2008-04-17class Preprocessor: Now owns the "predefines" char*; it deletes [] it in its ↵Ted Kremenek
dstor. clang.cpp: InitializePreprocessor now makes a copy of the contents of PredefinesBuffer and passes it to the preprocessor object. clang.cpp: DriverPreprocessorFactory now calls "InitializePreprocessor" instead of this being done in main(). html::HighlightMacros() now takes a PreprocessorFactory, allowing it to conjure up a new Preprocessor to highlight macros. class HTMLDiagnostics now takes a PreprocessorFactory* that it can use for html::HighlightMacros(). Updated clients of HTMLDiagnostics to use this new interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49875 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-16Make HighlightRange correctly handle multi-line ranges. This causes us to Chris Lattner
correctly handle multi-line comments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49827 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-16add a new HighlightRange API, it doesn't handle multiline rangesChris Lattner
yet, but it will soon... git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49825 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-16split syntax highlighting of macros from keywords and comments,Chris Lattner
allowing us to use a cheaper means to highlight keywords and making it so that comments won't foul up macro expansions. Start highlighting macro expansions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49779 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-16Add a mode of hackily syntax highlighting comments. This has a number ofChris Lattner
problems, including the fact that it doesn't work well with multi-line comments due to Ted's crazy table. However, that could be fixed, and it does work with single-line ones :). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49778 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-16In html::EscapeText, instead of going through the rewriter withChris Lattner
a SourceLocation to get a RewriteBuffer, poke the RewriteBuffer with an offset directly. THis is no faster, but results in cleaner code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49774 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-16speed up -emit-html in a release build by 6.5% by avoiding std::string.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49764 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Add a bunch of comments, move RewriteRope::MakeRopeString out of line.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49689 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14move a ton of code out of line, from RewriteRope.h -> RewriteRope.cppChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49664 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14remove ifdefsChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49651 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

2008-04-12move the DeltaTree implementation out of line, remove debugging printfs etc.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49591 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-12remove ifdefsChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49587 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
2008-04-08Don't expand tabs in EscapeText, but rather expand them when writing outTed Kremenek
the HTML file. This should reduce the amount of memory pressure on the rewriter for files that have a lot of tabs. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49406 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-06don't dereference hte end iterator when inserting at end of buffer.Chris Lattner
Patch by Cédric Venet! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49259 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-27Add html::EscapeText for std::string; use this function to escape text in ↵Ted Kremenek
message bubbles. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48884 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-19Minor speed tweak per Chris's suggestion: use &S[0] instead of S.c_str().Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48544 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-19Integrated some of Chris's comments; check for an empty string in InsertStrXXX()Ted Kremenek
before descending into the bowels of the Rewriter. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48541 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-19Moved generation of html header/footer with builtin CSS to the rewriter library.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48537 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-19Added InsertStrXXX/InsertCStrXXX methods to the Rewriter to provide a simplerTed Kremenek
interface to the rewriter when clients have NULL terminated strings or std::string. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48532 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-19More cleanups to HTML rewriter API: remove the InsertTag method; was too ↵Ted Kremenek
complicated and clients can achieve a cleaner design just by inserting tags directly. Reserve the "html" namespace for meta-level operations (e.g., escaping text, etc.) git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48524 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-18More HTML rewriter cleanups. Preliminary CSS support in code pretty-printing.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48518 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-18Some cleanups to the HTMLRewrite API. Added support for printing out lineTed Kremenek
numbers (more work to be done on aesthetics). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48512 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-18Modified "InsertTag" (HTML rewriter) to have an optional "OutermostTag" flag toTed Kremenek
indicate whether or not the new tag should be the outermost tag at the specified location (in the case that other tags have been inserted at the same spot). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48506 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-18Added the beginning of a set of rewriter functions for pretty-printing sourceTed Kremenek
code as HTML. Added a new driver option "--emit-html" to dump the source of the main input file as HTML. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@48505 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

2008-01-31add some helper methods for removing and replacing text, this makes theChris Lattner
rewriter more robust. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46622 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-31Make rewriter::inserttext return a bool to indicate if it failed.Chris Lattner
Add a RewriteTest::ReplaceStmt method to factor the 'checking for rewrite failed + emitting diagnostic if so' code. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46619 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43902 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-08significantly simplify the implementation of RewriteRope by changing theChris Lattner
implementation to be list<RopePiece> instead of vector<RopePiece*>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43901 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-08improve MakeRopeString to avoid doing a malloc for every 2-character string Chris Lattner
that gets inserted. This speeds up the rewriter another 10%. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43896 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-08Simplify interface to MakeRopeString.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43895 91177308-0d34-0410-b5e6-96231b3b80d8
2007-11-08Add a new RewriteRope data structure which is a smarter way to represent the ↵Chris Lattner
text backing a rewrite buffer than using an std::vector<char>. This class was hacked together very quickly and needs to be cleaned up, but it seems to work. It speeds up rewriting a a 7M file from 6.43s to 0.24s on my machine. The impl could also be made to be a lot more algorithmically sound. This produces identical output to using vector on this testcase, if it causes a problems or bugs are encountered, it can be disabled by changing the RewriteBuffer::Buffer typedef back. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43884 91177308-0d34-0410-b5e6-96231b3b80d8

2007-10-17Add new API to rewrite one stmt/expr with another.Chris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43101 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-16Add a new Rewriter::getRangeSize method.Chris Lattner
Rename SourceRange::Begin()/End() to getBegin()/getEnd() for consistency with other code. Start building the rewriter towards handling @encode. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43047 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-16Push the rewriter forward a bit more. Now it rewritesChris Lattner
#import to #include's as a test. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@43041 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-13another step forward in rewriter stuff. This still hasChris Lattner
some incredibly subtle details that I'm working on getting right. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42940 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
