U?INT{_,_FAST,_LEAST}{8,16,32,64}_{MAX,TYPE}

Clean up this one specifically, as it has the effect of double-spacing
the list of thread stop reasons, and substantially bloats the log file
when opening a core with hundreds of threads.
There are other cases of extra newlines. Some of them do increase
readability, so avoid a general sweep for now.

Rather than having kw___if_exists be a special case of
ParseCompoundStatementBody, we can look for kw___if_exists in the big
switch over for valid statement tokens in ParseStatementOrDeclaration.
Nested __if_exists blocks are used in the DECLARE_REGISTRY_RESOURCEID
macro from atlcom.h.

MSVC does not create a new scope for the body of an __if_exists compound
statement. Clang already gets this right today, but it was untested.

Optimize the codegen of select and branch instructions to directly use the
EFLAGS from the {s|u}{add|sub|mul}.with.overflow intrinsics.

Now that non-leaf ComplexPatterns are allowed we can fold all the MUBUF
store patterns into the instruction definition. We will also be able to
reuse this new ComplexPattern for MUBUF loads and atomic operations.

When a user types:
int [4] foo;
assume that the user means:
int foo[4];
Update the information for 'foo' to prevent additional errors, and provide
a fix-it hint to move the brackets to the correct location.
Additionally, suggest parens for types that require it, such as:
int [4] *foo;
to:
int (*foo)[4];

In assembly the expression a=b is parsed as an assignment, so it should be
printed as one.
This remove a truly horrible hack for producing a label with "a=.". It would
be used by codegen but would never be reached by the asm parser. Sorry I
missed this when it was first committed.

The patch is as is with the functionality left disabled for apple vendors because of performance regressions. If this is enabled it ends up searching for symbols in all shared libraries that are loadeded.

R600 was using a clamped version of rsq, but SI was not. Add a
new rsq_clamped intrinsic and use them consistently.
It's unclear to me from the documentation what behavior
the R600 instructions have, so I assume they have the legacy behavior
described by the SI documents. For R600, use RECIPSQRT_IEEE
for both llvm.AMDGPU.rsq.legacy and llvm.AMDGPU.rsq. R600 also
has RECIPSQRT_FF, which I'm not sure how it fits in here.

process fully reaped. The race & bad behavior was because we were letting
the reaping thread in LLDB to also set the Process exit status, so debugserver
would sometimes be shut down before it got a chance to report the exit status,
and then we got confused.

1) missing iterator bits needed by libstdc++4.7
Using find_if was convenient, but since operator++ wasn't a good
interface anyway, I just replaced with a range-based for loop and
removed operator++ from the directory_iterator class.
2) stop relying on order of iterating real files

Most of this is just tests that were silently succeeding in spite of
schema changes I made over a year ago. Cleaning them up as they lead to
failures in a change I'm working on/will come soon.
test/DebugInfo/2010-01-19-DbgScope.ll was removed as it tested miscoping
where a DebugLoc described a location not in the current function. The
test case doesn't describe why this is a valid situation and should be
supported, so I'm removing it and shortly going to commit changes that
make this firmly unsupported/assert-fail.

PR20071 identifies a problem in PowerPC's fast-isel implementation for
floating-point conversion to integer. The fctiduz instruction was added in
Power ISA 2.06 (i.e., Power7 and later). However, this instruction is being
generated regardless of which 64-bit PowerPC target is selected.
The intent is for fast-isel to punt to DAG selection when this instruction is
not available. This patch implements that change. For testing purposes, the
existing fast-isel-conversion.ll test adds a RUN line for -mcpu=970 and tests
for the expected code generation. Additionally, the existing test
fast-isel-conversion-p5.ll was found to be incorrectly expecting the
unavailable instruction to be generated. I've removed these test variants
since we have adequate coverage in fast-isel-conversion.ll.

According to the x86-64 ABI, structures with both floating point and
integer members are split between floating-point and general purpose
registers, and consecutive 32-bit floats can be packed into a single
floating point register.
In the case of variadic functions these are stored to memory and the position
recorded in the va_list. This was already correctly implemented in
llvm.va_start.
The problem is that the code in clang for implementing va_arg was reading
floating point registers from the wrong location.
Patch by Thomas Jablin.
Fixes PR20018.

The API is based on sys::fs::directory_iterator, but it allows iterating
over overlays and the yaml-based VFS. For now, it isn't used by
anything (except its tests).

With LocTrackingOnly there's no longer a user-facing distinction so the NDEBUG
checks can go away. (Except maybe column info, but -verify only checks line
numbers anyway.)
Also add a RUN line to validate the traditional !LocTrackingOnly case.

r209631: Use MIUtilSystemLinux on FreeBSD as well
We should later rename this file (probably MIUtilSystemPOSIX), but
more clean-up is still needed here, and we can wait until we better
understand how this code may be shared between FreeBSD, Linux, and OS X.
r209632: Add stdlib.h for malloc and friends
r209633: Remove include of obsolete stropts.h header
The header is for POSIX streams functionality, and does not exist on
FreeBSD, OS X, or contemporary Linux distributions.
Issue reported by John Wolfe.

Insert a header into the new testcase containing a sample RUN line a FIXME and
an XFAIL. Then insert the formated C code and finally the LLVM-IR without
attributes, the module ID or the target triple.

than one method with mismatched type of same selector name.
clang issues a warning to point this out since it may cause
undefined behavior. There are cases though that some APIs
don't care about user methods and such warnings are perceived as
noise. This patch allows users to add paren delimiters around
selector name to turn off such warnings. So, @selector((save:)) will
turn off the warning. It also provides 'fixit' so user knows
what to do. // rdar://16458579
