Fix bug in terminator processing for uninitialized-values: simply ignore the 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.

Fixed regressions in error reporting due to copy-paste errors (using the "begin"
iterator instead of "end") and not implementing "getDescription()" for Nil

16 years agorefactor Parser::ParseStructDeclaration to return a vector of uninterpreted
Chris Lattner [Thu, 10 Apr 2008 06:46:29 +0000 (06:46 +0000)]
refactor Parser::ParseStructDeclaration to return a vector of uninterpreted
declarators.  This allows the clients (C structs, objc classes, objc
properties, [future] C++ classes) etc, to do custom processing before invoking
an action.

This has two benefits in the short term:
1) objc ivar processing should be split out of ActOnField into its own ActOn method.
2) the new objc ivar action can take visibility info directly, eliminating
   AllVisibilities in ParseObjCClassInstanceVariables.
3) objc properties can pass their own special sauce down to sema as well.

Major refactoring/cleanup of GRExprEngine, ExplodedGraph, and BugReporter.

Bugs are now reported using a combination of "BugType" (previously
BugDescription) and Bug "BugReport" objects, which are fed to BugReporter (which
generates PathDiagnostics). This provides a far more modular way of registering
bug types and plugging in diagnostics.

GRExprEngine now owns its copy of GRCoreEngine, and is not owned by the
ExplodedGraph.

ExplodedGraph is no longer templated on the "checker", but instead on the state
contained in the nodes.
