Could possibly you check whether this happens for abi_x86_64 as well?
(In reply to Marek Szuba from comment #3) > Could possibly you check whether this happens for abi_x86_64 as well? I'm running into the same problem. The package installs correctly with -abi_x86_32 and just abi_x86_64.
This matches my own observations. The problem is not with a missing rule, llvm-tblgen is an executable provided by sys-devel/llvm - except for some reason upstream sets this using set() rather than find_executable(). Interesting that this problem only occurs with llvm-10, I've just double-checked and opencl-clang:9 builds find with ABI_X86: 32.

This works fine for 32-bit builds of SLOT=8 and 9 as well as 64-bit builds of all three slots, however 32-bit builds of SLOT=10 fail due to having been unable to locate the executable in question. Whatever the reason for this is, actually looking for llvm-tblgen with find_program() solves the issue, at least on my system anyway.
