[PATCH v2 00/15] target/arm: partial vector cleanup

[Richard Henderson]

This is not complete, but shows the direction I'd like to go.

It may well help what Peter is doing with the neon decodetree
conversion.  It may be helpful to apply before the conversion
in order to reduce the number of special cases.  As may
continuing with the cleanup; I'll probably work on that more
next week.

Version 2 extracts more bits from my sve2 branch.  There's
still more to pull back, especially for crypto_helper.c, where
there are also tail clearing bugs to fix.
