This looks good to me, but needs to be rebased on top
of vhost mem slot management refactoring by dgilbert

Hi Andrey,

I was not aware the DAP is accessed by upstream Linux...
You sure this isn't rather part of some bootloader built-in self-test?

Hi,
This series seems to have some coding style problems. See output below for

Changes since v1:
Patch 1:
* Use rsb/rsc for gt/le. Now we always use "rI" as a constraint,
so we never have to load immediates into registers by hand.
Patch 2:
* We can't use add_ofs in the while condition and cmp_ofs in the
reduction and converge; use cmp_ofs always. Fixes the spa
The code sequence we were generating was only good for unsigned
comparisons. For signed comparisions, use the sequence from gcc.
Fixes booting of ppc64 firmware, with a patch changing the code
sequence for ppc comparisons.

The x86 vector instruction set is extremely irregular. With newer
editions, Intel has filled in some of the blanks. However, we don't
get many 64-bit operations until SSE4.2, introduced in 2009.
The subsequent edition was for AVX1, introduced in 2011, which added
three-operand addressing, and ad

For ARM SVE with VQ=3, we want to be able to dup a scalar
into a v256, use that, and then perform a second operation
with the v256 punned to a v128.
Allow operands to a vector operation be wider than necessary
for the output.

We already have immediate shifts. Add addition, multiplication,
and logical operations with an immediate. Subtraction can thus
be done with negation of the constant.
