2011-08-12Cleanup various declarations of 'Stmt*' to be 'Stmt *', etc. in libAnalyzer ↵Ted Kremenek
and libStaticAnalyzer[*]. It was highly inconsistent, and very ugly to look at. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@137537 91177308-0d34-0410-b5e6-96231b3b80d8
2009-12-19Remove ';' after method definition. Noticed by clang++, which one would thinkDaniel Dunbar
would have a higher respect for its own code. This is getting old, is this warning really adding value? git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@91779 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-16Move the source-level CFG from libAST to libAnalysis.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76092 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17Modified the notion of "Block-level expressions" in CFGs to include Stmt*. ThisTed Kremenek
is because GNU-style Statement-expressions cause the last statement in the statement-expression to act like an expression. We now have two notions: block-level statements and block-level expressions. The former are all Stmt* that appear in the list of statements in CFGBlocks. The latter is the subset of the former; these block-level statements are used as subexpressions somewhere in the AST. CFG::isBlockExpr() returns true for the latter, not the former (previously isBlockExpr() always returned true for non-Expr Stmt*). Modified the LiveVariables analysis to also track liveness state for block-level expressions (using the updated definition of block-level expressions). Modified the dataflow solver so that when it records values for block-level statements, it records the dataflow value *before* the transfer function for a Stmt* is evaluated (not after). This is more in sync in what clients will want. Modified CFGStmtVisitor to record the current block-level statement. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46143 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-17Added support to dataflow solver to (when requested) also record dataflowTed Kremenek
values for the block-level expressions. Modified 'LiveVariables' to provide the option to clients to record liveness information for block-level expressions (using the above feature). Modified 'DeadStores' to conform to the new interface of 'LiveVariables'. Modified 'GRConstants' to compute liveness information for block-level expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46137 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-11Renamed ProgramEdge.h to ProgramPoint.hTed Kremenek

2008-01-11Renamed ProgramEdge to ProgramPoint and changed subclasses of ProgramEdgeTed Kremenek
to have a much simpler, cleaner interpretation of what is a "location" in a function (as encoded by a CFG). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45846 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29Don't attribute in file headers anymore. See llvmdev for theChris Lattner
discussion of this change. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45410 91177308-0d34-0410-b5e6-96231b3b80d8
2007-10-02Moved ProgramEdge out out include/.../Analysis/PathSensitive to ↵Ted Kremenek
include/.../Analysis, as it is now used by the FlowSensitive subsystem as well. Removed "Edge" nested class by CFG, as it is now subsumed by ProgramEdge. Adjusted DataflowSolver and DataflowValues to use ProgramEdges instead of CFG::Edge. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42534 91177308-0d34-0410-b5e6-96231b3b80d8
2007-09-25Moved "DataflowSolver.h" to the "include/" subtree. Adjusted clientTed Kremenek
code that uses the solver to reflect the new location. Created "FlowSensitive" subdirectory in include/clang/Analysis to hold header files relating to flow-sensitive analyses. Moved "DataflowValues.h" into this subdirectory. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@42320 91177308-0d34-0410-b5e6-96231b3b80d8
