this bugreport tracks questions comments and feedback for v2 of ls012.
* DONE - add LD/ST-shifted table from ls004
* TODO - add a binutils column with whether added support or not
added LD/ST-Indexed-Shifted table to optable.csv, and add description
into group of instructions. whether a decision is made to include them
or not is entirely up to the ISA WG.
i've also added LDST-Shifted-Postinc (!) which is another 37
instructions (!) very deliberately to raise awareness of the
problem of opcode allocation, but also to solicit, under
"Due Diligence", a response from the ISA WG as to why they
should or should not be included.
i would expect the answer "eek!" but then that helps make
te case for shift-and-add as a much more palatable alternative.
added a new column "binutils"
indicates if the instruction has been added and/or needs updating.
Thank you for this table! I think with a small tuning I can re-use it to filter it for binutils.
