[Qemu-devel] [PATCH 0/8] A64: Neon support, fourth set

[Peter Maydell]

This is the fourth set of A64 Neon support patches. This set
provides complete implementations of the categories:
 * scalar x indexed
 * vector x indexed
 * scalar three-different
and fills in all the previously missing instructions in:
 * vector 3-reg-same
 * scalar 3-reg-same

It includes adding support in softfloat for "fused multiply,
add and then divide by two", because the A64 VRECPS instruction
requires it.

By my reckoning the parts that are still missing for Neon are:
 * parts of scalar shift-immediate and vector shift-immediate
 * parts of scalar-2-misc
 * most of vector-3-diff
 * parts of vector-2-misc
