SCEV: add samesign tests for exit-limit computation (#124304)
As the tests demonstrate, computeExitLimitFromICmp needs no additional
changes to compute exit limits from an icmp with samesign.

[LLD][COFF] Keep hasData true in NullChunk constructor (#124368)
`NullChunk` instances do write data, even if it's always zero. Setting
`hasData` to false causes `Writer::assignAddresses` to ignore them
when calculating `rawSize`. This typically isn't an issue, as null chunks
are usually positioned within a section, and later chunks adjust the
size accordingly.
However, on ARM64EC, the auxiliary IAT is placed at the end of the
`.rdata` section and terminates with a null chunk. As a result, `rawSize`
is never updated to account for it, and space for the null chunk is not
allocated. Consequently, when `NullChunk::writeTo` is called, it receives
an invalid pointer - either pointing to the next section or beyond the
allocated buffer.

[InstCombine] Drop Range attribute when simplifying 'fshl' based on demanded bits (#124429)
When simplifying operands based on demanded bits, the return value range
of llvm.fshl might change. Keeping the Range attribute might cause
llvm.fshl to generate a poison and lead to miscompile. Drop the Range
attribute similar to `dropPosonGeneratingFlags` elsewhere.

[VPlan] Support multi-exit loops in HCFG builder.
Update HCFG construction to support multi-exit loops. If there is no
unique exit block, map the middle block of the initial plan to the exit
block from the latch.
This further unifies HCFG construction and prepares for use to also
build an initial VPlan (VPlan0) for inner loops.
Effectively NFC as this isn't used on the default code path yet.

[clang] Migrate away from PointerUnion::dyn_cast (NFC) (#124425)
Note that PointerUnion::dyn_cast has been soft deprecated in
PointerUnion.h:
// FIXME: Replace the uses of is(), get() and dyn_cast() with
// isa<T>, cast<T> and the llvm::dyn_cast<T>
This patch migrates uses of PointerUnion::dyn_cast to
dyn_cast_if_present (see the definition of PointerUnion::dyn_cast).
Note that we cannot use dyn_cast in any of the migrations in this
patch; placing
assert(!X.isNull());
just before any of dyn_cast_if_present in this patch triggers some
failure in check-clang.

[AArch64] Fix movk parsing with an .equ operand (#124428)
Prior to 5da801386c2b820a4596fc6d8da6b5f4a6da94b4, this code worked:
.equ p4_low_b0, 0x0000
movk x1, p4_low_b0, lsl 16
(The code above is from the isa-l project - I discovered this issue
while trying to compile it with clang 19 on MacOS on aarch64)
That commit fixed a different bug, but accidentally broke the case where
the second operand to movk is not a literal.
In 442f066fc464e953b7783230e95ccf2a67ebfb38, a fix was applied to handle
the case where the second operand is a value like "(Val) >> 16".
However, that didn't appear to fix the test case in this commit. In this
commit, we extend the change to handle the case where the second operand
is a identifier defined by .equ.
Fixes #124427

[Sema] Migrate away from PointerUnion::dyn_cast (NFC) (#124447)
Note that PointerUnion::dyn_cast has been soft deprecated in
PointerUnion.h:
// FIXME: Replace the uses of is(), get() and dyn_cast() with
// isa<T>, cast<T> and the llvm::dyn_cast<T>
Literal migration would result in dyn_cast_if_present (see the
definition of PointerUnion::dyn_cast), but this patch uses dyn_cast
because we expect AnyFunc to be nonnull.

[Clang] Add predefined macros for integer constants (#123514)
This adds predefined macros for integer constants to implement section 7.18.4 of ISO/IEC 9899:1999 in `<stdint.h>` in a safe way:
```
__INT8_C(c)
__INT16_C(c)
__INT32_C(c)
__INT64_C(c)
__INTMAX_C(c)
__UINT8_C(c)
__UINT16_C(c)
__UINT32_C(c)
__UINT64_C(c)
__UINTMAX_C(c)
```
Which improves compatibility with GCC and makes it trivial to implement
section 7.18.4 of ISO/IEC 9899:1999.
Clang defines `__INT<N>_C_SUFFIX__`, `__UINT<N>_C_SUFFIX__`,
`__INTAX_C_SUFFIX__` and `__UINTMAX_C_SUFFIX__`, but these macros are
useless for this purpose.
Let's say, for example, that `__INT64_C_SUFFIX__` expands to `L` or
`LL`. If the user defines them as a macros, the compiler will produce
errors if `INT64_C` is implemented in `<stdint.h>` using
`__INT64_C_SUFFIX__`:
**minimal-test.c:**
```cpp
#if defined(__clang__) & !defined(__INT64_C)

[msan] Add handlers for AVX masked load/store intrinsics (#123857)
This patch adds explicit support for AVX masked load/store intrinsics,
largely by applying the intrinsics to the shadows (but subtly different
to handleIntrinsicByApplyingToShadow()).
We do not reuse the handleMaskedLoad/Store functions. The key challenge
is that the LLVM masked intrinsics require a vector of booleans, while
AVX masked intrinsics use the MSBs of a vector of integers.
X86InstCombineIntrinsic.cpp::simplifyX86MaskedLoad mentions that the x86
backend does not know how to efficiently convert from a vector of
booleans back into the AVX mask format; therefore, they (and we) do not
reduce AVX masked intrinsics into LLVM masked intrinsics.

[msan] Add avx512-intrinsics.ll and avx512-intrinsics-upgrade.ll test case (#123980)
These are forked from the corresponding files in llvm/test/CodeGen/X86/.
avx512-intrinsics.ll shows that many intrinsics are already
heuristically handled by MSan, and can be used to track refinements to
the intrinsic handling.
avx512-intrinsics-upgrade.ll tests intrinsics that LLVM "auto-upgrades";
for example, @llvm.x86.avx512.mask.store is converted into
@llvm.masked.store (which has the interesting side effect that
MemorySanitizer can already handle it via its existing
handleMaskedStore).

[ELF] Make isExported accurate early
LTO compilation might define symbols not in the symbol table (e.g.
__emutls_v.x in test/ELF/lto/wrap-unreferenced-before-codegen.test).
These symbols have a false `isExported` until
`demoteSymbolsAndComputeIsPreemptible`. This is usually benign as we do
not reference `isExported` that early.
Ensure that `isExported` is correct early. This helps remove a redundant
`isExported` computation in `demoteSymbolsAndComputeIsPreemptible`.

[AArch64] Generate zeroing forms of certain SVE2.2 instructions (8/11) (#116834)
SVE2.2 introduces instructions with predicated forms with zeroing of
the inactive lanes. This allows in some cases to save a `movprfx` or
a `mov` instruction when emitting code for `_x` or `_z` variants of
intrinsics.
This patch adds support for emitting the zeroing forms of certain
`FRINTx`, `FRECPX`, and `FSQRT` instructions.

special cases for these types when using `__builtin_shufflevector`
or bitcast (using C-style cast operator) between vectors, both
extensively used in the generated code in `arm_neon.h`.

isDereferenceableAndAlignedInLoop. This was exposed by
the unit test IsDerefReadOnlyLoop in
unittests/Analysis/LoadsTest.cpp. I fixed this by falling
back on getConstantMaxBackedgeTakenCount if Predicates is
null - see line 316 in llvm/lib/Analysis/Loads.cpp. There
are no other changes.

[AArch64] Generate zeroing forms of certain SVE2.2 instructions (7/11) (#116833)
SVE2.2 introduces instructions with predicated forms with zeroing of
the inactive lanes. This allows in some cases to save a `movprfx` or
a `mov` instruction when emitting code for `_x` or `_z` variants of
intrinsics.
This patch adds support for emitting the zeroing forms of certain
`FLOGB` instructions.

[lldb][AArch64] Fix expression evaluation with Guarded Control Stacks (#123918)
When the Guarded Control Stack (GCS) is enabled, returns cause the
processor to validate that the address at the location pointed to by
gcspr_el0 matches the one in the link register.
```
ret (lr=A) << pc
| GCS |
+=====+
| A |
| B | << gcspr_el0
Fault: tried to return to A when you should have returned to B.
```
Therefore when an expression wrapper function tries to return to the
expression return address (usually `_start` if there is a libc), it
would fault.
```
ret (lr=_start) << pc
| GCS |
+============+
| user_func1 |
| user_func2 | << gcspr_el0
Fault: tried to return to _start when you should have returned to user_func2.
```
To fix this we must push that return address to the GCS in
PrepareTrivialCall. This value is then consumed by the final return and
the expression completes as expected.
If for some reason that fails, we will manually restore the value of
gcspr_el0, because it turns out that PrepareTrivialCall
does not restore registers if it fails at all. So for now I am handling
gcspr_el0 specifically, but I have filed
https://github.com/llvm/llvm-project/issues/124269 to address the
general problem.
(the other things PrepareTrivialCall does are exceedingly likely to not
fail, so we have never noticed this)
```
ret (lr=_start) << pc
| GCS |
+============+
| user_func1 |
| user_func2 |
| _start | << gcspr_el0
No fault, we return to _start as normal.
```
The gcspr_el0 register will be restored after expression evaluation so
that the program can continue correctly.
However, due to restrictions in the Linux GCS ABI, we will not restore
the enable bit of gcs_features_enabled. Re-enabling GCS via ptrace is
not supported because it requires memory to be allocated by the kernel.
We could disable GCS if the expression enabled GCS, however this would
use up that state transition that the program might later rely on. And
generally it is cleaner to ignore the enable bit, rather than one state
transition of it.
We will also not restore the GCS entry that was overwritten with the
expression's return address. On the grounds that:
* This entry will never be used by the program. If the program branches,
the entry will be overwritten. If the program returns, gcspr_el0 will
point to the entry before the expression return address and that entry
will instead be validated.
* Any expression that calls functions will overwrite even more entries,
so the user needs to be aware of that anyway if they want to preserve
the contents of the GCS for inspection.
* An expression could leave the program in a state where restoring the
value makes the situation worse. Especially if we ever support this in
bare metal debugging.
I will later document all this on
https://lldb.llvm.org/use/aarch64-linux.html.
Tests have been added for:
* A function call that does not interact with GCS.
* A call that does, and disables it (we do not re-enable it).
* A call that does, and enables it (we do not disable it again).
* Failure to push an entry to the GCS stack.

[libclc] Optimize CLC vector relational builtins (#124537)
Clang knows how to perform relational operations on OpenCL vectors, so
we don't need to use the Clang builtins. The builtins we were using
didn't support vector types, so we were previously scalarizing.
This commit generates the same LLVM fcmp operations as before, just
without the scalarization.

Extends rewriting of `loop` directives by supporting `bind` clause for
standalone directives. This follows both the spec and the current state
of clang as follows:
* No `bind` or `bind(thread)`: the `loop` is rewritten to `simd`.
* `bind(parallel)`: the `loop` is rewritten to `do`.
* `bind(teams)`: the `loop` is rewritten to `distribute`.

LAA: handle 0 return from getPtrStride correctly (#124539)
getPtrStride returns 0 when the PtrScev is loop-invariant, and this is
not an erroneous value: it returns std::nullopt to communicate that it
was not able to find a valid pointer stride. In analyzeLoop, we call
getPtrStride with a value_or(0) conflating the zero return value with
std::nullopt. Fix this, handling loop-invariant loads correctly.
