I'll be posting the following nine parts: 1: top-level config.sub 2: reload: reloads_unique_chain_p() 3: reload: reload_reg_free() 4: reload: push_reload() and reload_inner_reg_of_subreg() 5: Misc config stuff and config/ia16 6: docs 7: backends.html 8: testsuite fixes 9: testsuite skip/xfail The back end expects code, data and stack to exist in a single 64 kB segment and hardware floating point is not implemented. Test results are at . I have more testsuite patches coming, so the results will improve. The simulator setup is also rather crude at the moment and I'll post a folloup to this message in the next few days with more details once I tie a few loose ends. -- Rask Ingemann Lambertsen
