[Qemu-devel] [PATCH v2 00/25] A64: Neon patches, sixth set

[Peter Maydell]

Hi. This is a second version of the A64 Neon patchset six
which I sent out a little while back. Changes:
 * fixed the 'hunk in wrong patch' snafu
 * adjusted FCVTN to pass 'size - 1' to handle_2misc_narrow;
   this puts it in line with other callers and means the
   function always takes the size of destination element
 * added more patches on the end, implementing
   + SQSHL, SQSHLU, UQSHL
   + FCVTZS, FCVTZU
   + URECPE, FRECPE
   + SQXTN, SQXTUN, UQXTN in s2misc
   + FCVTXN
   + URSQRTE, FRSQRTE

This means the only unimplemented instructions are:
SUQADD, USQADD, SQABS, SQNEG. (We're working on those but
they didn't quite make it and I wanted to send this
series out today.)

NOTE: I intend to get these patches in for rc1, so will
be putting them into a pull request in time for the 19th
(Wednesday) in the absence of review issues.

The (trivial) softfloat patch is provided under the
softfloat 2a or 2b license at your option.

thanks
