This is really ugly, but it is no worse than what we have in clang right now and
it is better to get it working first and clean/optimize it afterwards.
Will be tested from clang in the next patch.

Use castAs<> where appropriate. Don't check conditionals which are
always true. Delete a bit of dead code. Reindent a bunch of code which
is no longer guarded by an if statement.

through Bill's patch:
1) Correctly test the file descriptor after the sceond attempt at
creating the file.
2) Make the filename a global so that we can issue error messages from
other routines.
3) Check errno in several places and print it out so that errors are
easier to track down.
I don't really expect any of these to fix the current failures I'm
seeing, but I'm hopeful they'll at least let me debug them.

We really need the C standard library to be available to implement the
profiling runtime library reasonably, and replicating everything in the
SDKs tree really isn't addressing any problems we have. Notably, all of
the sanitizer runtimes take the same approach, and this isn't a library
which could end up in a bootstrapping problem where the system headers
aren't even available.
This will hopefully prevent subsequent changes which start using various
other bits of C standard library to make things more debuggable.

command line. Change the darwin universal binary options to
be TargetCommonOpts so that they'll be passed to the linker since
-arch at least is still needed.
Someone on darwin with a buildit based build should probably verify
that this doesn't break anything there.

-performSelector: and friends return a value that is boxed as an Objective-C
pointer. Sometimes it is an Objective-C pointer, sometimes it isn't.
Some clients may wish to silence this warning based on calling
this method.

This is a large test and thus it will only run if you pass in --param
run_long_tests=trueto LIT. This is intended so that this test can run on
buildbots and not when one runs make check.
llvm-svn: 184787
This will prevent the tests from running on normal make check. You will need to
actually pass in --param run_long_tests=true to LIT in order to run these.

The top-level hash is used to determine if we need to update the global code-completion results.
ImportDecls did not affect the hash so a newly introduced ImportDecl would not trigger an update of the global results.

This changes the mangling of local static variables/etc. inside blocks
to do something simple and sane. This avoids depending on the way we mangle
blocks, which isn't really appropriate here.
John, please take a look at this to make sure the mangling I chose is sane.
Fixes <rdar://problem/14074423>.

At this point, it's clear that the MSVC mangler uses the type-as-written
instead of the canonical type, so this should bring us closer to MSVC.
The main thrust of this change is to fix the way we mangle decayed array
parameters of function pointer parameters. With a DecayedType sugar
node, this code can now be much simpler.
Fixes PR16096.
This also fixes a separate issue that Richard spotted in review.
Because separate declarations of the same entity can be spelled and
mangled differently, MSVC always mangles the earliest declaration in an
attempt to avoid link errors. Clang now does the same.

The way we decide which file to remove is fairly odd. I took a quick look at
maybe changing that, but it would be a more work than I want to put at this

We should probably also return rather than

The goal of this sugar node is to be able to look at an arbitrary
FunctionType and tell if any of the parameters were decayed from an
array or function type. Ultimately this is necessary to implement
Microsoft's C++ name mangling scheme, which mangles decayed arrays
differently from normal pointers.

Representing enumerators by int64 instead of uint64 for now. At some

depending on the specific enumeration.

This adds support for the predicted forms of branches (+/-).
There are three cases to consider:
- Branches using a PPC::Predicate code
For these, I've added new PPC::Predicate codes corresponding
to the BO values for predicted branch forms, and updated insn
printing to print them correctly. I've also added new aliases
for the asm parser matching the new forms.
- bt/bf
I've added new aliases matching to gBC etc.
- bd(n)z variants
I've added new instruction patterns for the predicted forms.
In all cases, the new patterns are used for the asm parser only.
(The new infrastructure ought to be sufficient to allow use by
the compiler too at some point.)
