Finish up method prototype parsing.

Next step...starting installing class names into the type namespace (so we can start parsing Cocoa headers).

In CFG dumper, refactored the code to print block terminators into a
StmtVisitor.

Added the method "FinishBlock" to CFGBuilder to do the reversal of statements
in a block instead of calling "reverseStmts" for a block directly.  This
was necessary to fix a bug in how blocks with labels were being processed
(some cases would cause the statements to be reversed twice).  FinishBlock
detects blocks that start with labels and doesn't do a second reversal.

Starting value of second loop's induction variable can not be lower 
then starting value of original loop's induction variable.

Add support for parsing method prototypes (and other stuff required by @interface).

Still need to finish Parser::ParseObjCMethodDecl(). Before I do, I need to do a minor
refactoring of ParseDeclarationOrFunctionDefinition(), to disallow function definitions.
At the moment, @inteface allows function defs (which is incorrect).

the selection statements and iteration statements.  Add
spec citations.

This fixes test/Parser/control-scope.c

llvm-svn: 41263

Modified CFG so that getEntry(), getExit(), front() and back() return
CFGBlock& instead of CFGBlock*.

Dror GCCLibraries: they are obsolete since 2.0 release. This also reduces number of licenses used in LLVM.

dispatch to walk the AST.

llvm-svn: 41253

Added builder code to translate ASTs to CFGs.  This currently supports
if, return, and non-control flow statements.

Added pretty-printer to debug CFGs.

Added a "-dump-cfg" option to the clang driver to dump CFGs for code
sent through the frontend.

void foo() {
  int x
  if (x) {
  }
}

We now emit:

a.c:5:3: error: parse error
  if (x) {
  ^
1 diagnostic generated.

instead of:

a.c:5:3: error: parse error
  if (x) {
  ^
a.c:9:1: error: expected '}'

^
2 diagnostics generated.
