  PATCH v1: <https://sourceware.org/pipermail/binutils/2022-July/121691.html>
PATCH v2: <https://sourceware.org/pipermail/binutils/2022-October/123707.html>

Only change between v2 and v3 is a rebase to resolve conflict with commit
a8d181c0fdae ("RISC-V: xtheadfmemidx: Use fp register in mnemonics").

So, this is pretty much unchanged from v2.  As a reminder, this e-mail is
followed by the same cover letter as v2.

=============


Hello,

This patchset contains various tidying of RISC-V opcodes that would...

(a) Make coding style more consistent and/or more readable
(b) Remove unused constants
(c) Make new instruction names primary (clean old names except aliases)
(d) Make opcode entries functionally consistent.

I call this "batch 1" and deals with the most obvious (yet small and
various) issues.


[Overview of this Patchset]

PATCH 1/8: (a) Tidying (add space at the tail of pinfo)
PATCH 2/8: (a) Tidying (fix obvious misalignments on 'Zbb'/'Zba')
PATCH 3/8: (a) Tidying (remove spaces around "|" operator)
PATCH 4/8: (b) Remove unused instruction macros
PATCH 5/8: (c) SCALL -> ECALL, SBREAK -> EBREAK        (RISC-V ISA v2.1)
PATCH 6/8: (c) FMV.S.X -> FMV.W.X, FMV.X.S -> FMV.X.W  (RISC-V ISA v2.2)
PATCH 7/8: (c) Make old instruction names aliases
PATCH 8/8: (d) Use defined (and named) constants for instruction defining


Thanks,
Tsukasa
