[AArch64] Fix Windows prologue handling to pair more registers. (#170214)
Currently, there's code to suppress pairing, but we don't actually need
to suppress that; we just need to suppress the formation of
pre-decrement/post-increment instructions.
Pairing saves an instruction in some cases, and enables packed unwind in
some cases.
mxge(4): avoid clang 21 warning in NO-IP configuration
Building the LINT-NOIP kernel on amd64 with clang 21 results in a
-Werror warning similar to:
sys/dev/mxge/if_mxge.c:1846:44: error: variable 'sum' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
1846 | cksum_offset, sizeof(sum), (caddr_t)&sum);
| ^~~
Indeed, if both `INET` and `INET6` are undefined, `sum` is never
initialized. Initialize it to zero to silence the warning.

[lldb] Support both RISCV-32 and RISCV-64 in GetRegisterInfo (#176472)
`GetRegisterInfo` hardcodes to use `RegisterInfoPOSIX_riscv64` instead
of checking the triple to determine whether to use
`RegisterInfoPOSIX_riscv64` or `RegisterInfoPOSIX_riscv32`.
Someone put up a [PR](https://github.com/llvm/llvm-project/pull/175262)
for this, but seems to have removed their account and the associated PR
with it.
Fixes #175092
CMake cache file for building Pico SDK toolchain (#113267)
This cache file demonstrates how to build a complete baremetal
Clang/LLVM toolchain that can be used to build the Pico SDK.
tdestroy: don't visit one-child node twice
Change tdestroy() to immediately free a node with no right child as
soon as it is encountered. Currently, such nodes are visited twice
before deletion.

[lldb] Fix llvm_unreachable for invalid Wasm address (#176464)
We had an llvm_unreachable following a switch on the WasmAddress's type.
However, the type is encoded in a larger 64 bit address, and therefore
it's possible to create an invalid value that doesn't map back on one of
the enum types.
We could try to diagnose that in the wrapper, or treat all invalid types
the same. I took the latter approach because it makes it easier to show
the invalid type after the fact in an error message.
