when deserialized, fixing random crashes in libclang.
Also simplifies how OpaqueValueExprs are [de]serialized.
The reader/writer automatically retains pointer equality of sub-statements (when a
statement node is referenced in multiple nodes), so no need to manually handle it.

"main" files that import modules. When loading any of these kinds of
AST files, we make the modules that were imported visible into the
translation unit that loaded the PCH file or preamble.

For example, the warning for printf("%zu", 42.0);
changes from "conversion specifies type 'unsigned long'" to "conversion
specifies type 'size_t' (aka 'unsigned long')"
llvm-svn: 145697
only the macro definitions from visible (sub)modules will actually be
visible. This provides the same behavior for macros that r145640
provided for declarations.

within module maps, which will (eventually) be used to re-export a
module from another module. There are still some pieces missing,
however.
llvm-svn: 145665
(sub)module, all of the names may be hidden, just the macro names may
be exposed (for example, after the preprocessor has seen the import of
the module but the parser has not), or all of the names may be
exposed. Importing a module makes its names, and the names in any of
its non-explicit submodules, visible to name lookup (transitively).
This commit only introduces the notion of name visible and marks
modules and submodules as visible when they are imported. The actual
name-hiding logic in the AST reader will follow (along with test cases).

We are getting name of the called function or it's declaration in a few checkers. Refactor them to use the helper function in the CheckerContext.
llvm-svn: 145576
force the unknown any type to "id" so that the message send can be
completed without requiring a case. Fixes <rdar://problem/10506646>.
llvm-svn: 145552
a standard global/local scheme, so that submodule definitions will
eventually be able to refer to submodules in other top-level
modules. We'll need this functionality soonish.
llvm-svn: 145549
explicit template specializations (which represent actual functions somebody wrote).
Along the way, refactor some other code which similarly cares about whether or
not they are looking at a template instantiation.
llvm-svn: 145547
declaration tickles a bug in the way we handle visibility pragmas.
The improvement to error recovery for template function definitions declared
with the 'typedef' specifier in r145372 is unrelated and not reverted here.
llvm-svn: 145541
library, since modules cut across all of the libraries. Rename
serialization::Module to serialization::ModuleFile to side-step the
annoying naming conflict. Prune a bunch of ModuleMap.h includes that
are no longer needed (most files only needed the Module type).
llvm-svn: 145538
we may end up having added more pending stuff to do, so go in a loop until everything
is cleared out.
This fixes the error in rdar://10278815 which has a certain David Lynch-esque quality..
error: unknown type name 'BOOL'; did you mean 'BOOL'?
llvm-svn: 145536
submodules. This information will eventually be used for name hiding
when dealing with submodules. For now, we only use it to ensure that
the module "key" returned when loading a module will always be a
module (rather than occasionally being a FileEntry).
llvm-svn: 145497
really bad way to go about this, but I'm not sure there's a better
choice without substantial changes to TreeTransform --- most
notably, preserving implicit semantic nodes instead of discarding
and rebuilding them.
llvm-svn: 145480
check whether the named submodules themselves are actually
valid, and drill down to the named submodule (although we don't do
anything with it yet). Perform typo correction on the submodule names
when possible.
llvm-svn: 145477
The new metadata are method @encode strings with additional data.
1. Each Objective-C object is marked with its class name and protocol names.
The same is done for property @encode already.
2. Each block object is marked with its function prototype's @encoding. For
example, a method parameter that is a block object that itself returns void
and takes an int would look like:
@?<v@?i>
These new method @encode strings are stored in a single array pointed to by structs protocol_t and objc_protocol_ext.

declaration at namespace scope is followed by a semicolon and an open-brace
(or in C++, a 'try', ':' or '='), then the error is probably a function
definition with a spurious ';', rather than a mysterious '{'.
llvm-svn: 145372
return the module itself (in the module map) rather than returning the
umbrella header used to build the module. While doing this, make sure
that we're inferring modules for frameworks to build that module.
llvm-svn: 145310
Specify that these files should be installed to the optional internal
install location as specified by configure's --with-internal-prefix.
If that option is not used, they'll be installed to the default prefix
as before.
