2023-06-28target/sparc: Use tcg_gen_lookup_and_goto_ptr for v9 WRASIRichard Henderson
We incorporate %asi into tb->flags so that we may generate inline code for the many ASIs for which it is easy to do so. Setting %asi is common for e.g. memcpy and memset performing block copy and clear, so it is worth noticing this case. We must end the TB but do not need to return to the main loop.
