2011-11-15Fix a regression from 143657. The second pass of the warning options should ↵Chad Rosier
only be emitting warnings/errors for unknown warning options. getDiagnosticsInGroup returns false if the diagnostics is found and true otherwise. Thus, if we're reporting and we have a valid diagnostic, we were actually setting the flag and causing mayhem. rdar://10444207 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144670 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-14Don't track depfiles as result files which need to be cleaned up on failure.Matt Beaumont-Gay
This is a partial revert of r143846. While cleaning up after a crash is probably a good idea, we were also deleting .d files if the compilation failed due to invalid input, which is not the desired behavior. The test is XFAIL'd until the cleanup code can be reworked to do the right thing. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144590 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-14Use Sema::RequireCompleteType to check for the completeness ofDouglas Gregor
Objective-C classes. This has two purposes: to consistently provide "forward declaration here" notes when we hit an incomplete type, and to give LLDB a chance to complete the type.

2011-11-12[PCH] When completing an objc forward reference, do not serialize the chain ↵Argyrios Kyrtzidis
of its categories because it is going to be rewritten (and the chain will be serialized again), otherwise we may form a cycle in its categories list when deserializing. Also introduce ASTMutationListener::CompletedObjCForwardRef to notify that a forward reference was completed; using Decl's isChangedSinceDeserialization/setChangedSinceDeserialization is bug inducing and kinda gross, we should phase it out.

2011-11-12Implement a minor optimization when loading module maps to satisfy aDouglas Gregor
module import: don't re-check for a loaded module unless we've actually loaded a new module map file. Already-loaded module map files aren't interesting. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144435 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-11Teach the search for modules to consider modules described by a moduleDouglas Gregor
map, so long as they have an umbrella header. This makes it possible to introduce a module map + umbrella header for a given set of headers, to turn it into a module. There are two major deficiencies here: first, we don't go hunting for module map files when we just see a module import (so we won't know about the modules described therein). Second, we don't yet have a way to build modules that don't have umbrella headers, or have incomplete umbrella headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144424 91177308-0d34-0410-b5e6-96231b3b80d8
2011-11-11Wire up the mapping from header files mentioned in module maps over toDouglas Gregor

2011-11-11Introduce basic support for parsing module map files.Douglas Gregor
Module map files provide a way to map between headers and modules, so that we can layer a module system on top of existing headers without changing those headers at all. This commit introduces the module map file parser and the module map that it generates, and wires up the module map file parser so that we'll automatically find module map files as part of header search. Note that we don't yet use the information stored in the module map. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144402 91177308-0d34-0410-b5e6-96231b3b80d8

reinstates r144273; a combination of r144333's fix for NoOp rvalue-to-lvalue casts and some corresponding changes here resolve the regression which that caused.
