Thomas Lively b198b9b897 [WebAssembly] Fix argument types in SIMD narrowing intrinsics
The builtins were updated to take signed parameters in 627a526955, but the
intrinsics that use those builtins were not updated as well. The intrinsic test
did not catch this sign mismatch because it is only reported as an error under
-fno-lax-vector-conversions.

This commit fixes the type mismatch and adds -fno-lax-vector-conversions to the
test to catch similar problems in the future.

[amdgpu-arch] Fix rpath to run from build dir

Prior to this, amdgpu-arch has RUNPATH set to $ORIGIN/../lib which works
for some installs, but not from the build directory where clang executes
the tool from when running tests.

This cmake option adds the location of the rocr runtime to the RUNPATH
(note, it amends RUNPATH here, despite the cmake option referring to RPATH)
to create a binary that runs from build or install location.

Before:
RUNPATH [$ORIGIN/../lib]

RUNPATH [$ORIGIN/../lib:$HOME/llvm-install/lib]

Eliza Velasquez ec725b307f [clang-format] Fix C# nullable-related errors
This fixes two errors:

Previously, clang-format was splitting up type identifiers from the
nullable ?. This changes this behavior so that the type name sticks with
the operator.

Additionally, nullable operators attached to return types in interface
functions were not parsed correctly. Digging deeper, it looks like
interface bodies were being parsed differently than classes and structs,
causing MustBeDeclaration to be incorrect for interface members. They
now share the same logic.

One other change is reintroducing the CSharpNullable type independent of
JsTypeOptionalQuestion. Despite having a similar semantic purpose, their
actual syntax differs quite a bit.

Johannes Doerfert df729e2b82 [OpenMP] Overhaul `declare target` handling
This patch fixes various issues with our prior `declare target` handling
and extends it to support `omp begin declare target` as well.

This started with PR49649 in mind, trying to provide a way for users to
avoid the "ref" global use introduced for globals with internal linkage.
From there it went down the rabbit hole, e.g., all variables, even
`nohost` ones, were emitted into the device code so it was impossible to
determine if "ref" was needed late in the game (based on the name only).
To make it really useful, `begin declare target` was needed as it can
carry the `device_type`. Not emitting variables eagerly had a ripple
effect. Finally, the precedence of the (explicit) declare target list
items needed to be taken into account, that meant we cannot just look
for any declare target attribute to make a decision. This caused the
handling of functions to require fixup as well.

I tried to clean up things while I was at it, e.g., we should not "parse
declarations and defintions" as part of OpenMP parsing, this will always
break at some point. Instead, we keep track what region we are in and
act on definitions and declarations instead, this is what we do for
declare variant and other begin/end directives already.

Highlights:
  - new diagnosis for restrictions specificed in the standard,
  - delayed emission of globals not mentioned in an explicit
    list of a declare target,
  - omission of `nohost` globals on the host and `host` globals on the
    device,
  - no explicit parsing of declarations in-between `omp [begin] declare
    variant` and the corresponding end anymore, regular parsing instead,
  - precedence for explicit mentions in `declare target` lists over
    implicit mentions in the declaration-definition-seq, and
  - `omp allocate` declarations will now replace an earlier emitted
    global, if necessary.

---

Notes:

The patch is larger than I hoped but it turns out that most changes do
on their own lead to "inconsistent states", which seem less desirable
overall.

After working through this I feel the standard should remove the
explicit declare target forms as the delayed emission is horrible.
That said, while we delay things anyway, it seems to me we check too
often for the current status even though that is often not sufficient to
act upon. There seems to be a lot of duplication that can probably be
trimmed down. Eagerly emitting some things seems pretty weak as an
argument to keep so much logic around.

Juneyoung Lee 8a156d1c27 [InstCombine] Fully disable select to and/or i1 folding
This is a patch that disables the poison-unsafe select -> and/or i1 folding.

It has been blocking D72396 and also has been the source of a few miscompilations
described in llvm.org/pr49688 .
D99674 conditionally blocked this folding and successfully fixed the latter one.
The former one was still blocked, and this patch addresses it.

Note that a few test functions that has `_logical` suffix are now deoptimized.
These are created by @nikic to check the impact of disabling this optimization
by copying existing original functions and replacing and/or with select.

I can see that most of these are poison-unsafe; they can be revived by introducing
freeze instruction. I left comments at fcmp + select optimizations (or-fcmp.ll, and-fcmp.ll)
because I think they are good targets for freeze fix.

This removes this dependency during construction. In a perfect world,
MCObjectFileInfo wouldn't depend on MCContext at all, but only be stored in the

This also shifts/adds more information to the MCContext making it more

assemble (linker when -c is not present). However, this phase

arrives into following situation,

 compile (device) ---> offload ---> offload

without -c the chain looks like,
 compile (device) ---> offload ---> linker (device)
				---> offload

The former situation creates an unhandled case which causes
problem. The solution presented in this patch delays the D96769
logic until job creation time. This keeps the offload action

Leonard Chan 84c4754372 [clang] Add -fc++-abi= flag for specifying which C++ ABI to use
This implements the flag proposed in RFC
http://lists.llvm.org/pipermail/cfe-dev/2020-August/066437.html.

The goal is to add a way to override the default target C++ ABI through a

C++ ABIs through compile flags rather than build flags.

In this patch:

- Store -fc++-abi= in a LangOpt. This isn't stored in a CodeGenOpt because
  there are instances outside of codegen where Clang needs to know what the
  ABI is (particularly through ASTContext::createCXXABI), and we should be
  able to override the target default if the flag is provided at that point.
- Expose the existing ABIs in TargetCXXABI as values that can be passed
  through this flag.
  - Create a .def file for these ABIs to make it easier to check flag values.
  - Add an error for diagnosing bad ABI flag values.

Arthur Eubanks d14d84af2f [NewPM] Only invalidate modified functions' analyses in CGSCC passes
Previously, any change in any function in an SCC would cause all
analyses for all functions in the SCC to be invalidated. With this
change, we now manually invalidate analyses for functions we modify,
then let the pass manager know that all function analyses should be
preserved.

So far this only touches the inliner, argpromotion, funcattrs, and
updateCGAndAnalysisManager(), since they are the most used.

Aaron Puchert daca6edb31 Thread safety analysis: Fix false negative on break
We weren't modifying the lock set when intersecting with one coming
from a break-terminated block. This is inconsistent, since break isn't a
back edge, and it leads to false negatives with scoped locks. We usually
don't warn for those when joining locksets aren't the same, we just
silently remove locks that are not in the intersection. But not warning
and not removing them isn't right.

Aaron Puchert 530e074faa Thread safety analysis: Replace flags in FactEntry by SourceKind (NFC)
The motivation here is to make it available in the base class whether a
fact is managed or not. That would have meant three flags on the base
class, so I had a look whether we really have 8 possible combinations.

It turns out we don't: asserted and declared are obviously mutually
exclusive. Managed facts are only created when we acquire a capability
through a scoped capability. Adopting an asserted or declared lock will
not (in fact can not, because Facts are immutable) make them managed.

We probably don't want to allow adopting an asserted lock (because then
the function should probably have a release attribute, and then the
assertion is pointless), but we might at some point decide to replace a
declared fact on adoption.

Martin Probst b2780cd744 clang-format: [JS] handle "off" in imports
Previously, the JavaScript import sorter would ignore `// clang-format
off` and `on` comments. This change fixes that. It tracks whether
formatting is enabled for a stretch of imports, and then only sorts and
merges the imports where formatting is enabled, in individual chunks.

This means that there's no meaningful total order when module references are mixed
with blocks that have formatting disabled. The alternative approach
would have been to sort all imports that have formatting enabled in one
group. However that raises the question where to insert the
formatting-off block, which can also impact symbol visibility (in
particular for exports). In practice, sorting in chunks probably isn't a
big problem.

This change also simplifies the general algorithm: instead of tracking
indices separately and sorting them, it just sorts the vector of module
references. And instead of attempting to do fine grained tracking of
whether the code changed order, it just prints out the module references
text, and compares that to the previous text. Given that source files
typically have dozens, but not even hundreds of imports, the performance
impact seems negligible.

Currently, it uses `Standard: C++03` setting for clang-format, but this breaks e.g. u8"string" literals.
Also, angle brackets are the only place where C++03-specific formatting needs to be applied.

Denys Petrov b30521c28a [analyzer] Wrong type cast occurs during pointer dereferencing after type punning
Summary: During pointer dereferencing CastRetrievedVal uses wrong type from the Store after type punning. Namely, the pointer casts to another type and then assigns with a value of one more another type. It produces NonLoc value when Loc is expected.

Petr Hosek ea12d779bc [libc++] Support per-target __config_site in per-target runtime build
When using the per-target runtime build, it may be desirable to have
different __config_site headers for each target where all targets cannot
share a single configuration.

The layout used for libc++ headers after this change is:

```
include/
  c++/
    v1/
      <libc++ headers except for __config_site>
  <target1>/
    c++/
      v1/
        __config_site
  <target2>/
    c++/
      v1/
        __config_site
  <other targets>
```

This is the most optimal layout since it avoids duplication, the only
headers that's per-target is __config_site, all other headers are
shared across targets. This also means that we no need two
-isystem flags: one for the target-agnostic headers and one for
the target specific headers.

Ryan Santhirarajan 0395f9e70b [ARM] Neon Polynomial vadd Intrinsic fix
The Neon vadd intrinsics were added to the ARMSIMD intrinsic map,
however due to being defined under an AArch64 guard in arm_neon.td,
were not previously useable on ARM. This change rectifies that.

It is important to note that poly128 is not valid on ARM, thus it was
extracted out of the original arm_neon.td definition and separated
for the sake of AArch64.

Nico Weber 671f0e2e18 [clang] Make libBasic not depend on MC
Reduces numbers of files built for clang-format from 575 to 449.

1. Don't use llvm::ExceptionHandling in LangOptions. This isn't

   Tweaks the changes made in:
   - https://reviews.llvm.org/D93215

2. Move section name validation code added (long ago) in commit 30ba67439 out
   of libBasic into Sema and base the check on the triple. This is a bit less
   OOP-y, but completely in line with what we do in many other places in Sema.

Valeriy Savchenko ab5823867c [analyzer] Find better description for tracked symbolic values
When searching for stores and creating corresponding notes, the
analyzer is more specific about the target region of the store
as opposed to the stored value.  While this description was tweaked
for constant and undefined values, it lacked in the most general
case of symbolic values.

This patch tries to find a memory region, where this value is stored,
to use it as a better alias for the value.

Valeriy Savchenko 61ae2db2d7 [analyzer] Adjust the reported variable name in retain count checker
When reporting leaks, we try to attach the leaking object to some
variable, so it's easier to understand.  Before the patch, we always
tried to use the first variable that stored the object in question.
This can get very confusing for the user, if that variable doesn't
contain that object at the moment of the actual leak.  In many cases,
the warning is dismissed as false positive and it is effectively a
false positive when we fail to properly explain the warning to the
user.

This patch addresses the bigest issue in cases like this.  Now we
check if the variable still contains the leaking symbolic object.
If not, we look for the last variable to actually hold it and use
that variable instead.

Allocation site is the key location for the leak checker.  It is a

Before this patch, we calculated and used it twice in bug report and
in bug report visitor.  Such duplication is not only harmful
performance-wise (not much, but still), but also design-wise.  Because
changing something about the end piece of the report should've been
repeated for description as well.

David Candler b8baa2a913 [ARM][AArch64] Require appropriate features for crypto algorithms
This patch changes the AArch32 crypto instructions (sha2 and aes) to
require the specific sha2 or aes features. These features have
already been implemented and can be controlled through the command
line, but do not have the expected result (i.e. `+noaes` will not
disable aes instructions). The crypto feature retains its existing
meaning of both sha2 and aes.

Several small changes are included due to the knock-on effect this has:

- The AArch32 driver has been modified to ensure sha2/aes is correctly
  set based on arch/cpu/fpu selection and feature ordering.
- Crypto extensions are permitted for AArch32 v8-R profile, but not
  enabled by default.
- ACLE feature macros have been updated with the fine grained crypto
  algorithms. These are also used by AArch64.
- Various tests updated due to the change in feature lists and macros.
