checker instead of yet-another-random-unsigned floating around. This is an important distinction from the "FileID" currently tracked by SourceLocation. *That* FileID may refer to the start of a file or to a chunk within it. The new FileID *only* refers to the file (and its #include stack and eventually #line data), it cannot refer to a chunk. FileID is a completely opaque datatype to all clients, only SourceManager is allowed to poke and prod it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62407 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-15IdentifierInfo:Ted Kremenek
- IdentifierInfo can now (optionally) have its string data not be co-located with itself. This is for use with PTH. This aspect is a little gross, as getName() and getLength() now make assumptions about a possible alternate representation of IdentifierInfo. Perhaps we should make IdentifierInfo have virtual methods? IdentifierTable: - Added class "IdentifierInfoLookup" that can be used by IdentifierTable to perform "string -> IdentifierInfo" lookups using an auxilliary data structure. This is used by PTH. - Perform tests show that IdentifierTable::get() does not slow down because of the extra check for the IdentiferInfoLookup object (the regular StringMap lookup does enough work to mitigate the impact of an extra null pointer check). - The upshot is that now that some IdentifierInfo objects might be owned by the IdentiferInfoLookup object. This should be reviewed. PTH: - Modified PTHManager::GetIdentifierInfo to *not* insert entries in IdentifierTable's string map, and instead create IdentifierInfo objects on the fly when mapping from persistent IDs to IdentifierInfos. This saves a ton of work with string copies, hashing, and StringMap lookup and resizing. This change was motivated because when processing source files in the PTH cache we don't need to do any string -> IdentifierInfo lookups. - PTHManager now subclasses IdentifierInfoLookup, allowing clients of IdentifierTable to transparently use IdentifierInfo objects managed by the PTH file. PTHManager resolves "string -> IdentifierInfo" queries by doing a binary search over a sorted table of identifier strings in the PTH file (the exact algorithm we use can be changed as needed). These changes lead to the following performance changes when using PTH on Cocoa.h: - fsyntax-only: 10% performance improvement - Eonly: 30% performance improvement git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62273 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-14Fix typo and spelling of -Wunused-macros.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62239 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-13Add an initial framework of a DeclContextPrinter. It can print DeclContext andZhongxing Xu
its Decls in indented format. An Example: $ cat t.cpp class A { int a; void f(); }; void A::f() { a = 3; } $ clang -print-decl-contexts t.cpp [translation unit] 0x9754d7c <typedef> __builtin_va_list [class] A 0x9753310 <class> A 0x975ce20 <field> a <c++ method> f <c++ ctor> A <c++ ctor> A <c++ method> operator= <c++ dtor> ~A [c++ method] f [[0x9753310]] Some comments: '<>' indicates a declaration, '[]' indicates a definition, '[[ ]]' displays the semantic DeclContext which is different from the lexical DeclContext. The symbols printed can definitely be changed in the future. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62136 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-12Implement support for anonymous structs and unions in C. Both C andDouglas Gregor
C++ handle anonymous structs/unions in the same way. Addresses several bugs: <rdar://problem/6259534> <rdar://problem/6481130> <rdar://problem/6483159> The test case in PR clang/1750 now passes with -fsyntax-only, but CodeGen for inline assembler still fails. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62112 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-09Always print out SourceManager stats with 'Stats' is true. This revealed ↵Ted Kremenek
that PTH always pulls in the source pages with -fsyntax-only (investigating further). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61996 91177308-0d34-0410-b5e6-96231b3b80d8

2009-01-06Remove redunant (and incorrect) call to SourceManager::PrintStats(). This ↵Ted Kremenek
would be called after a SourceManager was 'cleared', so it printed bogus results. Moreover, these stats are already printed earlier in the code path. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@61825 91177308-0d34-0410-b5e6-96231b3b80d8

2008-12-05-std=c99 defaults blocks to off even on darwin, but -fblocks overridesChris Lattner
even it. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60568 91177308-0d34-0410-b5e6-96231b3b80d8
2008-12-04instead of forcing blocks on by default, make them default to off, but letChris Lattner
specific targets default them to on. Default blocks to on on 10.6 and later. Add a -fblocks option that allows the user to override the target's default. Use -fblocks in the various testcases that use blocks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60563 91177308-0d34-0410-b5e6-96231b3b80d8

2008-11-26Implement implicit conversions for Objective-C specific types, e.g., Douglas Gregor
converting a pointer to one Objective-C interface into a pointer to another Objective-C interface, and conversions with 'id'. The semantics seems to match GCC, although they seem somewhat ad hoc. Fixed a few cases where we assumed the C++ definition of isObjectType, but were getting the C definition, causing failures in trouble with conversions to void pointers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@60130 91177308-0d34-0410-b5e6-96231b3b80d8
