I was hoping these added lines would enable the conversion functions, but it

clang -target s390x-linux-gnu -march=z16 ./test.c -O3 -o ./a.out
--rtlib=compiler-rt
/usr/bin/ld: cannot find
/home/ijonpan/llvm-project/build/lib/clang/20/lib/s390x-unknown-linux-gnu/libclang_rt.builtins.a:
No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```
There is something like COMPILER_RT_HAS_${arch}_FLOAT16 in
compiler-rt/lib/builtins/CMakeLists.txt, but I can't find anyplace to add s390x
to the targets that will build libclang_rt.builtins.a.
I have configured with -DLLVM_ENABLE_PROJECTS="clang;compiler-rt"
Would anyone know off-hand how to make this work? Thanks.
