I just ran into this issue while looking at libadwaita-1. I'm not 100% sure yet what would need to be done to enable full JIT support on sparc64. I assume that the missing component is liborc, isn't it? Looking at the LLVM upstream sources, I see no obvious reason why liborc should not be supported on sparc64. But I'm not an expert on liborc, so I might be missing something. Adrian -- .''`.
