Squashed commit of the following: commit44a6544242Author: Kelvin Sherlock <ksherlock@gmail.com> Date: Wed Aug 11 22:10:11 2021 -0400 improved 32-bit (well, smartport is 24-bit) block support commit7fc041289fAuthor: Kelvin Sherlock <ksherlock@gmail.com> Date: Wed Aug 4 23:49:15 2021 -0400 convert the extent blocks into 32-bit absolute blocks when loading. Currently the block comparisons are still 16-bit, though. commit0fabe65acaAuthor: Kelvin Sherlock <ksherlock@gmail.com> Date: Tue Aug 3 20:13:27 2021 -0400 move stack adjustment code to take effect from the callback routines commit6da1f9fa3cAuthor: Kelvin Sherlock <ksherlock@gmail.com> Date: Tue Jul 27 21:31:23 2021 -0400 re-arrange to avoid relative expression warning commitdbfe66cc99Author: Kelvin Sherlock <ksherlock@gmail.com> Date: Tue Jul 27 21:31:01 2021 -0400 use smartport.aii commit95aa4d8bd5Author: Kelvin Sherlock <ksherlock@gmail.com> Date: Thu Jul 22 23:58:20 2021 -0400 large volume support (WIP, untested). the general theory is, multiply the extents by the allocation adjustment to get physical block offsets. currently, comparisons are still 16-bit though.
