2009-08-19Convert parts of Rewriter to StringRef based API.Daniel Dunbar
- Please accept my sincere apologies for the gratuitous elimination of code duplication, manual string length counting, unnecessary strlen calls, etc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@79448 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-30Key decisions about 'bool' vs '_Bool' to be based on a new flag in langoptions.Chris Lattner
This is simple enough, but then I thought it would be nice to make PrintingPolicy get a LangOptions so that various things can key off "bool" and "C++" independently. This spiraled out of control. There are many fixme's, but I think things are slightly better than they were before. One thing that can be improved: CFG should probably have an ASTContext pointer in it, which would simplify its clients. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74493 91177308-0d34-0410-b5e6-96231b3b80d8
2009-05-18Fix for PR2386: distinguish between insertion and replacements in the Eli Friedman
delta tree. The issue is roughly a conflict in ReplaceText between two kinds of uses. One, it should be possible to replace a replacement: for example, the ObjC rewriter calls ReplaceStmt for an expression, then replaces the resulting expression with another expression. Two, it should be possible to replace text that already has text inserted before it: for example, the HTML rewriter inserts a bunch of tags at the beginning of the line, then tries to escape the first character on the line. This patch distinguishes the two cases by storing the deltas separately; essentially, replacements and insertions no longer interfere with each other. Another possibility would be to add some sort of flag to ReplaceText, but this seems a bit more intuitive and flexible. There are a few downsides to the current solution: one is that there isn't any way to remove/replace an insertion without touching additional surrounding text; if such an operation turns out to be useful, an additional method or flag can be added. Another is that an insertion and replacing a string of length zero are distinct operations; I'm not sure how to resolve this, or whether it will be confusing in practice. This is relatively sensitive code, so please test and tell me if anything breaks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@72000 91177308-0d34-0410-b5e6-96231b3b80d8
2009-04-14Change Lexer::MeasureTokenLength to take a LangOptions reference.Chris Lattner
This allows it to accurately measure tokens, so that we get: t.cpp:8:13: error: unknown type name 'X' static foo::X P; ~~~~~^ instead of the woefully inferior: t.cpp:8:13: error: unknown type name 'X' static foo::X P; ~~~~ ^ Most of this is just plumbing to push the reference around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@69099 91177308-0d34-0410-b5e6-96231b3b80d8
2009-01-26Check in the long promised SourceLocation rewrite. This lays theChris Lattner
ground work for implementing #line, and fixes the "out of macro ID's" problem. There is nothing particularly tricky about the code, other than the very performance sensitive SourceManager::getFileID() method. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@62978 91177308-0d34-0410-b5e6-96231b3b80d8
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

2008-10-03add a new Rewriter::getRewritenText method that returns the text for a rangeChris Lattner
that includes any edits in the range. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57037 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-13Patch by Csaba Hruska!Ted Kremenek
"Here is a patch what replaces std::ostream with llvm::raw_ostream. This patch covers the AST library, but ignores Analysis lib." git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56185 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-14Change the RewriteRope::Chunks data structure from an std::list intoChris Lattner
a nice shiny B+ Tree variant. This fixes the last of the known algorithmic issues with the rewriter, allowing a significant speedup. For example, -emit-html on Ted's 500K .i file speeds up from 26.8s -> 0.64s in a debug build (41x!) and 5.475s -> 0.132s (41x!) in an optimized build. This code is functional but needs to be cleaned up, ifdefs removed, better commented, and moved to a .cpp file. I plan to do this tomorrow. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49635 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-12Do an initial hack at replacing one of the incredibly inefficient Chris Lattner
(but simple!) datastructures in the rewriter with a more complex but more efficient one. This replaces the Deltas vector with a specialized BTree that makes delta lookups much more efficient. This speeds up -emit-html on a 500K .i file from 157.154 to 27.127 seconds on my machine (5.8x). While this code is functional, it isn't very pretty, I have much refactoring planned for it, and will remove the USE_VECTOR ifdef. Stay tuned. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49586 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-18Added variant of "InsertText" in the Rewriter to support inserting text bothTed Kremenek
*before* and after a specific location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48504 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-18Bug fix in RewriteBuffer::getMappedOffset: potentially multiple deltas Ted Kremenek
need to be skipped over when AfterInserts == true, as multiple deltas may share the same FileLoc. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48503 91177308-0d34-0410-b5e6-96231b3b80d8
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
