2008-02-13Renamed files to match class renaming in r47070:Ted Kremenek
http://llvm.org/viewvc/llvm-project?rev=47070&view=rev git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47071 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-13Renamed class GREngine => GRCoreEngine.Ted Kremenek
Renamed class GRConstants => GRExprEngine. This was done with a Perl script, and will result in 80 col. violations that I will gradually fix up. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47070 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-13Simplify GRIndirectGotoNodeBuilder.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47068 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-13Added GREngine support for "break" and "continue".Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47064 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-13Added support to GREngine/GRConstants for handling computed gotos.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47038 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-12Added GREngine support for GotoStmt.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47034 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-12Added GRBlockCounter class, which tracks the number of times blocksTed Kremenek
have been visited in a path. Added GRBlockCounter as an item to be enqueued to the worklist. Modified "ProcessBranch" in GRConstants to prune branches with symbolic conditions that have been already taken. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@47010 91177308-0d34-0410-b5e6-96231b3b80d8
2008-02-05Implemented initial transfer function support for '&&', '||', '?', andTed Kremenek
__builtin_choose. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46731 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-30We now delay adding nodes created by GRBranchNodeBuilder to the analysisTed Kremenek
worklist until the dstor of GRBranchNodeBuilderImpl. This way clients can mark creates nodes as "sinks" before they are added to the worklist. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46582 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-30Implemented some branch pruning in GRConstants using != and == forTed Kremenek
constant integers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46581 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-29Implemented more boilerplate in GREngine for processing branches. NowTed Kremenek
we automatically generate a new successor node along an edge if the checker did not explicitly do so (i.e., we just propagate the current state). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46536 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-29Added boilerplate logic in GREngine for processing branches.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46532 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-29Renamed GRNodeBuilder to GRStmtNodeBuilder.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46531 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-29Driver now passes the top-level FunctionDecl* to GRConstants.Ted Kremenek
Refactoring: for GREngine and GRConstants, pushed references to CFG, ASTContext, and the top-level FunctionDecl into ExplodedGraphImpl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46475 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16Fixed iterator bug in ExplodedNodeImpl::NodeGroup::end(); we would improperlyTed Kremenek
handle the case where the number of nodes was 0. Fixed bug in GREngineImpl where we did not proceed to the next statement when processing a PostStmt location. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46093 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-16Hooked up the GRConstants analysis to the driver.Ted Kremenek
Fixed some compilation errors with GREngine that showed up during template instantiation. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@46074 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-15Removed implicit transitions to a "BlockExit" location; we now handleTed Kremenek
the end of the block by processing empty blocks (at BlockEntrance) or when we have just processed the last statement in a block (at PostStmt). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45991 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-14Added prototype implementation of path-sens. analysis core engine.Ted Kremenek
git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@45986 91177308-0d34-0410-b5e6-96231b3b80d8
