verify that the source range corresponds to the current file, not
just the current line.  This allows us to emit:

a.c:1:44: error: invalid operands to binary expression ('double' and 'int *')
double a; int *b; void f(void) { int c = a +
                                         ~ ^

instead of:

a.c:1:44: error: invalid operands to binary expression ('double' and 'int *')
double a; int *b; void f(void) { int c = a +
~                                        ~ ^

for PR1906 (note the leading ~).

Thanks to Neil for noticing this.

Do not use std::cerr; use llvm::cerr instead.

to have a much simpler, cleaner interpretation of what is a "location"
in a function (as encoded by a CFG).

- Teach Expr::isConstantExpr() about InitListExpr's (and offsetof, since I noticed it was missing).
- Rename CheckInitializer() to CheckInitializerTypes().
- Removed the isStatic argument to CheckInitializerTypes() and all of it's subroutines. Checking for constant expressions is now done separately.
- Added CheckForConstantInitializer().

Add a FIXME to commit r45784. Thanks mrs!

Fix Sema::ActOnDeclarator() to call MergeFunctionDecl for function decls that aren't in scope. Since C functions are in a flat namespace, we need to give them special treatment (when compared with variables and typedefs).

llvm-svn: 45789

so that nodes can be marked as representing an infeasible program point. This
flag lets the path-sensitive solver know that no successors should be generated
for such nodes.

BExpr*** and ***BExpr respectively. These edges represent program locations
between the entrance/exit of a block and Block-level Expressions.

Also added ***SExpr and SExpr*** ProgramEdges to represent the locations in the
program between the evaluation of subexpressions and block-level expressions.

code restructuring.  (new files will be introduced shortly)

llvm-svn: 45785

Fix ASTContext::typesAreCompatible to allow for int/enum compatibility (C99 6.7.2.2p4).
Fix Sema::MergeFunctionDecl to allow for function type compatibility (by using the predicate on ASTContext). Function types don't have to be identical to be compatible...

llvm-svn: 45784

Teach Sema::ActOnCompoundLiteral about constraint C99 6.5.2.5p3.

truncating.  This allows us to compile:
 void foo() {
  static _Bool foo = 4;
}

into:
@foo1 = internal global i8 1
instead of:
@foo1 = internal global i8 4
