Fix broken getAttributeSpellingListIndex for pragma attributes

We noticed when implementing a new pragma that the TableGen-generated function
getAttributeSpellingListIndex() did not work for pragma attributes. It relies
on the values in the enum AttributeList::Syntax and a new value
AS_ContextSensitiveKeyword was added changing the value for AS_Pragma.
Apparently no tests failed since no pragmas currently make use of the
generated function.

To fix this we can move AS_Pragma back to the value that TableGen code expects.
Also to prevent changes in the enum from breaking that routine again I added
calls to getAttributeSpellingListIndex() in the unroll pragma code. That will
cause some lit test failures if the order is changed. I added a comment to
remind of this issue in the future.

This assumes we don’t need/want full TableGen support for

Florian Hahn [Wed, 9 Aug 2017 13:53:28 +0000 (13:53 +0000)]
[ARM] Remove FeatureNoARM implies ModeThumb.

Summary:
By removing FeatureNoARM implies ModeThumb, we can detect cases where a
function's target-features contain -thumb-mode (enables ARM codegen for the
function), but the architecture does not support ARM mode. Previously, the
implication caused the FeatureNoARM bit to be cleared for functions with
-thumb-mode, making the assertion in ARMSubtarget::ARMSubtarget [1]
pointless for such functions.

This assertion is the only guard against generating ARM code for
architectures without ARM codegen support. Is there a place where we
could easily generate error messages for the user? At the moment, we
would generate ARM code for Thumb-only architectures. X86 has the same
behavior as ARM, as in it only has an assertion and no error message,
but I think for ARM an error message would be helpful. What do you
think?

For the example below, `llc -mtriple=armv7m-eabi test.ll -o -` will
generate ARM assembler (or fail with an assertion error with this patch).
Note that if we run the resulting assembler through llvm-mc, we get
an appropriate error message, but not when codegen is handled
through clang.

```
define void @bar() #0 {
entry:
  ret void
}

Benoit Belley [Wed, 9 Aug 2017 13:47:01 +0000 (13:47 +0000)]
[Support] PR33388 - Fix formatv_object move constructor

formatv_object currently uses the implicitly defined move constructor,
but it is buggy. In typical use-cases, the problem doesn't show-up
because all calls to the move constructor are elided. Thus, the buggy
constructors are never invoked.

The issue especially shows-up when code is compiled using the
-fno-elide-constructors compiler flag. For instance, this is useful when
attempting to collect accurate code coverage statistics.

The exact issue is the following:

The Parameters data member is correctly moved, thus making the
parameters occupy a new memory location in the target
object. Unfortunately, the default copying of the Adapters blindly
copies the vector of pointers, leaving each of these pointers
referencing the parameters in the original object instead of the copied
one. These pointers quickly become dangling when the original object is
deleted. This quickly leads to crashes.

The solution is to update the Adapters pointers when performing a move.
The copy constructor isn't useful for format objects and can thus be
deleted.

This resolves PR33388.

[LCG] Switch one of the update methods for the LazyCallGraph to support
limited batch updates.

Specifically, allow removing multiple reference edges starting from
a common source node. There are a few constraints that play into
supporting this form of batching:

1) The way updates occur during the CGSCC walk, about the most we can
   functionally batch together are those with a common source node. This
   also makes the batching simpler to implement, so it seems
   a worthwhile restriction.
2) The far and away hottest function for large C++ files I measured
   (generated code for protocol buffers) showed a huge amount of time
   was spent removing ref edges specifically, so it seems worth focusing
   there.
3) The algorithm for removing ref edges is very amenable to this
   restricted batching. There are just both API and implementation
   special casing for the non-batch case that gets in the way. Once
   removed, supporting batches is nearly trivial.

This does modify the API in an interesting way -- now, we only preserve
the target RefSCC when the RefSCC structure is unchanged. In the face of
any splits, we create brand new RefSCC objects. However, all of the
users were OK with it that I could find. Only the unittest needed
interesting updates here.

How much does batching these updates help? I instrumented the compiler
when run over a very large generated source file for a protocol buffer
and found that the majority of updates are intrinsically updating one
function at a time. However, nearly 40% of the total ref edges removed
are removed as part of a batch of removals greater than one, so these
are the cases batching can help with.

When compiling the IR for this file with 'opt' and 'O3', this patch
reduces the total time by 8-9%.

The publics stream and globals stream are very similar. They both

the symbol record stream. Because of the need for each builder to manage
both an independent hash stream as well as a single shared record
stream, making the two builders be independent entities is not the right

class, which writes all 3 streams at once.

Note that this patch does not contain any functionality change. So we're
still not yet writing any records to the globals stream. All we're doing
is making it so that when we do start writing records to the globals,

[AST] Move visibility computations into a class; NFC

This is patch 1 in a 2 patch series that aims to fix PR29160. Its goal
is to cache decl visibility/linkage for the duration of each
visibility+linkage query.

The simplest way I can see to do this is to put the visibility
calculation code that needs to (transitively) access this cache into a
class, which is what this patch does. Actual caching will come in patch
2. (Another way would be to keep the cache in ASTContext + manually
invalidate it or something, but that felt way too subtle to me.)

Caching visibility results across multiple queries seems a bit tricky,
since the user can add visibility attributes ~whenever they want, and
these attributes can apparently have far-reaching effects (e.g. class
visibility extends to its members, ...). Because a cache that's dropped
at the end of each top-level query seems to work nearly as well and
doesn't require any eviction logic, I opted for that design.

Summary:
This is a pure refactoring change.  It paves the way for OS-specific
implementations, such as Fuchsia's, that can do most of the
per-thread bookkeeping work in the creator thread before the new
thread actually starts.  This model is simpler and cleaner, avoiding
some race issues that the interceptor code for thread creation has
to do for the existing OS-specific implementations.
