Douglas Gregor 092bad1a39 CMake: Unbreak separated LLVM/Clang project builds for Xcode.
The separate Xcode project generated for Clang is putting the clang
executables into the same location where the LLVM executables are
going. This is wrong, and breaks the Clang build because we try to
create clang++ and clang-cl symlinks in the wrong place and to the
wrong place.

As a stop-gap to get these builds working again, teach the symlink
generation to point into the LLVM executable directory instead.

Alp Toker 383d2c478c ExpectAndConsume: Diagnose errors automatically
1) Teach ExpectAndConsume() to emit expected and expected-after diagnostics
    using the generic diagnostic descriptions added in r197972, eliminating another
    set of trivial err_expected_* variations while maintaining existing behaviour.

 2) Lift SkipUntil() recovery out of ExpectAndConsume(). The Expect/Consume
    family of functions are primitive parser operations that now have the
    well-defined property of operating on single tokens. Factoring out recovery
    exposes opportunities for more consistent and tailored error recover at the
    call sites instead of just relying on a bottled SkipUntil formula.

NAKAMURA Takumi baa9f533fe [CMake][VS][XCode] Restruct the output directory layout more comfortable, ${BINARY_DIR}/${BUILD_MODE}/(bin|lib)
We have been seeing nasty directory layout with CMake multiconfig, such as,
  bin/Release/clang.exe
  lib/clang/3.x/...
  lib/Release/clang/3.x/.. (duplicated)

Move the layout similar to autoconf's;
  Release/bin/clang.exe
  Release/lib/clang/3.x/...

Checked on Visual Studio 10. Could you guys please confirm my change on XCode(and other multiconfig builders)?

Note: Don't set variables CMAKE_*_OUTPUT_DIRECTORY any more, or a certain builder, for eaxample, msbuild.exe, would be confused.

Thisadds a new warning that warns on code like this:

The warning looks like:

test4.cc:5:30: warning: size argument in 'memcmp' call is a comparison [-Wmemsize-comparison]
  if (memcmp(a, b, sizeof(a) != 0))
                   ~~~~~~~~~~^~~~
test4.cc:5:7: note: did you mean to compare the result of 'memcmp' instead?
  if (memcmp(a, b, sizeof(a) != 0))

                            )

  if (memcmp(a, b, sizeof(a) != 0))
                   ^
                   (size_t)(     )
1 warning generated.

This found 2 bugs in chromium and has 0 false positives on both chromium and
llvm.

The idea of triggering this warning on a binop in the size argument is due to
rnk.

Introduce proper facilities to render token spellings using the diagnostic
formatter.

Replaces most of the hard-coded diagnostic messages related to expected tokens,
which all shared the same semantics but had to be multiply defined due to
variations in token order or quote marks.

The associated parser changes are largely mechanical but they expose
commonality in whole chunks of the parser that can now be factored away.

This commit uses C++11 typed enums along with a speculative legacy fallback
until the transition is complete.

This was setting a bad example. DiagIDs are a limited resource and the message

Richard Trieu 2f024f432d Add -Winfinite-recursion to Clang
This new warning detects when a function will recursively call itself on every
code path though that function.  This catches simple recursive cases such as:

void foo() {
  foo();
}

As well as more complex functions like:

void bar() {
  if (test()) {
    bar();
    return;
  } else {
    bar();
  }
  return;
}

This warning uses the CFG.  As with other CFG-based warnings, this is off
by default.  Due to false positives, this warning is also disabled for
templated functions.

Nico Weber 7607fce112 Don't mark record decls invalid when one of its methods is invalid, PR18284.
Without this patch, record decls with invalid out-of-line method delcs would
sometimes be marked invalid, but not always.  With this patch, they are
consistently never marked invalid.

(The code to do this was added in
http://lists.cs.uiuc.edu/pipermail/cfe-commits/Week-of-Mon-20100809/033154.html
, but the test from that revision is still passing.)

As far as I can tell, this was the only place where a class was marked invalid
after its definition was complete.

Reid Kleckner b60a3d5bc1 Eliminate the ItaniumVTableContext object from CodeGenVTables
Now CodeGenVTables has only one VTableContext object, which is either
Itanium or Microsoft.

Fixes a FIXME with no functionality change intended.

Ideally we could avoid the downcasts by pushing the things that
reference the Itanium vtable context into ItaniumCXXABI.cpp, but we're
not there yet.

David Blaikie 3275dc4586 DebugInfo: Do not include implicit members (implicit special members, template instantiations, etc) in the list of members of a structure.
These members will still be lazily added to the relevant DWARF DIEs in
LLVM but when enumerating the members they will not appear. This allows
DWARF type units to be more consistent - the type unit will never
contain these special members (so all instances of the type should have
the same DIEs without some having some special members and others having
others) and the special members will be added to the skeletal
declaration that appears in the relevant compile_unit.

Reid Kleckner d2d1cc5156 Compare canonical return types when generating MS C++ ABI vtable thunks
This was part of the cause for PR17655.  We were generating thunks when
we shouldn't have.  I suspect that if we tweak the test case for PR17655
to actually require thunks, we can reproduce the same crash.

Daniel Jasper 92669ee45c Enable layering check in unavailable modules.
If a header file belonging to a certain module is not found on the
filesystem, that header gets marked as unavailable. Now, the layering
warning (-fmodules-decluse) should still warn about headers of this
module being wrongfully included. Currently, headers belonging to those
modules are just treated as not belonging to modules at all which means
they can be included freely from everywhere.

To implement this (somewhat) cleanly, I have moved most of the layering
checks into the ModuleMap. This will also help with showing FixIts
later.
