Summary:
Hexagon is being updated, but there is not enough to pass these tests.

some bugs in the ASTImporter that this exposed:
- When importing functions, the body (if any) was
previously ignored. This patch ensures that the
body is imported also.
- When a function-local Decl is imported, the first
thing the ASTImporter does is import its context
(via ImportDeclParts()). This can trigger
importing the Decl again as part of the body of
the function (but only once, since the function's
Decl has been added to ImportedDecls). This patch
fixes that problem by extending ImportDeclParts()
to return the imported Decl if it was imported as
part of importing its context, and the patch adds
ASTImporter::GetAlreadyImportedOrNull() to support
this query. All callers of ImportDeclParts return
the imported version of the Decl if ImportDeclParts()
returns it.
- When creating functions, InnerLocStart of the source
function was re-used without importing. This is a
straight up bug, and this patch makes ASTImporter
import the InnerLocStart and use the imported version.
- When importing FileIDs, the ASTImporter previously
always tried to re-load the file for the corresponding
CacheEntry from disk. This doesn't work if the
CacheEntry corresponds to a named memory buffer. This
patch changes the code so that if the UniqueID for the
cache entry is invalid (i.e., it is not a disk file)
the whole entry is treated as if it were invalid, which
forces an in-memory copy of the buffer.
Also added test cases, using the new support committed in
236011.

By adding a default config.excludes pattern we can avoid individual
suppressions in subdirectories.
This matches LLVM's lit.cfg which also excludes a few other common non-test
filenames for consistency.

VerifyDiagnosticConsumer previously would not check that the diagnostic and
its matching directive referenced the same source file. Common practice was
to create directives that referenced other files but only by line number,
and this led to problems such as when the file containing the directive
didn't have enough lines to match the location of the diagnostic in the
other file, leading to bizarre file formatting and other oddities.
This patch causes VerifyDiagnosticConsumer to match source files as well as
line numbers. Therefore, a new syntax is made available for directives, for
example:
// expected-error@file:line {{diagnostic message}}
This extends the @line feature where "file" is the file where the diagnostic
is generated. The @line syntax is still available and uses the current file
for the diagnostic. "file" can be specified either as a relative or absolute
path - although the latter has less usefulness, I think! The #include search
paths will be used to locate the file and if it is not found an error will be
generated.
The new check is not optional: if the directive is in a different file to the
diagnostic, the file must be specified. Therefore, a number of test-cases
have been updated with regard to this.
This closes out PR15613.
llvm-svn: 179677
produce a note for that diagnostic either with a different DiagnosticEngine or
after calling DiagnosticEngine::Reset(). That didn't make any sense, and did the
wrong thing if the original diagnostic was suppressed.
llvm-svn: 170636
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.

-Add the location of the class name to all objc container decls, not just ObjCInterfaceDecl.
-Make objc decls consistent with the rest of the NamedDecls and have getLocation() point to the
class name, not the location of '@'.

required modifying a few tests that specifically use note include stacks
to check the source manager's view of include stacks. I've simply added
the flag to these tests for now, they may have to be more substantially
changed if we decide to remove support for note include stacks
altogether.
Also, add a test for include stacks on notes that was supposed to go in
with the previous commit.

of errors and warnings. This allows us to emit something like this:
2 warnings and 1 error generated.
instead of:
3 diagnostics generated.
This also stops counting 'notes' because they are just follow-on information
about the previous diag, not a diagnostic in themselves.

comparing their types under the assumption that they are equivalent,
rather than importing the types and then checking for compatibility. A
few minor tweaks here:
- Teach structural matching to handle compatibility between
function types with prototypes and those without prototypes.
- Teach structural matching that an incomplete record decl is the
same as any other record decl with the same name.
- Keep track of pairs of declarations that we have already checked
(but failed to find as structurally matching), so we don't emit
diagnostics repeatedly.
- When importing a typedef of an anonymous tag, be sure to link the
imported tag type to its typedef.
With these changes, we survive a repeated import of <stdlib.h> and
<stdio.h>. Alas, the ASTNodeImporter is getting a little grotty.

two types in different AST contexts are equivalent. Rather than
transforming the type from one context into the other context, we
perform a deep structural comparison of the types. This change
addresses a serious problem with recursive data types like
struct ListNode {
int value;
struct ListNode *Next;
} xList;
llvm-svn: 96278
incompatibility and show where the structural differences are. For
example:
struct1.c:36:8: warning: type 'struct S7' has incompatible definitions
in different translation units
struct S7 { int i : 8; unsigned j : 8; } x7;
^
struct1.c:36:33: note: bit-field 'j' with type 'unsigned int' and length 8 here
struct S7 { int i : 8; unsigned j : 8; } x7;
^
struct2.c:33:33: note: bit-field 'j' with type 'unsigned int' and length 16 here
struct S7 { int i : 8; unsigned j : 16; } x7;
^
There are a few changes to make this work:
- ASTImporter now has only a single Diagnostic object, not multiple
diagnostic objects. Otherwise, having a warning/error printed via
one Diagnostic and its note printed on the other Diagnostic could
cause the note to be suppressed.
- Implemented import functionality for IntegerLiteral (along with
general support for statements and expressions)
