AFAIK, there are no -W options for gcc-as and gcc-ld.
It caused failure to build clang with gcc-4.7 on cygwin.

FIXME: Could we recategorize Options for gcc-as and gcc-ld?

This accidentally introduced by r186077, as function names were not
correctly recognized in templated declarations.

Before:
  template <class TemplateIt>
  SomeReturnType
  SomeFunction(TemplateIt begin, TemplateIt end, TemplateIt* stop) {}

After:
  template <class TemplateIt>
  SomeReturnType SomeFunction(TemplateIt begin, TemplateIt end,
                              TemplateIt* stop) {}

This is so aggregates can be passed as var args too.

Summary:
This change turns SanitizerArgs into high-level options
stored in the Driver, which are parsed lazily. This fixes an issue of multiple copies of the same diagnostic message produced by sanitizer arguments parser.

Move C++-specific tests that were checking if we attach a base class comment to
a derived class to an existing test comment-to-html-xml-conversion.cpp.  Note
that the original testing approach was not actually testing the class--comment
relationship.  It only checked that we attached the comment *somewhere*.

The rest of subclass-comment.mm should be also moved elsewhere.

llvm-svn: 188658

comment-misc-tags.m is mostly about miscellaneous Doxygen tags.  Move out tests
that check if the comment is attached to an ObjC decl.  Because the exitsting
test for this is in C++ (annotate-comments.cpp), create a new test --
annotate-comments-objc.m.

The rest of comment-misc-tags.m should be also moved elsewhere.

Revert "Revert "DebugInfo: Omit debug info for dynamic classes in TUs that do not have the vtable for that class""

This reverts commit r188600.

r188640/r188639 fixed the root cause of the crash-on-valid that r188600
originally introduced. This now appears to bootstrap debug clang
successfully to the best of my testing.

llvm-svn: 188642

Remove throw() from Stmt::operator new so the compiler will omit the null check on the result since ASTContext allocator won't return null.

llvm-svn: 188641

A partner to r188639, this is a somewhat heavy-handed fix to the general
issue, since even after that prior change the issue does still
unavoidably arise with template parameters (see test case).

There are other ways we could consider addressing this (see FIXME).

llvm-svn: 188640

Possible minor reduction in debug info & avoid some cases where creating
a context chain could lead to the type the context chain is being
created for, being created. (this is still possible with template
parameters - tests/fixes/improvements to follow)

llvm-svn: 188639

llvm-svn: 188638

Make expression allocation methods use a 'const' reference to the ASTContext since the underlying operator new only needs a const reference.

llvm-svn: 188636

llvm-svn: 188625

loop processing the candidates can cause new declerations to be added to
the context, invalidating lookup_result. To avoid that, make a copy of
the list of declarations to iterate over.

I don't have a way to check in a test case for this as it involves
a giant pile of source code and a generated PCH file used to accelerate
code completion, all of this running under ASan.

Fixes a crash-on-valid introduced by r188486 (which should've occurred
earlier but for a blatant bug where calling createFwdDecl from the
requireCompleteType callback was useless under -flimit-debug-info and we
were just getting lucky with other later callbacks requiring the type
anyway).

Per feedback from Chandler, it's better to have libraries with more specific functionality.
LibIndex will contain the indexing functionality of libclang, which includes USR generation.
