[CodeGen] Use unique_ptr for FunctionInfo to prevent memory leaks (#196603)
Raw pointer return from `FunctionInfo::create` caused leaks in callers
like `computeABIInfoUsingLib`, breaking BPF tests on ASan bots.
Using `std::unique_ptr` enforces automatic cleanup.
Fixes leak from #194460.

[mlir][tensor] Enhance pattern to fold extract_slice(insert_slice) (#195045)
Extend the DropRedundantRankExpansionOnExtractSliceOfInsertSlice pattern
to support cases where the expanded dimensions are a subset of the
dropped dimensions, rather than requiring them to be exactly equal.
For example:
```
%inserted_slice = tensor.insert_slice %src into %dest[0, 0, 0, 0] [1, 1, 128, 480] [1, 1, 1, 1] :
tensor<128x480xf32> into tensor<1x1x128x480xf32>
%extracted_slice = tensor.extract_slice %inserted_slice[0, 0, 0, 0] [1, 1, 123, 1] [1, 1, 1, 1] :
tensor<1x1x128x480xf32> to tensor<123xf32>
```
can be folded into:
```
%extracted_slice = tensor.extract_slice %src[0, 0] [123, 1] [1, 1] :
tensor<128x480xf32> to tensor<123xf32>
```
Revert "[BOLT] Fix EH data encoding checks in relocateEHFrameSection (#195691)" (#196672)
This reverts commit 7ab26d7c3a160e1dc166f2673644baa396703ee5.
There is test failure in bolt-tests::exceptions-split-strip.test.
detect out of bound reads from an int overflow in the bpf_mem backends.
frank denis reported a problem in bpf_mem_ldw where a large indirect
load offset could have the end of buffer calculation land at UINT_MAX
and wrap, allowing a read of memory outside the buffer.
this change tweaks the buffer checks by checking if the load offset
is in range, taking that away from the buffer length, and then
checking if the size of the load is in the remaining buffer length.
this is the pattern that the bpf_mbuf_ops backend uses.
this problem also exists in bpf_mem_ldh, so this code is factored
out and used in all the bpf_mem_ops load backends.
note that this issue is specific to the bpf_mem_ops backend used
for running bpf filters against a vanilla memory buffer. this backend
is largely unused in the kernel, which almost always uses the
bpf_mbuf_ops backend to run filters against network packets in
mbufs. the bpf_mem_ops are only used by ppp(4) for the "active-filter"

Add basic NFSv4 change-attribute regression tests
This commit adds a variety of tests in which we validate
the behavior the the NFSv4 change-attribute FATTR4_CHANGE over
a variety of NFS operations that should advance it.
[RISCV] Use the nhs.lea.h/w/d instead of nhs.lea.h/w/d.ze with Sh1AddPat. (#196660)
The srliw already took care of zeroing the upper bits. Using the non-.ze
form is consistent with the Zba version of this pattern.
[clang][deps] Move `ScanningOutputFormat` out of the library (#196631)
Basing behavior of the dependency scanner on the final output format is
a leaky abstraction. Instead, we should aim to introduce proper feature
flags.

[BOLT][NFCI] Consolidate DataReader::setEntryCounts (#196411)
FuncBranchData/BinaryFunction exec/external entry counts are set
in multiple places in `DataReader`:
- FBD: in `parse` and `appendFrom`,
- BF: in `preprocessProfile` and `matchProfileData`.
Consolidate to `setEntryCounts` called from `readProfile`.
Drop explicit counters, compute them from `FBD::EntryData`.

[lldb] Handle SIGINT via the MainLoop signal thread (on POSIX) (#195959)
The driver's async SIGINT handler called
SBDebugger::DispatchInputInterrupt directly. That is not
async-signal-safe and can lead to a crash.
Register SIGINT with the existing signal-thread MainLoop instead so
DispatchInputInterrupt runs in normal thread context. The Windows path
is unchanged and keeps the legacy async handler.
While DispatchInputInterrupt runs, the callback temporarily installs
SIG_DFL so a second Ctrl-C still hard-terminates the process, preserving
the escape hatch users rely on when the debugger is unresponsive.
Moving SIGINT off the main thread means a Ctrl-C no longer interrupts
blocking syscalls there (e.g. a Python REPL waiting on input or
sleeping), so Python never observes the queued interrupt and
KeyboardInterrupt is not raised. To restore that behavior, after
dispatching the interrupt the callback re-raises SIGINT on the main

[mlir][AMDGPU] Add, unify verification of memref index counts (#196657)
This PR verifies that, on operations that have
`%memref[%idx0, %idx1, ...]` arguments, the number of indices matches
the rank of the memref being passed in.
While we're here, fixes capitalization for certain verification error
messages.

[flang][cuda] Widen stream argument to i64 in stream intrinsic lowering (#196650)
`genCUDASetDefaultStream` and `genCUDAStreamDestroy` build their runtime
call with an `i64` stream parameter but pass the actual argument
straight through, so a smaller-kind actual (e.g. the literal `0` in
`cudaforSetDefaultStream(0)`) produces an ill-typed `fir.call`:
```
error: 'llvm.call' op operand type mismatch for operand 0: 'i32' != 'i64'
```
Insert a `fir.convert` to `i64` before the call, matching what
`genCUDASetDefaultStreamArray` already does.
[lld][WebAssembly] Remove the experimental warning for PIC/dynamic linking (#196566)
The current dynamic linking support has been used for several years not
both in emscripten and in wasi-sdk and is documented
https://github.com/WebAssembly/tool-conventions/blob/main/DynamicLinking.md.
We did/do have have plans to develop another version of the dynamic
linking ABI that doesn't use a global symbol namespace, and that can
still happen, but the current API is clearly production worthy
regardless of future plans.
This change removes the linker warning and the corresponding
`--experimental-pic` flag.
If we do want to still make breaking changes to the dylink format we can
rename the `dylink.1` section (which already contains a version number).
This change is leads the way for enabling shared libraries by default in
emscripten.
