2008-04-16Switch AddLineNumbers to hack on a rewritebuffer instead of on a Chris Lattner
rewriter, getting sourcelocations out of the picture. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49775 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
2008-04-16Remove uses of "Selector&" and "const Selector&", since Selector is just anTed Kremenek
immutable smart pointer (we don't need to pass references, just pass Selector). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49773 91177308-0d34-0410-b5e6-96231b3b80d8

speeds up -emit-html on ted's testcase by 29% (.138 -> 0.107s) in a release build. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49767 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-15Added initial boilerplate to support toll-free bridging in the ref-count ↵Ted Kremenek
checker. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49756 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Added some comments to GRExprEngine. Reorder some of the method definitionsTed Kremenek
to start logically organizing them. Added initial plug-in transfer function support for Objective-C message expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49752 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Change "VisitBlockVarDecl" to "VisitVarDecl". UninitializedValues now worksTed Kremenek
as before r49748 (where BlockVarDecl was removed). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49749 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Remove FileVarDecl and BlockVarDecl. They are replaced by ↵Steve Naroff
VarDecl::isBlockVarDecl() and VarDecl::isFileVarDecl(). This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests. I also have a couple FIXME's in UninitializedValues.cpp. Ted, can you take a look? If the bug isn't obvious, I am happy to dig in and fix it (since I broke it). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49748 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-15Fix bug in terminator processing for uninitialized-values: simply ignore the ↵Ted Kremenek
terminator, don't reprocess it. LiveVariables analysis now does a flow-insensitive analysis to determine what variables have their address taken; these variables are now always treated as being live. The DataflowSolver now uses "SetTopValue()" when getting the initial value for the entry/exit block. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49734 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49711 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Added initial support into the flow-sensitive dataflow solver to visit the ↵Ted Kremenek
Block-level expression in a block's terminator. This expression is visited within a block, but it is accessed by the terminator. This is important to observe because for live-variables analysis the block-level expression is live between the terminator and where the expression occurs in the block. So far this hasn't been an issue to not observe this because the block-level expression used in the terminator is always the last one in the block, and we have never queried the liveness information about this point (but before the terminator). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49709 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-14simplify the implementation of the insert/split operation to returnChris Lattner
the new RHS directly instead of indirecting through the 'InsertResult' struct. This eliminates InsertResult. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49694 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-14Fix regression in Diagnostic that caused it to not register the numberTed Kremenek
of errors. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49686 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Added "getCanonicalID()", "isFromSameFile", and "isFromMainFile" to compareTed Kremenek
the files of different SourceLocations. These methods correctly handle the case where a file may have multiple FileIDs due to it being large enough to be spread across several chunks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49682 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-14Hooked up the dead-store checker to the BugReporter interface. Now dead-storeTed Kremenek
warnings are emitted as part of the warnings registered by GRSimpleVals. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49658 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

2008-04-13This patch adds very basic support for parsing and type-checking classDouglas Gregor
inheritance in C++. It'll parse the base-specifier list, e.g., class D : public B1, virtual public B2 { }; and do some of the simpler semantic checks (B1 and B2 are classes; they aren't unions or incomplete types, etc). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49623 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-13This patch is just the easy part of the class names patch, whichChris Lattner
allows the parsing of "class" in addition to "struct" and "union" to declare a record. So this patch allows: class C { }; class C c1; But it does not contain the lookup bits, so this won't work yet: C c2; Patch by Doug Gregor! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49613 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-13Change the btree algorithm to split nodes bottom-up instead of top-down.Chris Lattner
This results in an (IMO) simpler algorithm, results in fewer splits, and is more amenable to delta handling (there is no reason to mutate the tree at all when adding a delta to a position that already exists in the tree). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49609 91177308-0d34-0410-b5e6-96231b3b80d8
