Commit 7fb8a40e5220d6d4efa14c15f92b6f28ba1b18f7 by sjoerd.meijer
New intrinsic @llvm.get.active.lane.mask()

This is split off from D79100 and:
- adds a intrinsic description/definition for @llvm.get.active.lane.mask(), and
- describe its semantics in LangRef.

As described (in more detail) in its LangRef section, it is semantically
equivalent to an icmp with the vector induction variable and the back-edge
taken count, and generates a mask of active/inactive vector lanes.

It will have several use cases. First, it will be used by the
ExpandVectorPredication pass for the VP intrinsics, to expand VP intrinsics for
scalable vectors on targets that do not support the `%evl` parameter, see
D78203.

Also, this is part of, and essential for our ARM MVE tail-predication story:
- this intrinsic will be emitted by the LoopVectorizer in D79100, when
  the scalar epilogue is tail-folded into the vector body. This new intrinsic
  will generate the predicate for the masked loads/stores, and it takes the
  back-edge taken count as an argument. The back-edge taken count represents the
  number of elements processed by the loop, which we need to setup MVE
  tail-predication.
- Emitting the intrinsic is controlled by a new TTI hook, see D80597.
- We pick up this new intrinsic in an ARM MVETailPredication backend pass, see
  D79175, and convert it to a MVE target specific intrinsic/instruction to
  create a tail-predicated loop.

[AST][RecoveryExpr] Make DeduceAutoType fail if the auto is deduced from recovery exprs.

Summary:
With recovery-ast, we will get an undeduced `auto` return type for
"auto foo()->undef()" function declaration, the function decl still keeps
valid, it is dangerous, and breaks assumptions in clang, and leads crashes.

This patch invalidates these functions, if we deduce autos from the
return rexpression, which is similar to auto VarDecl.

[lldb] Make "inline" tests more configurable

Summary:
This patch adds two new arguments to the MakeInlineTest function. The
main motivation is a follow-up patch I'm preparing, but they seem
generally useful.

The first argument allows the user to specify the "build dictionary".
With this argument one can avoid the need to provide a custom Makefile
if all he needs is to override a couple of make variables. This hooks in
neatly into the existing dictionary support for non-inline tests.

The second argument specifies the name of the test. This could be used
to provide better names to the generated test classes, but it's mainly
useful in conjuction with the first argument: now that we can specify a
custom build dictionary, it may sometimes make sense to run the same
test twice with different build configurations. To achieve that, we need
to give the two tests different names, and this argument achieves that.

The usage of the arguments is demonstrated via TestBasicEntryValues.py.

Do not list adb devices when a device id is given

Summary:
On Android, this method gets called twice: first when establishing
a host-server connection, then when attaching to a process id.

Each call takes several seconds to finish (especially slower on Windows)
and eliminating the call for the typical case improves latency significantly.

[libc++] Fix the LIBCXX_HAS_MERGED_TYPEINFO_NAMES_DEFAULT setting

When the __config_site header is generated, but LIBCXX_HAS_MERGED_TYPEINFO_NAMES_DEFAULT
wasn't specified, _LIBCPP_HAS_MERGED_TYPEINFO_NAMES_DEFAULT would be defined
to 0, which was the NonUnique RTTI comparison implementation. The intent
was to use the Unique RTTI comparison implementation in that case, which
caused https://llvm.org/PR45549.

Instead, use a proper "switch" to select the RTTI comparison implementation.
Note that 0 can't be used as a value, because that is treated the same
by CMake as a variable that is just not defined.

[clangd] Patch PP directives to use stale preambles while building ASTs

Summary:
Depends on D79930.

This enables more accurate parsing of the AST, by making new macro
definitions in preamble section visible. This is handled by injecting
define directives into preamble patch.

This patch doesn't handle any location mappings yet, so features like go-to-def,
go-to-refs and hover might not work as expected. These will be addressed in a
follow-up patch.

[clangd] locateMacroAt handles patched macros

Summary: Depends on D79992.

This patch changes locateMacroAt to perform #line directive substitution
for macro identifier locations.

We first check whether a location is inside a file included through
built-in header. If so we check whether line directive maps it back to
the main file, and afterwards use TokenBuffers to find exact location of
the identifier on the line.

Instead of performing the mapping in locateMacroAt, we could also store
a mapping inside the ParsedAST whenever we use a patched preamble. But
that would imply adding more responsibility to ParsedAST and paying for
the mapping even when it is not going to be used.

====

Go-To-Definition:

Later on these locations are used for serving go-to-definition requests,
this enables jumping to definition inside the preamble section in
presence of patched macros.

=====

Go-To-Refs:

Macro references in main file are collected separetely and stored as a
map from macro's symbol id to reference ranges. Those ranges are
computed inside PPCallbacks, hence we don't have access to TokenBuffer.

In presence of preamble patch, any reference to a macro inside the
preamble section will unfortunately have the wrong range. They'll point
into the patch rather than the main file. Hence during findReferences,
we won't get any ranges reported for those.

Fixing those requires:
- Lexing the preamble section to figure out "real range" of a patched
  macro definition
- Postponing range/location calculations until a later step in which we
  have access to tokenbuffers.

This patch trades some accuracy in favor of code complexity. We don't do
any patching for references inside the preamble patch but get any
reference inside the main file for free.

[SCCP] Switch to widen at PHIs, stores and call edges.

Currently SCCP does not widen PHIs, stores or along call edges
(arguments/return values), but on operations that directly extend ranges
(like binary operators).

This means PHIs, stores and call edges are not pessimized by widening
currently, while binary operators are. The main reason for widening
operators initially was that opting-out for certain operations was
more straight-forward in the initial implementation (and it did not
matter too much, as range support initially was only implemented for a
very limited set of operations.

During the discussion in D78391, it was suggested to consider flipping
widening to PHIs, stores and along call edges. After adding support for
tracking the number of range extensions in ValueLattice, limiting the
number of range extensions per value is straight forward.

This patch introduces a MaxWidenSteps option to the MergeOptions,
limiting the number of range extensions per value. For PHIs, it seems
natural allow an extension for each (active) incoming value plus 1. For
the other cases, a arbitrary limit of 10 has been chosen initially. It would
potentially make sense to set it depending on the users of a
function/global, but that still needs investigating. This potentially
leads to more state-changes and longer compile-times.

The results look quite promising (MultiSource, SPEC):

[lit] Add an option to print all features used in tests

Lit test suites can tend to accumulate annotations that are not necessarily
relevant as time goes by, for example XFAILS on old compilers or platforms.
To help spot old annotations that can be cleaned up, it can be useful to
look at all features used inside a test suite.

This commit adds a new Lit option '--show-used-features' that prints all
the features used in XFAIL, REQUIRES and UNSUPPORTED of all tests that
are discovered.

[SelectionDAG] Update getNode asserts for EXTRACT/INSERT_SUBVECTOR.

Summary:
The description of EXTACT_SUBVECTOR and INSERT_SUBVECTOR has been
changed to accommodate scalable vectors (see ISDOpcodes.h). This
patch updates the asserts used to verify these requirements when
using SelectionDAG's getNode interface.

This patch introduces the MVT function getVectorMinNumElements
that can be used against fixed-length and scalable vectors when
only the known minimum vector length is required.

[clangd] Run PreambleThread in async mode behind a flag

Summary: Depends on D80198.

This patch implies ASTs might be built with stale preambles without
blocking for a fresh one. It also drops any guarantees on every preamble
version being built. In case of multiple preamble build requests, in
addition to being debounced.

Any preamble requested with a WantDiags::Yes will always be built, this
is ensured by blocking enqueueing of any subsequent reqest.

AST worker will still block for initial preamble to reduce duplicate
work.

[mlir][Linalg][Vector] Add forwarding patterns between linalg.copy and vector.transfer

This revision adds custom rewrites for patterns that arise during linalg structured
ops vectorization. These patterns allow the composition of linalg promotion,
vectorization and removal of redundant copies.

The patterns are voluntarily limited and restrictive atm.
More robust behavior will be implemented once more powerful side effect modeling and analyses are available on view/subview.

On the transfer_read side, the following pattern is rewritten:
```
   %alloc = ...
   [optional] %view = std.view %alloc ...
   %subView = subview %allocOrView ...
   [optional] linalg.fill(%allocOrView, %cst) ...
   ...
   linalg.copy(%in, %subView) ...
   vector.transfer_read %allocOrView[...], %cst ...
```
into
```
   [unchanged] %alloc = ...
   [unchanged] [optional] %view = std.view %alloc ...
   [unchanged] [unchanged] %subView = subview %allocOrView ...
   ...
   vector.transfer_read %in[...], %cst ...
```

On the transfer_write side, the following pattern is rewriten:
```
   %alloc = ...
   [optional] %view = std.view %alloc ...
   %subView = subview %allocOrView...
   ...
   vector.transfer_write %..., %allocOrView[...]
   linalg.copy(%subView, %out)
```

[DAGComb] Do not turn insert_elt into shuffle for single elt vectors.

Currently combineInsertEltToShuffle turns insert_vector_elt into a
vector_shuffle, even if the inserted element is a vector with a single
element. In this case, it should be unlikely that the additional shuffle
would be more efficient than a insert_vector_elt.

Additionally, this fixes a infinite cycle in DAGCombine, where
combineInsertEltToShuffle turns a insert_vector_elt into a shuffle,
which gets turned back into a insert_vector_elt/extract_vector_elt by
a custom AArch64 lowering (in visitVECTOR_SHUFFLE).

Such insert_vector_elt and extract_vector_elt combinations can be
lowered efficiently using mov on AArch64.

There are 2 test changes in arm64-neon-copy.ll: we now use one or two
mov instructions instead of a single zip1. The reason that we need a
second mov in ins1f2 is that we have to move the result to the result
register and is not really related to the DAGCombine fold I think.
But in any case, on most uarchs, mov should be cheaper than zip1. On a
Cortex-A75 for example, zip1 is twice as expensive as mov
(https://developer.arm.com/docs/101398/latest/arm-cortex-a75-software-optimization-guide-v20)

[clang] [Darwin] Add reverse mappings for aarch64/aarch64_32 to darwin arch names

These are mapped in MachO::getMachOArchName already, but were missing
in ToolChain::getDefaultUniversalArchName.

Having these reverse mapped here fixes weird inconsistencies like
-dumpmachine showing a target triple like "aarch64-apple-darwin",
while "clang -target aarch64-apple-darwin" didn't use to work (ended
up mapped as unknown-apple-ios).

Rename APIs in unittests/AST/Language.h in preparation to share them

Summary:
Declaring these helpers in the ast_matcher namespace in the clangAST
unit test seems inappropriate -- neither these helpers, nor clangAST have
anything to do with AST matchers. Therefore, I moved these helpers to
the clang namespace.

Declaring another typedef called "ArgVector" is not a good idea -- we
already have both "ArgVector", "ArgsVector", and "ArgList". I expanded
it into the underlying type.

Declaring another enum called "Language" is not a good idea because we
arleady have the "clang::Language" enum. I renamed it to
"TestLanguage".

Similarly, I renamed "getBasicRunOptionsForLanguage" to
"getCommandLineArgsForTesting" to explain the semantics better (what are
"run options"?) and not repeat types in the function name
("ForLanguage").
