| | | | | | | deserialization. Eventually this should be replaced with a lazy-reading mechanism that only reads source files when they are needed by clients. llvm-svn: 45007
* Added newline to end of file.Ted Kremenek2007-12-101-1/+1
| | | | llvm-svn: 44797
* Removed dependence on including iostream (use llvm/Support/Streams.h instead).Ted Kremenek2007-12-051-9/+9

* Updated some comments.Ted Kremenek2007-10-301-5/+8
| | | | | | | | 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. llvm-svn: 43526
* Removed SrcMgr::FileInfo and SrcMgr::InfoRec and replaced them with aTed Kremenek2007-10-301-53/+42
| | | | | | | single class: ContentCache. This simplifies the logic in SourceManager and makes the ownership of MemoryBuffers clearer. llvm-svn: 43518

* Push the rewriting APIs along. Build a trivial client that replaces tabsChris Lattner2007-10-111-0/+7
| | | | | | | with x's for now. The APIs are all unimplemented, so it doesn't do anything yet! :) llvm-svn: 42868

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. :) llvm-svn: 40715

* check in an experiment that didn't work out, to allow for future investigation.Chris Lattner2007-07-241-5/+27
| | | | llvm-svn: 40460
* Add a cache to SourceManager to accellerate line # lookup. This is aChris Lattner2007-07-241-51/+96
| | | | | | | | | | | 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% llvm-svn: 40459
* Add support for reusing macroid's with negative physical loc deltas. ThisChris Lattner2007-07-211-4/+3

* improve comments, implement a trivial single-entry cache in Chris Lattner2007-07-201-2/+21
| | | | | | | | | 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 llvm-svn: 40108
* Reimplement SourceLocation. Instead of having a Chris Lattner2007-07-201-54/+20
| | | | | | | | | | | | | | | | | 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. llvm-svn: 40103
* Make octal constant lexing use AdvanceToTokenCharacter to give moreChris Lattner2007-07-161-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 39906

| | | | | | (needed on Solaris) llvm-svn: 39781
* Finally bite the bullet and make the major change: split the clang namespaceChris Lattner2007-06-151-1/+1
| | | | | | | | | | | | | out of the llvm namespace. This makes the clang namespace be a sibling of llvm instead of being a child. The good thing about this is that it makes many things unambiguous. The bad things is that many things in the llvm namespace (notably data structures like smallvector) now require an llvm:: qualifier. IMO, libsystem and libsupport should be split out of llvm into their own namespace in the future, which will fix this issue. llvm-svn: 39659
