Alp Toker d576e00b44 DiagnosticsEngine: update severity setters to new terminology
llvm-svn: 210764
2014-06-12 11:13:52 +00:00
Alp Toker 46df1c0db8 Complete the switch from mappings to declarative diagnostic severities
This begins to address cognitive dissonance caused by treating the Note
diagnostic level as a severity in the diagnostic engine.

No change in functionality.

Alp Toker 57cccec446 ARCMT/GC-check-warn-nsalloc.m: don't provide a diag group
This diagnostic is now controlled solely by -no-ns-alloc-error thus matching
the original intended behaviour.

Alp Toker 403a4f9b82 Get ARCMT/GC-check-warn-nsalloc.m working
The -no-ns-alloc-error migration option now causes the diagnostic to be ignored
completely. If this isn't desired, the error can be downgraded to a warning
using the usual -Wno-error=arcmt-ns-alloc.

Note that we can't use -verify right now on this test because
VerifyDiagnosticConsumer gets confused by multiple SourceManager instances,
which is presumably the reason it was XFAILed in the first place and why the
regression wasn't detected. We'll grep instead for now.

Alp Toker 42aa21222d ARCMigrate: Introduce proper diagnostics for TransformActions
This starts to switch ARCMT to use proper diagnostic messages. The old use was
based on incorrect example code from the documentation.

The logic of the previous report() functions has been retained to support any
external consumers that might be intercepting diagnostic messages through the
old interface.

Note that the change in test/Misc/warning-flags.c isn't a new warning without a
flag, rather one that was previously invisible to the test. Adding a flag might
be a good idea though.

Argyrios Kyrtzidis 712e18a0c1 [objcmt] When emitting a remap file, use a json format with the edit entries, instead of applying the changes
to a temp file directly.

This allows to combine the edits when they can be different based on whether you saw
the implementation or not, e.g. with the designated initializer migration.

Chandler Carruth 3a02247dc9 Sort all of Clang's files under 'lib', and fix up the broken headers
uncovered.

This required manually correcting all of the incorrect main-module
headers I could find, and running the new llvm/utils/sort_includes.py
script over the files.

I also manually added quite a few missing headers that were uncovered by
shuffling the order or moving headers up to be main-module-headers.

Jordan Rose b00073db80 Update VerifyDiagnosticConsumer to only get directives during parsing.
The old behavior was to re-scan any files (like modules) where we may have
directives but won't actually be parsing during the -verify invocation.
Now, we keep the old behavior in Debug builds as a sanity check (though
modules are a known entity), and expect all legitimate directives to come
from comments seen by the preprocessor.

This also affects the ARC migration tool, which captures diagnostics in
order to filter some out. This change adds an explicit cleanup to
CaptureDiagnosticsConsumer in order to let its sub-consumer handle the
real end of diagnostics.

This was originally split into four patches, but the tests do not run
cleanly without all four, so I've combined them into one commit.

Patches by Andy Gibbs, with slight modifications from me.

Ted Kremenek f7639e1b4a Add new code migrator support for migrating existing Objective-C code to use
the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.

This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator.  We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.

Ted Kremenek 8cf47df72f Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted object. I discovered that llvm::RefCountedBase<T> has
a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation
objects created by ASTUnit were actually leaked.  When I fixed that bug locally, it showed that a whole bunch of code assumed
that the LangOptions object that was part of CompilerInvocation was still alive.  By making it heap-allocated and reference counted,
we can keep it around after the CompilerInvocation object goes away.

As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this
object may outlive the CompilerInvocation object.

This commit doesn't fix the CompilerInvocation leak itself.  That will come when I commit the fix to llvm::RefCountedBase<T> to
mainline LLVM.
