Ted Kremenek 7f770032c7 Don't run -Wunreachable-code on template instantiations. Different instantiations may produce different unreachable code results, and it is very difficult for us to prove that ALL instantiations of a template have specific unreachable code. If we come up with a better solution, then we can revisit this, but this approach will at least greatly reduce the noise of this warning for code that makes use of templates.

Bob Wilson a0c69014f8 Remove the install-clang-c makefile target. 
When I did this before it broke a buildbot that was testing that target, but
we've removed that buildbot now.

it to GNU assembler. In addition, change function getMipsArchFromCPU() so that
it can be reused in ConstructJob().

Douglas Gregor 11729f01f9 Move the module auto-import logic after the logic that allows a 
callback client to suggest an alternative search path and after we
complain when the included file can't be found. The former can't be
tested in isolation, the latter doesn't actually matter (because we
won't make a module suggestion if no header is available). However,
the flow is better this way.

Douglas Gregor 6902197407 Implement (de-)serialization of the description of a module and its 
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).

John McCall e929082806 Fix the instantiation of pseudo-object expressions. This is a 
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.

Douglas Gregor 1805b8a42f Teach the preprocessor how to handle module import declarations that 
involve submodules (e.g., importing std.vector), rather than always
importing the top-level module.

llvm-svn: 145478
 2011-11-30 04:26:53 +00:00
Douglas Gregor 5196bc6b39 When loading a module that involves submodules (e.g., std.vector), 
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.

Bob Wilson 5f4e3a780f Add bigger method type encodings to protocol objects. <rdar://problem/10492418> 
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.

Patch provided by Greg Parker!

Johnny Chen 99bb50c10d rdar://problem/9211445 
Fix wrong test logic in test_modules_search_paths().  Add additional exercising of 'target modules search-paths list/query".
There is a reproducible crash if 'target modules search-paths clear' is exercised during test teardown.
So we currently comment out the stmt as follows:

        # Add teardown hook to clear image-search-paths after the test.
        # rdar://problem/10501020
        # Uncomment the following to reproduce 10501020.
        #self.addTearDownHook(lambda: self.runCmd("target modules search-paths clear"))
