This patchseries provides the third and fourth slices of the MVE
implementation, which gives us complete coverage of all instructions
and brings us to the point where we can actually enable it.
In this series:
* fixes for minor bugs in a couple of the insns already upstream
* all the remaining integer instructions
* the remaining loads and stores (scatter-gather and interleaving)
* the floating point instructions
* patch enabling MVE for the Cortex-M55
Things still to do:
* MVE loads/stores should check alignment (this will depend on
the patchset that RTH just sent out, and I didn't want to
entangle the two features unnecessarily)
* gdbstub support (blocked on the gdb folks nailing down what
the XML for it should be)
* optimization: many of the insns should have inline versions
to use when we know we aren't doing any predication
But none of those are blockers for this landing upstream once
we reopen for 6.2.
Still to review:
03, 07, 10, 21, 26, and the new patches 36-53
thanks
