My testing shows that function stat has no problem with trailing separators. (tested on Windows and Darwin).

This fixes a bug on Windows:
clang c:\test.cpp

Here the call stat("c:") is not recognized as a directory (must be "c:\").

I'll try to implement this functionality again soon.

diagnostic group to cover the cases where we have definitively bad
behavior: dynamic classes.

It also rips out the existing support for POD-based checking. This
didn't work well, and triggered too many false positives. I'm looking
into a possibly more principled way to warn on the fundamental buggy
construct here. POD-ness isn't the critical aspect anyways, so a clean
slate is better. This also removes some silliness from the code until
the new checks arrive.

the template parameter, perform the checking as a "specified" template
argument rather than a "deduced" template argument; the latter implies
stricter type checking that is not permitted for default template
arguments.

Also, cleanup our handling of substitution of explicit template
arguments for a function template. We were actually performing some
substitution of default arguments at this point!

Fixes PR10069.

DeclRefExprs, IntegerLiterals, and others, reducing Cocoa PCH size by
~1% and C++ header size by ~2.5%. From Jonathan Turner!

Before this patch we would still link with the system libstdc++. It worked
fine most of the time, but would break if the used headers were a lot newer
than the system libraries.

This patch changes the driver to use the libraries corresponding to the
headers the user selected.

This fixes, for example, using 4.5 headers in a system with gcc 4.1.

This avoids going through all source location entries and fixes the performance regression.
Many thanks to Doug for the hint!

Recreate the DeclContext before adding the implicit friend forward declaration. This should fix the asserting buildbot.

llvm-svn: 132333

For compatibility with MSVC, a friend declaration also act as a forward declaration if the tag name is not already declared. The tag name is declared in the next outermost non record scope.
Example:

class A {
  friend class B;
  B* b;
};
B* global_b;

I tried to use an assert to prove that I could remove each of the
arguments I did, but ended up writing my assert with inverted logic.
Doh! Reported by Xi Wang on cfe-dev. I have manually verified the source
locations and ranges for these using -ast-dump. I tried writing a test
case that would catch these, but these expressions aren't exposed in the
c-index-test's token annotation utility.
