[SLP]Skip operands comparing on non-matching (but compatible) instructions
If the instructions are compatible but non-matching (zext-select pair as
example), no need to perform operands analysis, just return that they
are matching.
Fix SCRAM authentication bugs
1. Fix typo: auth_ctx.client_next_mech -> auth_ctx.next_mech
The AuthenticationContext dataclass only has next_mech, not
client_next_mech. This would cause AttributeError at runtime.
2. Set auth_ctx.auth_data when processing CLIENT_FIRST_MESSAGE
Without this, abandoning a SCRAM exchange causes TypeError
when check_auth_mechanism tries to access auth_data['user'].

[MLIR][Arith] FastMath extf conversion without NaN checks (#180926)
This PR allows the expand op converter to consider the NoNaN fastmath
attribute to disable the runtime checks for NaNs in E8M0 types. Default
behaviour is still the same.
The OCP document provides all-ones as NaN for E8M0, but for pre-MX I8
quantization, the checks for NaNs are prohibitively expensive,
especially if the hardware doesn't have native support for that type.
[Clang] Don't diagnose missing members when looking at the instantiating class template (#180725)
The perfect matching patch revealed another bug where recursive
instantiations could lead to the escape of SFINAE errors, as shown in
the issue.
Fixes https://github.com/llvm/llvm-project/issues/179118
[MLIR][Python] Make traits declarative in python-defined operations (#180748)
This will support two syntax in python-defined dialects.
First is that traits can now be declared in class parameters, e.g.
```python
class ParentIsIfTrait(DynamicOpTrait): #define a python-side trait
@staticmethod
def verify_invariants(op) -> bool:
if not isinstance(op.parent.opview, IfOp):
op.location.emit_error(
f"{op.name} should be put inside {IfOp.OPERATION_NAME}"
)
return False
return True
class YieldOp( # attach two traits: IsTerminatorTrait, ParentIsIfTrait
TestRegion.Operation, name="yield", traits=[IsTerminatorTrait, ParentIsIfTrait]
):

[AArch64][llvm] Improve codegen for FP_TO_*_SAT
Skip the SVE scalar-combine for saturating FP->INT when the scalar op
is legal, so we use simpler scalar codegen in streaming modes.
mvc: catch empty data in CSV import
Catch empty lines. A single "," will generate
an empty string instead of NULL so we are good
here. It's safe to assume we have at least one
property in the line, otherwise the data is
useless to us anyway.
From the fgetcsv() manual:
A blank line in a CSV file will be returned as an array
comprising a single null field, and will not be treated
as an error.
See: https://www.php.net/manual/en/function.fgetcsv.php
[mlir][tosa] Fix validation of `dim` op when reliant on datatype extension (#180915)
For example:
```
error: 'tosa.dim' op illegal: requires [bf16, shape] but not included in the profile compliance [shape]
%0 = tosa.dim %arg0 {axis = 4 : i32} : (tensor<4x5x8x8x6x4xbf16>) -> !tosa.shape<1>
```
Here dim requires support to be declared for the BF16 and SHAPE
extensions, but only SHAPE was specified in the op declaration.
[AArch64][llvm] Preserve FP_TO_*_SAT VT operand in SVE scalar-combine
Updated RUN lines and generated new `CHECK‑SME`/`CHECK‑SVE` lines in:
llvm/test/CodeGen/AArch64/arm64-cvt-simd-fptoi.ll
llvm/test/CodeGen/AArch64/arm64-cvtf-simd-itofp.ll
by adding `-force-streaming` and `-force-streaming-compatible` runs,
as pre-commit tests for a future change to enable FPRCVT streaming.
This triggers a SVE scalar-combine path which requires a code update.
FP_TO_*_SAT nodes require operand 1 (the saturation VT) to be present.
Without it the node is malformed and hits the SelectionDAG assertion
“Invalid child # of SDNode!”.
Also, skip the SVE combine if the scalar/custom op is already legal.

[LAA] Use SCEVPtrToAddr in tryToCreateDiffChecks. (#178861)
The checks created by LAA only compute a pointer difference and do not
need to capture provenance. Use SCEVPtrToAddr instead of SCEVPtrToInt
for computations.
To avoid regressions while parts of SCEV are migrated to use PtrToAddr
this adds logic to rewrite all PtrToInt to PtrToAddr if possible in the
created expressions. This is needed to avoid regressions.
Similarly, if in the original IR we have a PtrToInt, SCEVExpander tries
to re-use it if possible when expanding PtrToAddr.
Depends on https://github.com/llvm/llvm-project/pull/178727.

[libc++] Rewrite the std::pop_heap benchmark (#179911)
Testing a bunch of random types has relatively little value. This
reduces the number of benchmarks so we can run them on a regular basis.
This saves ~90 seconds when running the benchmarks.
