Some headers in /usr/include/llvm are gone:

CodeGen/WasmAddressSpaces.h
CodeGen/StableHashing.h
DebugInfo/PDB/Native/Formatters.h
DWARFLinker/DWARFLinkerCompileUnit.h
DWARFLinker/DWARFStreamer.h
DWARFLinker/DWARFLinker.h
DWARFLinker/DWARFLinkerDeclContext.h
DWARFLinkerParallel/StringPool.h
DWARFLinkerParallel/AddressesMap.h
DWARFLinkerParallel/DWARFLinker.h
DWARFLinkerParallel/StringTable.h
DWARFLinkerParallel/DWARFFile.h
ExecutionEngine/Orc/DebuggerSupportPlugin.h
Support/Host.h
Transforms/Vectorize.h

hope the removal won't break downstream packages...

Rustc needs to be adapted: ​https://github.com/rust-lang/rust/pull/116672

The relevant part can be done via a sed: sed -i 's/f[0-9][0-9]:/i128:128-&/' compiler/rustc_target/src/spec/targets/{i?86,x86_64}*.rs

Not enough, another sed: sed -r '/static_assert_size!\((Lit|MetaItemLit|BasicBlockData|Terminator)/d' -i compiler/{rustc_ast/src/ast.rs,rustc_middle/src/mir/mod.rs}
