Hello all, this patch checks in mdcompact, the tool written in elisp that I used to mass convert all the multi choice pattern in the aarch64 back-end to the new compact syntax. I tested it on Emacs 29 (might run on older versions as well not sure), also I verified it runs cleanly on a few other back-ends (arm, loongarch). The tool can be used to convert a single pattern, an open buffer or all md files in a directory. The tool might need further adjustment to run on some specific back-end, in case very happy to help. This patch was pre-approved here [1].
