Benjamin Kramer c1ffdab3fb [libclang] Link clang-tidy plugin into libclang if present.
This is a sad workaround for the lack of plugin support in libclang. Depends
on D17807, a tools-extra change that also contains the test case.

This is designed to be easy to remove again if libclang ever grows proper
plugin support.

Benjamin Kramer 8f5eb56df3 [clang-tidy] Add "clang-tidy as a clang plugin" skeleton.
This doesn't really do much at the moment. You can load it via libclang
and set the -checks via an extra command line argument as illustrated in
the test case. Support for other options (including headers check) is
currently missing. Also when using this with libclang some checks may
not work with the precompiled preamble in place.

This can be used to easily show clang-tidy warnings in an editor
integration as all that's needed is adding command line flags that are
passed into libclang. Warnings and FixIts are exposed via the existing
CXDiagnostic machinery.

George Rimar 4cfe572932 [ELF] - add support for relocations against local symbols when producing relocatable output.
There was a known limitation for -r option:
relocations against local symbols were not supported. 
For example rel[a].eh_frame sections contained relocations against sections
and that was not supported for -r before. Patch fixes that.

Alexey Bataev 94a4f0cb5f [OPENMP 4.0] Initial support for 'omp declare reduction' construct.
Add parsing, sema analysis and serialization/deserialization for 'declare reduction' construct.
User-defined reductions are defined as

#pragma omp declare reduction( reduction-identifier : typename-list : combiner ) [initializer ( initializer-expr )]
These custom reductions may be used in 'reduction' clauses of OpenMP constructs. The combiner specifies how partial results can be combined into a single value. The
combiner can use the special variable identifiers omp_in and omp_out that are of the type of the variables being reduced with this reduction-identifier. Each of them will
denote one of the values to be combined before executing the combiner. It is assumed that the special omp_out identifier will refer to the storage that holds the resulting
combined value after executing the combiner.
As the initializer-expr value of a user-defined reduction is not known a priori the initializer-clause can be used to specify one. Then the contents of the initializer-clause
will be used as the initializer for private copies of reduction list items where the omp_priv identifier will refer to the storage to be initialized. The special identifier
omp_orig can also appear in the initializer-clause and it will refer to the storage of the original variable to be reduced.

Tom Stellard cc7067a668 AMDGPU: Insert two S_NOP instructions for every high level source statement.
Patch by: Konstantin Zhuravlyov

Summary: Tools, such as debugger, need to pause execution based on user input (i.e. breakpoint). In order to do this, two S_NOP instructions are inserted for each high level source statement: one before first isa instruction of high level source statement, and one after last isa instruction of high level source statement. Further, debugger may replace S_NOP instructions with S_TRAP instructions based on user input.

Sean Callanan bb33f58a1a Fixed a problem where the ASTImporter mishandled in-class initializers.
Previously, the ASTImporter, when copying a FieldDecl, would make the
new FieldDecl use the exact same in-class initializer as the original
FieldDecl, which is a problem since the initializer is in the wrong AST.
The initializer must be imported, just like all the other parts of the
field.

Doug Gregor reviewed this fix.

Philip Reames 23d933982a [MBP] Avoid placing random blocks between loop preheader and header
If we have a loop with a rarely taken path, we will prune that from the blocks which get added as part of the loop chain. The problem is that we weren't then recognizing the loop chain as schedulable when considering the preheader when forming the function chain. We'd then fall to various non-predecessors before finally scheduling the loop chain (as if the CFG was unnatural.) The net result was that there could be lots of garbage between a loop preheader and the loop, even though we could have directly fallen into the loop. It also meant we separated hot code with regions of colder code.

The particular reason for the rejection of the loop chain was that we were scanning predecessor of the header, seeing the backedge, believing that was a globally more important predecessor (true), but forgetting to account for the fact the backedge precessor was already part of the existing loop chain (oops!.

David Majnemer 1ef654024f [X86] Don't give catch objects a displacement of zero
Catch objects with a displacement of zero do not initialize a catch
object.  The displacement is relative to %rsp at the end of the
function's prologue for x86_64 targets.

If we place an object at the top-of-stack, we will end up wit a
displacement of zero resulting in our catch object remaining
uninitialized.

Address this by creating our catch objects as fixed objects.  We will
ensure that the UnwindHelp object is created after the catch objects so
that no catch object will have a displacement of zero.

Nico Weber 779355f96b Serialize `pragma ms_struct` state.
pragma ms_struct has an effect on struct decls, and the effect is serialized
correctly already.  But the "is ms_struct currently on" state wasn't before
this change.

This uses the same approach as `pragma clang optimize`: When writing a module,
the state isn't serialized, only when writing a pch file.

Jonathan Peyton 283a215c7a Add new OpenMP 4.5 taskloop construct feature
From the standard: The taskloop construct specifies that the iterations of one
or more associated loops will be executed in parallel using OpenMP tasks. The
iterations are distributed across tasks created by the construct and scheduled
to be executed.

This initial implementation uses a simple linear tasks distribution algorithm.
Later we can add other algorithms to speedup generation of huge number of tasks
(i.e., tree-like tasks generation should be faster).

This needs to be put into the OpenMP runtime library in order for the
compiler team to develop the compiler side of the implementation.

Daniel Jasper abd1f57453 clang-format: [JS] Optionally re-quote string literals.
Turns "foo" into 'foo' (or vice versa, depending on configuration).
This makes it more convenient to follow the Google JavaScript style
guide:
https://google.github.io/styleguide/javascriptguide.xml?showone=Strings#Strings

This functionality is behind the option "JavaScriptQuotes", which can be:

  * "leave" (no re-quoting)
  * "single" (change to single quotes)
  * "double" (change to double quotes)

This also changes single quoted JavaScript string literals to be treated
as tok::string_literal, not tok::char_literal, which fixes two unrelated
tests.

Jonathan Peyton 71909c57ca Add new OpenMP 4.5 doacross loop nest feature
From the standard: A doacross loop nest is a loop nest that has cross-iteration
dependence. An iteration is dependent on one or more lexicographically earlier
iterations. The ordered clause parameter on a loop directive identifies the
loop(s) associated with the doacross loop nest.

The init/fini routines allocate/free doacross buffer(s) for each loop for each
thread.  The wait routine waits for a flag designated by the dependence vector.
The post routine sets the flag designated by current iteration vector.  We use
a similar technique of shared buffer indices that covers up to 7 nowait loops
executed simultaneously by different threads (number 7 has no real meaning,
just heuristic value).  Also, the size of structures are kept intact via
reducing dummy arrays.

This needs to be put into the OpenMP runtime library in order for the compiler
team to develop the compiler side of the implementation.
