- Update to version 18.1.6.
* Fixes issues where LLVM is either generating the incorrect thunk
for a function with aligned parameters or didn't correctly pass
through the return value when StructRet was used.
* `-Xclang -target-feature -Xclang +unaligned-scalar-mem` can be
used to enable unaligned scalar memory accesses for CPUs that
do not support unaligned vector accesses. `-mno-strict-align`
will enable unaligned scalar and vector memory accesses.
* Don't replace an aliasee with an alias that has weak linkage.
This avoids incorrect linkage that can lead to using the wrong
symbols during linking time.
* Fixes build failures when compiling AVX512 code using
`-march=native` on machines without AVX512. The problem was
introduced in LLVM 18.1.5.
* Fixes crash in AArch64 backend when having `true` or `false` as
operand for `fcmp` instruction on IR level.
* Fixes compiler crash when user specifies `-mno-evex512` with
AVX512 features but no AVX512VL.
* Fixes a bug that tries to do VBROADCAST_LOAD for `f16` without
AVX2.
- Rebase llvm-do-not-install-static-libraries.patch.
