Marcin Swiderski 772324971d - Fixed subexpressions evaluation order for binary operators to match order in code generated with the compiler, 
- Fixed test cases for unreachable code warnings produced by Sema.

Ted Kremenek 12a37de003 Previously, the printf warnings would say your arguments type was 'int' when it was really a 'char' 
or a 'short'. This fixes that and allows the hints to suggest 'h' modifiers for small ints.

Patch by Justin Bogner!

 2010-10-01 03:00:16 +00:00
Zhongxing Xu ea360a3b1a The old logic would add non-struct and non C++ struct variables to the local 
scope. Now we only add C++ struct with non-trivial destructor variables to the
local scope.

Marcin Swiderski 8b99b8a782 In preparation for adding generation of destructors for objects with automatic storage added: 
- LocalScope class with iterator used to pointing into it,
- fat doxygen comment for LocalScope indended usage,

Ted Kremenek 35965b972e Remove from the CFG the half-implemented support for scoping information. We decided that scope information doesn't belong in the CFG at all, since it is a lexical construct.

Ted Kremenek f2b0a1bfa0 Enhance -Wunreachable-code to not consider the 'default:' branch of a switch statement live if a switch on an enum value has 
explicit 'case:' statements for each enum value.

llvm-svn: 113451
 2010-09-09 00:06:10 +00:00
Ted Kremenek b037185b52 Add 'filtered_pred_iterator' and 'filtered_succ_iterator' to CFGBlock. This allows a client 
to selectively walk successors/predecessors based on commonly used filters.  For starters, add
a filter to ignore 'default:' cases for SwitchStmts when all enum values are covered by CaseStmts.

Ted Kremenek 82bfc86792 Explicitly handle CXXExprWithTemporaries during CFG construction by just visiting the subexpression. While we don't do anything intelligent right now, this obviates a bogus -Wunreahable-code warning reported in PR 6130.

 2010-08-28 00:19:02 +00:00
Tom Care e5aa30c722 Add alternate version of LiveVariables analysis that does not kill liveness at assignments. This 'relaxed' liveness is useful in path sensitive analysis for situations where the resulting extended liveness allows us to find some bugs. 
- Added killAtAssign flag to LiveVariables
- Added relaxed LiveVariables to AnalysisContext with an accessor
