2008-04-15Revert my previous patch.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49751 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Remove dispatch to "VisitParmVarDecl".Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49750 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

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49742 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Added "summary table" to generated index.html page that allows one toTed Kremenek
toggle which bug reports are displayed in the report table. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49738 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

2008-04-15Improve dead store diagnostic.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49711 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-15Bug fix in VisitChildren: Only visit the last statement in a StmtExpr and ↵Ted Kremenek
the RHS of a comma expression, as the other Stmts will be visited elsewhere in a CFGBlock. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49710 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
2008-04-15Bug fix in dead stores: don't always check the liveness of the first declTed Kremenek
in a DeclStmt. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49708 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-15Bug fix in LiveVariables: Operators ++/-- may kill a value, but the variableTed Kremenek
is still live. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49705 91177308-0d34-0410-b5e6-96231b3b80d8

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

2008-04-14Use isFromMainFile instead of comparing FileIDs directly.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49687 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
2008-04-14Use SourceManager::isFromMainFile()Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49685 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Convert over to new SourceManager::isFromMainFile() instead of doing directTed Kremenek
FileID comparison (fixes insidious corner case with chunks). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49684 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14HTMLDiagnostics now uses the new "getCanonicalID()", "isFromMainFileID()" ↵Ted Kremenek
methods from SourceManager when doing HTML pretty-printing. This resolves an insidious bug when presenting error reports that only occurred in large source files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49683 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

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49678 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Only increment the number of diagnostics when the DiagnosticClient usedTed Kremenek
is the one attached to the Diagnostic object. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49677 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Added driver option "-checker-opt-analyze-headers" to force the staticTed Kremenek
analyzer to analyze functions declared in header files. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49675 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49668 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-14Bug fix in dead-store checker when walking the Decls in a DeclStmt: don'tTed Kremenek
assume that DeclStmts only have VarDecls; they can have TypedefDecls. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49662 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Treat calls to unresolved functions in the CF-ref count checker as callsTed Kremenek
to functions with NULL summaries. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49660 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-14Updated test cases so that they do not emit warnings for dead stores.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49659 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
2008-04-14Added version of "getClient()" for class Diagnostic that returns a non-constTed Kremenek
reference to the DiagnosticClient. This is useful for DiagnosticClients that have internal state when processing diagnostics. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@49656 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
