New Revision: 249747
URL: http://llvm.org/viewvc/llvm-project?rev=249747&view=rev
Log:
Moved the target specific ClangASTContext initialization over into
ClangASTContext::CreateInstance.
This involved changing the TypeSystem::CreateInstance to take a module or a
target. This allows type systems to create an AST for modules (no expression
support needed) or targets (expression support is needed) and return the
correct class instance for both cases.
