Zhongxing Xu b7cf95957d Instead of setting the default value of the array region, bind the rest of the 
array elements to 0 explicitly. Create 0 values with the element type.

Chris Lattner c183595534 Fix our check for "random whitespace between a \ and newline" to work 
with dos style newlines.  I have a trivial test for this:

// RUN: clang-cc %s -verify
#define test(x, y) \
   x ## y

but I don't know how to get svn to not change newlines and testrunner
doesn't work with dos style newlines either, so "not worth it". :)

Chris Lattner e2170edfbb switch Warnings.cpp to use the diagnostics machinery to print diagnostics, not *fprintf*! 
Among other things, this makes the warning about unknown warning options mappable.
For example:

$ clang t.c -Werror -Wfoo
error: unknown warning option '-Wfoo' [-Wunknown-warning-option]

For another thing, they are properly color coded now too :)

Ted Kremenek fb87e30815 MemRegions: 
- Embed a reference to MemRegionManager objects in MemSpaceRegion objects
- Use this embedded reference for MemRegion objects to access ASTContext objects without external help
- Use this access to ASTContext to simplify 'isBoundable' (no ASTContext& argument required)

 2009-06-22 23:20:33 +00:00
Ted Kremenek e5e8b0b09b Refactor some of the logic in MemRegionManager for constructing regions using 
member template functions and traits. The idea is to allow MemRegionManager to
construct subclasses of MemRegion that aren't declared in MemRegion.h (e.g.,
checker-specific regions).

Douglas Gregor 0b6a6242ed Rework the way we track which declarations are "used" during 
compilation, and (hopefully) introduce RAII objects for changing the
"potentially evaluated" state at all of the necessary places within
Sema and Parser. Other changes:

  - Set the unevaluated/potentially-evaluated context appropriately
    during template instantiation.
  - We now recognize three different states while parsing or
    instantiating expressions: unevaluated, potentially evaluated, and
    potentially potentially evaluated (for C++'s typeid).
  - When we're in a potentially potentially-evaluated context, queue
    up MarkDeclarationReferenced calls in a stack. For C++ typeid
    expressions that are potentially evaluated, we will play back
    these MarkDeclarationReferenced calls when we exit the
    corresponding potentially potentially-evaluated context.
  - Non-type template arguments are now parsed as constant
    expressions, so they are not potentially-evaluated.

Argyrios Kyrtzidis a3aeb5a8f1 Introduce Decl::getSourceRange() which, like Stmt::getSourceRange(), represents the range that the declaration covers. 
Add initial support for NamespaceDecl, VarDecl, and FunctionDecl:
-NamespaceDecl range is from name to '}'
-VarDecl is from name to possible init expression
-FunctionDecl is from name to last parameter name or to end of its function body.

Douglas Gregor c9c02ed8f4 Keep track of when declarations are "used" according to C and 
C++. This logic is required to trigger implicit instantiation of
function templates and member functions of class templates, which will
be implemented separately.

This commit includes support for -Wunused-parameter, printing warnings
for named parameters that are not used within a function/Objective-C
method/block. Fixes <rdar://problem/6505209>.

Ted Kremenek c55f0cdaa0 Remove more GetSVal/GetLValue methods in GRExprEngine/GRState, instead 
preferring to use their replacements in GRState. This further unifies the code
paths for such logic and leads to some code reduction.

Zhongxing Xu 54fb536b5c A further step of r73690: associate the cast-to type with the created symbol, 
because the type of the symbol is used to create the default range. We need the
sign to be consistent.
