2008-03-15Make a major restructuring of the clang tree: introduce a top-levelChris Lattner
lib dir and move all the libraries into it. This follows the main llvm tree, and allows the libraries to be built in parallel. The top level now enforces that all the libs are built before Driver, but we don't care what order the libs are built in. This speeds up parallel builds, particularly incremental ones. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48402 91177308-0d34-0410-b5e6-96231b3b80d8

2008-01-24Don't add an extra line to the end of the buffer, it doesn't really exist.Chris Lattner

2007-12-29Don't attribute in file headers anymore. See llvmdev for theChris Lattner
discussion of this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45410 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-19Added storage of the FileID of the the main source file of a translation unitTed Kremenek
in SourceManager. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45225 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-18When serializing SourceManager, we now serialize out absolute pathsTed Kremenek
to serialized source files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45183 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-13Add hack to SourceManager to support missing source files duringTed Kremenek
deserialization. Eventually this should be replaced with a lazy-reading mechanism that only reads source files when they are needed by clients. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45007 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-10Added newline to end of file.Ted Kremenek

2007-12-05Removed dependence on including iostream (use llvm/Support/Streams.h instead).Ted Kremenek

2007-12-05Renamed SourceManager::Read to SourceManager::CreateAndRegister.Ted Kremenek
Now sourcemanager deserializer automatically self-registers itself with the deserializer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@44591 91177308-0d34-0410-b5e6-96231b3b80d8

2007-11-09change source location to have two bits for macros, trackingChris Lattner
whether the location is the start and/or end of an expansion. These are currently not set or used by anything. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43968 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-31Updated a comment to hopefully silence a Lattner warning.Ted Kremenek

2007-10-30Updated some comments.Ted Kremenek
Disabled assignments for ContentCache. Copy-ctor for ContentCache now has an assertion preventing it to be copied from an object that already has an allocated buffer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43526 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-30Removed SrcMgr::FileInfo and SrcMgr::InfoRec and replaced them with aTed Kremenek
single class: ContentCache. This simplifies the logic in SourceManager and makes the ownership of MemoryBuffers clearer. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43518 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-11Push the rewriting APIs along. Build a trivial client that replaces tabsChris Lattner
with x's for now. The APIs are all unimplemented, so it doesn't do anything yet! :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42868 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-12Removed clang solution file for VC++, which didn't work properly because of ↵Hartmut Kaiser
hard coded paths in the llvm project files. Changed windows detection to use LLVM pp constant. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@41878 91177308-0d34-0410-b5e6-96231b3b80d8

2007-08-02Increase the macro id cache to look up several recent entries, not just the ↵Chris Lattner
last one. This is important in insane cases like the one dannyb sent me recently: #define F0(a) void a(){} #define F1(a) F0(a##0) F0(a##1) F0(a##2) F0(a##3) F0(a##4) F0(a##5) F0(a##6) F0(a##7) #define F2(a) F1(a##0) F1(a##1) F1(a##2) F1(a##3) F1(a##4) F1(a##5) F1(a##6) F1(a##7) #define F3(a) F2(a##0) F2(a##1) F2(a##2) F2(a##3) F2(a##4) F2(a##5) F2(a##6) F2(a##7) #define F4(a) F3(a##0) F3(a##1) F3(a##2) F3(a##3) F3(a##4) F3(a##5) F3(a##6) F3(a##7) #define F5(a) F4(a##0) F4(a##1) F4(a##2) F4(a##3) F4(a##4) F4(a##5) F4(a##6) F4(a##7) #define F6(a) F5(a##0) F5(a##1) F5(a##2) F5(a##3) F5(a##4) F5(a##5) F5(a##6) F5(a##7) F6(f) cpp is great. :) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40715 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-24Use a smallstring instead of an std::string in FileChanged to avoid some ↵Chris Lattner
malloc traffic. This speeds up -E on xalancbmk by 2.4% git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40461 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-24check in an experiment that didn't work out, to allow for future investigation.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40460 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-24Add a cache to SourceManager to accellerate line # lookup. This is aChris Lattner
bottleneck for -E computation, because every token that starts a line needs to determine *which* line it is on (so -E mode can insert the appropriate vertical whitespace). This optimization improves this common case where it is striding through the line # table. This speeds up -E on xalancbmk by 3.2% git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40459 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-21Add support for reusing macroid's with negative physical loc deltas. ThisChris Lattner
keeps the MacroInfo table more compact. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40281 91177308-0d34-0410-b5e6-96231b3b80d8

2007-07-20improve comments, implement a trivial single-entry cache in Chris Lattner
SourceManager::getInstantiationLoc. With this change, every token expanded from a macro doesn't get its own MacroID. :) This reduces # macro IDs in carbon.h from 16805 to 9197 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40108 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-20Reimplement SourceLocation. Instead of having a Chris Lattner
fileid/offset pair, it now contains a bit discriminating between mapped locations and file locations. This separates the tables for macros and files in SourceManager, and allows better separation of concepts in the rest of the compiler. This allows us to have *many* macro instantiations before running out of 'addressing space'. This is also more efficient, because testing whether something is a macro expansion is now a bit test instead of a table lookup (which also used to require having a srcmgr around, now it doesn't). This is fully functional, but there are several refinements and optimizations left. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@40103 91177308-0d34-0410-b5e6-96231b3b80d8
2007-07-16Make octal constant lexing use AdvanceToTokenCharacter to give moreChris Lattner
accurate diagnostics. For test/Lexer/comments.c we now emit: int x = 000000080; /* expected-error {{invalid digit}} */ ^ constants.c:7:4: error: invalid digit '8' in octal constant 00080; /* expected-error {{invalid digit}} */ ^ The last line is due to an escaped newline. The full line looks like: int y = 0000\ 00080; /* expected-error {{invalid digit}} */ Previously, we emitted: constants.c:4:9: error: invalid digit '8' in octal constant int x = 000000080; /* expected-error {{invalid digit}} */ ^ constants.c:6:9: error: invalid digit '8' in octal constant int y = 0000\ ^ which isn't too bad, but the new way is better for the user, regardless of whether there is an escaped newline or not. All the other lexer-related diagnostics should switch over to using AdvanceToTokenCharacter where appropriate. Help wanted :). This implements test/Lexer/constants.c. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@39906 91177308-0d34-0410-b5e6-96231b3b80d8
