Comment (by kencu):

 in TigerPorts you will find fixes for up to clang-7.0 to run on Tiger
 Intel. It works fairly well, still some assembler quirks on 10.4 I recall.

 I forget now how far I got with TigerPPC… clang-3.8 I think, that supports
 thread_local.

 I fixed Leopard up to clang-9.0 on Intel, and clang-7.0 on PPC.

 clang/llvm generates useless broken code on PPC anyway, however, even if
 it does work.
