Devang Patel 9fc4341eec It is possible that main input file does not have any symbol with debug info. To handle this edge case, always create main compile unit first.
This fixes PR 4228.

Chris Lattner 651a221cc2 follow-on to my patch: some targets (like sparc) do not
have target-specific builtins, and do not set the count.
Just default to 0 for these targets.

Chris Lattner 4ef49c1d6e my refactoring of builtins changed target-specific builtins to only be
registered when PCH wasn't being used.  We should always install (in BuiltinInfo)
information about target-specific builtins, but we shouldn't register any builtin
identifier infos.  This fixes the build of apps that use PCH and target specific
builtins together.

Chris Lattner 6ed7d5964e Minor tweak to -fdiagnostics-print-source-range-info to make it print
ranges more similar to the console output.  Consider:

#define FOO(X, Y) X/ Y

void foo(int *P, int *Q) {
  FOO(P, Q);
}

Before we emitted:

t.c:4:3:{4:3-4:6}{4:3-4:6}: error: invalid operands to binary expression ('int *' and 'int *')
   FOO(P, Q);
   ^~~~~~~~~
...

Note that while we underline the macro args that the range info just includes FOO 
without its macros.  This change teaches the printed ranges to include macro args
also so that we get:

t.c:4:3:{4:3-4:12}{4:3-4:12}: error: invalid operands to binary expression ('int *' and 'int *')
   FOO(P, Q);
   ^~~~~~~~~
...

Chris Lattner c7d2bfacef "GCC emits an __objc_class_name_{classname} symbol for every class, and a corresponding reference to this symbol for every compilation unit that references the class. This causes linker errors when you try linking a program which references some classes but doesn't define them. The attached patch implements this support in clang, so you can compile a class with clang, reference it in a file compiled with GCC, and have it all work correctly."

Douglas Gregor e141633f55 Introduce a SFINAE "trap" that keeps track of the number of errors
that were suppressed due to SFINAE. By checking whether any errors
occur at the end of template argument deduction, we avoid the
possibility of suppressing an error (due to SFINAE) and then
recovering so well that template argument deduction never detects that
there was a problem. Thanks to Eli for the push in this direction.

Douglas Gregor 33834516f3 Update LLVM.
Implement support for C++ Substitution Failure Is Not An Error
(SFINAE), which says that errors that occur during template argument
deduction do *not* produce diagnostics and do not necessarily make a
program ill-formed. Instead, template argument deduction silently
fails. This is currently implemented for template argument deduction
during matching of class template partial specializations, although
the mechanism will also apply to template argument deduction for
function templates. The scheme is simple:

  - If we are in a template argument deduction context, any diagnostic
    that is considered a SFINAE error (or warning) will be
    suppressed. The error will be propagated up the call stack via the
    normal means.
  - By default, all warnings and errors are SFINAE errors. Add the
    NoSFINAE class to a diagnostic in the .td file to make it a hard
    error (e.g., for access-control violations).

Note that, to make this fully work, every place in Sema that emits an
error *and then immediately recovers* will need to check
Sema::isSFINAEContext() to determine whether it must immediately
return an error rather than recovering.

Chris Lattner 8e3eed0890 change ParseStatementOrDeclaration to emit the 'missing ;' with
ExpectAndConsume instead of custom diag logic.  This gets us an
insertion hint and positions the ; at the end of the line 
instead of on the next token.  Before:

t.c:5:1: error: expected ';' after return statement
}
^

after:

t.c:4:11: error: expected ';' after return statement
  return 4
          ^

Chris Lattner b6f77af532 implement and document a new __has_feature and __has_builtin magic
builtin preprocessor macro.  This appears to work with two caveats:
1) builtins are registered in -E mode, and 2) target-specific builtins
are unconditionally registered even if they aren't supported by the
target (e.g. SSE4 builtin when only SSE1 is enabled).
