2012-09-01Split library clangRewrite into clangRewriteCore and clangRewriteFrontend.Ted Kremenek
This is similar to how we divide up the StaticAnalyzer libraries to separate core functionality to what is clearly associated with Frontend actions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163050 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-22Adds a method overwriteChangedFiles to the Rewriter. This is implemented byManuel Klimek
first writing the changed files to a temporary location and then overwriting the original files atomically. Also adds a RewriterTestContext to aid unit testing rewrting logic in general. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@157260 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-18introduce a new CharSourceRange class, and enhance the diagnostics routinesChris Lattner
to use them instead of SourceRange. CharSourceRange is just a SourceRange plus a bool that indicates whether the range has the end character resolved or whether the end location is the start of the end token. While most of the compiler wants to think of ranges that have ends that are the start of the end token, the printf diagnostic stuff wants to highlight ranges within tokens. This is transparent to the diagnostic stuff. To start taking advantage of the new capabilities, you can do something like this: Diag(..) << CharSourceRange::getCharRange(Begin,End) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106338 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-15Introduce a new BufferResult class to act as the return type ofDouglas Gregor
SourceManager's getBuffer() (and similar) operations. This abstract can be used to force callers to cope with errors in getBuffer(), such as missing files and changed files. Fix a bunch of callers to use the new interface. Add some very basic checks for file consistency (file size, modification time) into ContentCache::getBuffer(), although these checks don't help much until we've updated the main callers (e.g., SourceManager::getSpelling()). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@98585 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

2008-04-14Change 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

2008-03-15Make 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
