Subject: [Qemu-devel] [PATCH 00/38] tcg vector improvements
Date: Fri, 19 Apr 2019 21:34:04 -1000	[thread overview]
Message-ID: <20190420073442.7488-1-richard.henderson@linaro.org> (raw)

Based-on: tcg-next, which at present is only tcg_gen_extract2.

The dupm patches have been on list before, with a larger context
of supporting tcg/ppc.  The rest of the set was written to support
David's s390 vector patches.  In particular:

(1) Add vector absolute value.
(2) Add vector shift by non-constant scalar.
(3) Add vector shift by vector.
(4) Add vector select.
(5) Be more precise in handling target-specific vector expansions.

And then there's a set of bugs that I encountered while working
on this across x86, aa64, and ppc hosts.  Tested primarily with
aa64 as the guest, via RISU.
