The original commit was reverted in r187640 after it broke the Mac build.
This should now be fixed, by Clang r187668, LLVM r187675, and putting
a -- before %s in the test.

- pull out function to drill to the CXXRecordDecl from the type,
to allow recursive resolution
- make the analysis more robust by rather skipping values we don't
understand

We already reject flags that don't have the CC1Option flag,
but we would previously do so after parsing the command-line
arguments.
Since the option parser now has a parameter for excluding options,
we should just use that instead.

We seem to have ended up with both an inlined check of permitted NEON base
types and a call to a function.
Since the outer if was (I believe) strictly weaker than the one in the
function, there's no actual user-visible behaviour change, so no tests.

It broke the "phase1 - sanity" buildbot. Reverting until
we can figure out what's going on.
And Eric says it broke all current Mac builds actually.

in one module but is only declared as a friend in another module, keep it
visible in the result of the merge.
This is incomplete on two axes:
1) Our handling of local extern declarations is basically broken (we put them
in the wrong decl context, and don't find them in redeclaration lookup, unless
they've previously been declared), and this results in them making friends
visible after a merge.
2) Eventually we'll need to mark that this has happened, and more carefully
check whether a declaration should be visible if it was only visible in some
of the modules in which it was declared. Fortunately it's rare for the
identifier namespace of a declaration to change along its redeclaration chain.

This adds a bunch of options to clang-cl. Notably, this includes
all the options that get passed when doing a default build of a
command-line project with msbuild.exe in Debug and Release modes,
and I believe all flags from Reid's original patch.

We process autorelease counts when we exit functions, but if there's an
issue in a synthesized body the report will get dropped. Just skip the
processing for now and let it get handled when the caller gets around to
processing autoreleases.
(This is still suboptimal: objects autoreleased in the caller context
should never be warned about when exiting a callee context, synthesized
or not.)
Second half of <rdar://problem/14611722>
llvm-svn: 187625
Much of our diagnostic machinery is set up to assume that the report
end path location is valid. Moreover, the user may be quite confused
when something goes wrong in our BodyFarm-synthesized function bodies,
which may be simplified or modified from the real implementations.
Rather than try to make this all work somehow, just drop the report so
that we don't try to go on with an invalid source location.
Note that we still handle reports whose /paths/ go through invalid
locations, just not those that are reported in one.
We do have to be careful not to lose warnings because of this.
The impetus for this change was an autorelease being processed within
the synthesized body, and there may be other possible issues that are
worth reporting in some way. We'll take these as they come, however.

This unifies the unix and windows versions of FileManager::UniqueDirContainer
and FileManager::UniqueFileContainer by using UniqueID.
We cannot just replace "struct stat" with llvm::sys::fs::file_status, since we
want to be able to construct fake ones, and file_status has different members
on unix and windows.
What the patch does is:
* Record only the information that clang is actually using.
* Use llvm::sys::fs::status instead of stat and fstat.
* Use llvm::sys::fs::UniqueID
* Delete the old windows versions of UniqueDirContainer and
UniqueFileContainer since the "unix" one now works on windows too.

Without an ODR, the -flimit-debug-info debug info size optimization of
emitting declarations for fully defined types when only a declaration is
needed by the TU, is incorrect. Emit the full definition whenever it's
available in non-C++.
llvm-svn: 187611
We emit definitions with no members when a nested type is
referenced/required (GCC does the same, to be fair) but failed to attach
the template arguments in such a case.

(I'm not sure how to test this because the Driver will still accept
e.g. "-O4foo", but it goes in the catch-all -O option instead of -O4.)

Before:
template <bool B, bool C>
class A {
static_assert(B &&C, "Something is wrong");
};
After:
template <bool B, bool C>
class A {
static_assert(B && C, "Something is wrong");
};
(Note the spacing around '&&'). Also change the identifier table to always
understand all C++11 keywords (which seems like the right thing to do).

Previously a 2-bit mask was used to mask each element of a vec6 mask before doing the extracts instead of 3-bit mask necessary to cover 0-5. vec3 was the only non-power-of-2 that worked correctly because a +1 conditionally added before calculating floor(log2(elements)).

We would disallow the case where the overloaded member expression is
coming from an address-of operator but we wouldn't issue any diagnostics
when the overloaded member expression comes by way of a function to
pointer decay cast.

ParseCXXClassMemberDeclaration was trying to use the result of
ActOnCXXMemberDeclarator to attach it to some late parsed attributes.
However when failures arise, we have no decl to attach to which
eventually leads us to a NULL pointer dereference.
While we are here, clean up the code a bit.
Fixes PR16765

With this patch, clang-format can be configured to:
* not indent in namespace at all (former behavior).
* indent in namespace as in other blocks.
* indent only in inner namespaces (as required by WebKit style).
Also fix alignment of access specifiers in WebKit style.

This adds a few more clang-cl options. It also exposes two core clang
options to the clang-cl mode: we need to be able to claim --driver_mode
so it doesn't show up as unused in cl mode, and we need -### for tests.

is that the command is quoted differently from the arguments. The
command has '\' and the argument has '\\'. This is made unclear because
FileCheck escapes the single matched '\' when it prints the contents of
the variable, thus fooling me into thinking it had matched '\\' as
intended. The solution is to bind the gcc_install variable in the
argument list rather than out of the command. To do so we also have to
be a bit more careful so that we don't get stray other things into the
'.*' regex.
Also, because of the argument difference, '\\\\' is the correct
formulation before crtbegin, go back to that.

Clang when linking and using a GCC installation from a GCC
cross-compiler.
This was desired already by two special case platforms (Android and
Mips), and turns out to be generally (if frustratingly) true. I've added
a substantial comment to the code clarifying the underlying assumptions
of doing actual cross compiles with Clang (or GCC for that matter!) and
help avoid further confusion here.
The end result is to realize that fully general form of PR12478 cannot
be resolved while we support existing cross-compiling GCC toolchains,
and linking with them (namely, linking against their libgcc and
libstdc++ installs). GCC installs these target libraries under
a target-specific prefix but one that may not be available within the
actual sysroot in use. When linking in this world, GCC works and Clang
should as well, but caveat emptor: DSOs from this tree must be
replicated and rpath-fixed to be found at runtime within the sysroot.
I've extended the cross compile test cases to cover these issues by
pointing them at a sysroot and actually checking the library search
paths.

on the system, and report it when running the driver in verbose mode.
Without this it is essentially impossible to understand why a particular
GCC toolchain is used by Clang for libstdc++, libgcc, etc.
This also required threading a hook through the toolchain layers for
a specific toolchain implementation to print custom information under
'clang -v'. The naming here isn't spectacular. Suggestions welcome.

The quotes (from r187330) didn't really help here, the trick was to disable
the test on MSYS builds. This removes those quotes, changes back the comment
to explain why /? has to be quoted specifically, and moves the REQUIRES
line to the top of the file because that's important.

On windows, c:foo is a valid file path, but stat fails on just "c:". This
causes a problem for clang since its file manager wants to cache data about
the parent directory.
There are refactorings to be done in here, but this gives clang the correct
behavior and testing first.

Beginning with svn r186971, we noticed an internal test started to fail when
using clang built with LTO. After much investigation, it turns out that there
are no blatant bugs here, we are just running out of stack space and crashing.
Preprocessor::ReadFunctionLikeMacroArgs already has one vector of 64 Tokens,
and r186971 added another. When built with LTO, that function is inlined into
Preprocessor::HandleMacroExpandedIdentifier, which for our internal test is
invoked in a deep recursive cycle. I'm leaving the original 64 Token vector
alone on the assumption that it is important for performance, but the new
FixedArgTokens vector is only used on an error path, so it should be OK if it
requires additional heap storage. It would be even better if we could avoid
the deep recursion, but I think this change is a good thing to do regardless.
