2008-10-15Enhance dead store checker to not flag preincrements to dead variables where ↵Ted Kremenek
the preincrement is a subexpression, e.g. foo(++x); This can cause false negatives, but will remove a whole class of false positives. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@57554 91177308-0d34-0410-b5e6-96231b3b80d8
2008-09-20Add "category" to BugTypes, allowing bugs to be grouped.Ted Kremenek
Changed casing of many bug names. The convention will be to have bug names (mostly) lower cased, and categories use some capitalization. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@56385 91177308-0d34-0410-b5e6-96231b3b80d8

2008-08-09Don't use Expr::isIntegerConstantExpr just to check if a pointer value is ↵Ted Kremenek
initialize to NULL. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54563 91177308-0d34-0410-b5e6-96231b3b80d8
2008-08-07Don't flag any dead stores for variables marked unused.Ted Kremenek

2008-08-05Added decl_iterator to DeclStmt to provide an abstract interface to iterate ↵Ted Kremenek
over the ScopedDecls of a DeclStmt. Updated a few clients of DeclStmt::getNextDeclarator() to use decl_iterator instead. Will update other clients after additional testing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@54368 91177308-0d34-0410-b5e6-96231b3b80d8

2008-07-23Don't flag dead stores when the result of a preincrement/predecrement is ↵Ted Kremenek
used in an enclosing expression. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53964 91177308-0d34-0410-b5e6-96231b3b80d8
2008-07-23Further refine dead store checking to distinguish between dead stores and ↵Ted Kremenek
dead increments. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@53960 91177308-0d34-0410-b5e6-96231b3b80d8
