Progress: * UM-2 [QEMU upstream maintainership] + Noticed we didn't enforce the M-profile "low 2 bits of SP are always 0" rule, and wrote a patch to fix that + Found and fixed a handful of other corner-case M-profile bugs + Some minor docs improvements * QEMU-406 [QEMU support for MVE (M-profile Vector Extension; Helium)] + Implemented the last 4 instruction patterns (VCVT, VRINT), bringing us to Progress: 210/210 (100%) + Found and fixed a few bugs in already-implemented instructions + Started looking at how to make the MVE loads/stores correctly raise alignment faults for unaligned addresses (this runs into problems because QEMU doesn't currently have a good API for doing the load/store the way we want to do it and also handling alignment faults) + Remaining TODO list for this task: - alignment fault behaviour, if not too difficult - report MVE registers via the gdbstub (pending on the XML format being fixed by gdb upstream) - send out patches for code review
