+- 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.
