My GitHub tree now has fixes for the above as well as all pending A64
pull requests. The commits are:
34bbde5 * target-arm: A64: add remaining CLS/Z vector ops
96d890c * target-arm: A64: add FSQRT to C3.6.17 (two misc)
997e712 * target-arm: A64: fix bug in add_sub_ext an handling rn
c37ba93 * target-arm: A64: Add last AdvSIMD Integer to FP ops
1e35ff3 * target-arm: A64: Implement AdvSIMD reciprocal ops
46ec7d9 * peter/a64-working target-arm: A64: Implement PMULL instruction
