Symbol occurrences store the results of local rename and will also be used for
the global, indexed rename results. Their kind is used to determine whether they
should be renamed automatically or not. They can be converted to a set of

Summary:
clang-format wraps object literal keys in an object literal if they are
marked as `TT_SelectorName`s and/or the colon is marked as
`TT_DictLiteral`. Previously, clang-format would accidentally work
because colons in type aliases were marked as `TT_DictLiteral`. r310367
fixed this to assing `TT_JsTypeColon`, which broke wrapping in certain
situations. However the root cause was that clang-format incorrectly
didn't skip questionmarks when detecting selector name.
This change fixes both locations to (1) assign `TT_SelectorName` and (2)
treat `TT_JsTypeColon` like `TT_DictLiteral`.
Previously:
type X = {
a: string, b?: string,
};
Now:
type X = {
a: string,
b?: string,
};

Summary:
In JavaScript, may keywords can be used in method names and thus call sites:
foo.delete();
foo.instanceof();
clang-format would previously insert whitespace after the `instanceof`. This
change generically skips inserting whitespace between a keyword and a
parenthesis if preceded by a dot, i.e. in a callsite.

According to the X86ISelLowering.h, UMUL results are low, high, and flags. But this place was treating result 1 or 2 as flags.
Differential Revision: https://reviews.llvm.org/D36654
llvm-svn: 310846
Summary:
The flag result is an i32 type. But its only really used for connectivity. I don't think anything even assumes a particular format. We don't ever do any real operations on it. So known bits don't help us optimize anything.
My main motivation is that the UMUL behavior is actually wrong. I was going to fix this in D36654, but then realized there was just no reason for it to be here.

The assert was added with r310779 and is usually correct,
but as the test shows, not always. The 'volatile' on the
load is needed to expose the faulty path because without
it, DemandedBits would return that the load is just dead
rather than not demanded, and so we wouldn't hit the
bogus assert.
Also, since the lambda is just a single-line now, get rid
of it and inline the DB.isAllOnesValue() calls.
This should fix (prevent execution of a faulty assert):

Summary:
On platforms with `getrandom`, the system call defaults to blocking. This
becomes an issue in the very early stage of the boot for Scudo, when the RNG
source is not set-up yet: the syscall will block and we'll stall.
Introduce a parameter to specify that the function should not block, defaulting
to blocking as the underlying syscall does.
Update Scudo to use the non-blocking version.

This adjusts the tests to hopfully pacify the llvm-clang-x86_64-expensive-checks-win
buildbot.
Unlike many other instructions, these instructions have aliases which
take coprocessor registers, gpr register, accumulator (and dsp accumulator)
registers, floating point registers, floating point control registers and
coprocessor 2 data and control operands.
For the moment, these aliases are treated as pseudo instructions which are
expanded into the underlying instruction. As a result, disassembling these
instructions shows the underlying instruction and not the alias.

Summary:
This patch adds the -path-equivalence option (example: llvm-cov show -path-equivalence=/origin/path,/local/path) which maps the source code path from one machine to another when using `llvm-cov show`. This is similar to the -filename-equivalence option, but doesn't require you to specify all the source files on the command line.
This allows you to generate the coverage data on one machine (e.g. in a CI system), and then use llvm-cov on another machine where you have the same code base on a different path.

On some targets, the penalty of executing runtime unrolling checks
and then not the unrolled loop can be significantly detrimental to
performance. This results in the need to be more conservative with
the unroll count, keeping a trip count of 2 reduces the overhead as
well as increasing the chance of the unrolled body being executed. But
being conservative leaves performance gains on the table.
This patch enables the unrolling of the remainder loop introduced by
runtime unrolling. This can help reduce the overhead of misunrolled
loops because the cost of non-taken branches is much less than the
cost of the backedge that would normally be executed in the remainder
loop. This allows larger unroll factors to be used without suffering
performance loses with smaller iteration counts.

Moreover, the patch *deleted* the flag in addition to changing the
default, and links to a code review that doesn't even discuss the flag
and just has an update to a Clang test case.
I've followed up on the commit thread to ask for numbers on compile time
at this point, leaving the flag in place until things stabilize, and
pointing at specific code that seems to exhibit excessive compile time
with this patch.

Summary:
In Python 2, calling `dict.items()` returns an indexable `list`, whereas
on Python 3 it returns a set-like `dict_items` object, which cannot be
indexed. Explicitly onvert the `dict_items` object so that it can be
indexed when using Python 3.
In combination with D36622, D36623, and D36624, this change allows
`opt-viewer.py` to exit successfully when run with Python 3.4.
Test Plan:
Run `opt-viewer.py` using Python 3.4 and confirm it does not encounter a
runtime error when when indexing into `dict.items()`.

There appears to be a bug where the generated code to extract the sign
bit doesn't work correctly for 32-bit inputs. I've replied to the
original commit pointing out the problem. I think I see by inspection
(and reading the manual for PPC) how to fix this, but I can't be 100%
confident and I also don't know what the best way to test this is.
Currently it seems nearly impossible to get the backend to hit this code
path, but the patch autohr is likely in a better position to craft such
test cases than I am, and based on where the bug is it should be easily
done.

Summary:
These functions were overly complicated. The body of this function was rechecking for an And operation to find the constant, but we already knew we were looking at two Ands ORed together and the pieces are in variables. We already had earlier nearby code that checked for ConstantInts. So just inline the remaining parts into the earlier code.
Next step is to use m_APInt instead of ConstantInt.
