The extending loads combine tries to prefer sign-extends folding into loads vs
zexts, and in cases where a G_ZEXTLOAD is first used by a G_ZEXT, and then used
by a G_SEXT, it would select the G_SEXT even though the load is already
zero-extending.
Fixes issue #59630
This reverts commit 5356fefc19df3fbf32d180b1b10e6226e8743541.
It looks like Polly still relies on the legacy SCCP pass. Bring it back
until the best way forward is determined.
This is part of the optimization pipeline, of which the legacy pass manager version is deprecated.

Allocation actions may run JIT'd code, which isn't permitted in -noexec mode.
Testcases that depend on actions running should be moved to the ORC runtime.
This caused false positives because the existing logic was not taking into account that pointers could have a tag in them.

This patch introduces a new type __externref_t that denotes a WebAssembly opaque
reference type. It also implements builtin __builtin_wasm_ref_null_extern(),
that returns a null value of __externref_t. This lays the ground work
for further builtins and reference types.

~TaskAsyncInfoWrapperTy() calls isDone. With synchronize inside isDone, we need to handle the error return from synchronize in the destructor.
The consumers of TaskAsyncInfoWrapperTy, targetDataMapper and targetKernel, both call AsyncInfo.synchronize() before exiting.
For this reason in ~TaskAsyncInfoWrapperTy(), calling synchronize() via isDone() is redundant.
This patch removes synchronize() call inside isDone() and makes it a lightweight check.
__tgt_target_nowait_query needs to call synchronize() before checking isDone().

Experimental support for the zfa extension was recently added in https://reviews.llvm.org/D141984. A couple of the normal test changes and clang plumbing got missed in that change. This commit updates the usual suspects.

Context: The `expression` command uses artificial variables to store the expression
result. This result variable is unconditionally kept around after the expression command
has completed. These variables are known as persistent results. These are the variables
`$0`, `$1`, etc, that are displayed when running `p` or `expression`.
This change allows users to control whether result variables are persisted, by
introducing a `--persistent-result` flag.
This change keeps the current default behavior, persistent results are created by
default. This change gives users the ability to opt-out by re-aliasing `p`. For example:
```
command unalias p
command alias p expression --persistent-result false --
```
For consistency, this flag is also adopted by `dwim-print`. Of note, if asked,
`dwim-print` will create a persistent result even for frame variables.

Currently the implementation of __VA_OPT__ will treat the concatenation of a
non-placemaker token and placemaker token as a placemaker token which is not
correct. This will fix the implementation and treat the result as a

Since binary ID lookup makes CLI object arguments optional, it should be
possible to pass a list of source files without a binary. Unfortunately,
the current syntax will always interpret the first source file as a
binary. This change adds a `-sources` option to cause all later
positional arguments to be considered sources.

previously only been supported for sign extension on byte, halfword,

This adds the infrastructure to use TH.EXT and TH.EXTU for arbitrary

In json::Value, getAsInteger returns an optional<int64_t> and getAsNumber
returns an optional<double>. If a value is larger than what an int64_t
can hold but smaller than what a uint64_t can hold, the getAsInteger
function will fail but the getAsNumber will succeed. However, the value
shouldn't be interpreted as a double.
