[Qemu-devel] [PATCH for-2.0 v2 0/2] A64: Implement last four Neon insns

[Peter Maydell]

These two patches implement the last four A64 Neon instructions:
 SQNEG, SQABS, USQADD, SUQADD

meaning that we have complete coverage of the userspace instruction
set, with the exception of the optional crypto and CRC instructions.

As with the previous set, these are safe changes so I'm planning to
get them into 2.0 even though they're not strictly speaking
bugfixes. (Specifically, expect to see these plus a few other
bugfixes in a pullreq tomorrow aiming at rc1.)

Changes v1->v2: use extract32/deposit32 in the USATACC and
SSATACC macros rather than raw bit-twiddling.

thanks
