The main motivation is to not require a latex installation when building
the documentation. I would also expect a better image quality and the
ability to copy&paste from formulas with a javascript based solution for
displaying the math.

This caused PR25607 and also caused Chromium to crash on start-up.
(Also had to update test/CodeGen/X86/avx-splat.ll, which was committed
after shrink wrapping was enabled.)

to allow them to explicitly opt into data recursion despite having overridden
Traverse*Stmt or Traverse*Expr. Use this to reintroduce data recursion to the
one place that lost it when DataRecursiveASTVisitor was removed.

In the previous patch (r254003), I made the linker emit PT_GNU_STACK
unconditionally. But sometimes you want to have a control over the
presence of the segment. With this patch, you can omit the segment
by passing -z execstack option.

This script really should not be assuming every subdirectory is
a language directory for swig generation. Using a hack to get
this working for now, but this should be solved once this script
is re-written similar to how prepare_bindings was.

Add a simple initial heuristic to control importing based on the number
of instructions recorded in the function's summary. Add option to
control the limit, and test using option.

Fix buildbot failure for clang-x86_64-linux-selfhost-modules.
http://lab.llvm.org:8011/builders/clang-x86_64-linux-selfhost-modules/builds/8866
The failing test cases are newly added from r254021. It seems the IR has a
different order in this platform. In this patch, I temporarily relax the test
case to make the build green. I'll have a complete fix (more robust way to test)
soon.

When the original binary is executed and sampled, the resulting profile
contains information on the original inline stack. We currently follow
the original inline plan if we notice that the inlined callsite has more
than 0 samples to it.
A better way is to determine whether the callsite is actually worth
inlining. If the callsite accumulates a small fraction of the samples
spent in the parent function, then we don't want to bother inlining it
(as it means that the callsite is actually cold).
This patch introduces a threshold expressed in percentage of samples
in relation to the parent function. If the callsite uses less than N%
of the total samples used by its parent, the original inline decision is
not re-applied.
I've set the threshold to the very arbitrary value of 5%. I'm yet to do
any actual experiments to see what's a good value. I wanted to separate
the basic mechanism from the tuning.

In case a sysroot prefix is configured, and the filename starts with the
'/' character, and the script being processed was located inside the
sysroot prefix, the file's name will be looked for in the sysroot
prefix. Otherwise, the linker falls to the common lookup scheme.

Change origin-alignment test to test only the alignment of the origin
store, and not the exact instruction sequence used to compute the
address. This makes the test less fragile and, in particular, lets it
pass both with the old and new MSan ABIs.

With this patch, the client will package up all the required
inputs into a compressed zip file, establish a connection to the
server, send the input to the server, and wait for the server to
send a response (in this case the response is just echoed back to
the client).
This gets the network communication in place, and in a subsequent
patch I will follow up with the code that actually runs swig on
the server and sends back the output instead of echoing back the
input.

This version supports local generation only. It's intentionally
stupid, and does not support any kind of dependency checking.
If you run the script, it's going to call SWIG. While this is
a slow process, we are going to combine the use of the swig bot
with checked in static bindings, meaning that it won't be terribly
important to only regenerate the bindings when the input files
have actually changed.
A side benefit of this is that the implementation is drastically
simpler.
This is all experimental at the moment, but it duplicates a lot
of the logic currently found in prepare_bindings.py. There was
not a good way to reuse some of the logic without invasive changes
on that script, and since this script is still experimental, it
makes sense to just copy them over, and if / when this becomes
more mature, we can get rid of the other ones.

This patch implements a minimum spanning tree (MST) based instrumentation for
PGO. The use of MST guarantees minimum number of CFG edges getting
instrumented. An addition optimization is to instrument the less executed
edges to further reduce the instrumentation overhead. The patch contains both the
instrumentation and the use of the profile to set the branch weights.

r253918 had refactored expressions like "A - B.Address + C" to "A -
B.getAddressWithOffset(C)". This is incorrect, since the latter really
computes "A - B.Address - C".
None of the tests I can run locally on x86 broke due to this bug, but it
is the current suspect for breakage on the AArch64 buildbots.
llvm-svn: 254017
X86 needs to use its own FMA opcodes, preventing the standard FNEG(FMA) pattern table recognition method used by other platforms. This patch adds support for lowering FNEG(FMA(X,Y,Z)) into a single suitably negated FMA instruction.

This patch adds some fixes for MSAN with libc++ for aarch64:
1. Adds the libmsan_loadable name for aarch64.
2. Fixes some pthread_attr_setstacksize for aarch64, since glibc sets
the mininum stack size to be higher than the x86_64 default (16KB
vs 128KB).
3. Fixes a swprintf null char constant definition.

Analyze imported function bodies and add any new external calls to
the worklist for importing. Currently no controls on the importing
so this will end up importing everything possible in the call tree
below the importing module. Basic profitability checks coming next.
Update test to check for iteratively inlined functions.

This patch fixes the following issues:
1. Fix the return type of X86psadbw: it should not be the same type of inputs.
For vNi8 inputs the output should be vMi64, where M = N/8.
2. Fix the return type of int_x86_avx512_psad_bw_512 accordingly.
3. Fix the definiton of PSADBW, VPSADBW, and VPSADBWY accordingly.
4. Adjust the return type when building a DAG node of X86ISD::PSADBW type.
5. Update related tests.

The new function import pass exposed an issue when we import references
to local values on multiple importing passes. They are renamed on each
import pass, and we need to ensure that the already promoted and renamed
references existing in the dest module are correctly identified and
updated so that they aren't spuriously renamed again (due to a perceived
conflict with the newly linked reference).

The closure is designed to abstact away two types of value profile
data:
- InstrProfRecord which is the primary data structure used to
represent profile data in host tools (reader, writer, and profile-use)
- value profile runtime data structure suitable to be used by C
runtime library.
Both sources of data need to serialize to disk/memory-buffer in common
format: ValueProfData.
The abstraction allows compiler-rt's raw profiler writer to share
the same code with indexed profile writer.

The nullability checker was not suppressing false positives resulting from
inlined defensive checks when null was bound to a nonnull variable because it
was passing the entire bind statement rather than the value expression to
trackNullOrUndefValue().
This commit changes that checker to synactically match on the bind statement to
extract the value expression so it can be passed to trackNullOrUndefValue().

Summary:
Followed the guidelines in:
http://llvm.org/docs/CodingStandards.html#include-style
However, I noticed that uppercase named headers come before lowercase ones
throughout the codebase. So kept them as is.
