Subject: [Qemu-devel] [PATCH 00/23] target-m68k: prepare to introduce 680x0 instruction set
Date: Tue, 25 Oct 2016 16:49:58 +0200	[thread overview]
Message-ID: <1477407021-30755-1-git-send-email-laurent@vivier.eu> (raw)

As I'm not able to manage too large series,
this series is a subset of the series I sent in May:
https://lists.gnu.org/archive/html/qemu-devel/2016-05/msg00501.html

It doesn't introduce any new instructions but:
- introduce the new processors feature flags
- introduce new flags management as proposed by Richard

I've checked it doesn't break coldfire support:
http://wiki.qemu.org/download/coldfire-test-0.1.tar.bz2
but it can't boot a 680x0 processor kernel.

I've fixed some style issues reported by checkpatch.pl and merged
some of the patches cleaning up flags (as suggested by Richard).

John Paul Adrian Glaubitz (1):
  target-m68k: Build the opcode table only once to avoid multithreading
    issues

Laurent Vivier (13):
  target-m68k: fix DEBUG_DISPATCH
  target-m68k: define m680x0 CPUs and features
  target-m68k: manage scaled index
  target-m68k: introduce read_imXX() functions
  target-m68k: set disassembler mode to 680x0 or coldfire
  target-m68k: define operand sizes
  target-m68k: set PAGE_BITS to 12 for m68k
  target-m68k: REG() macro cleanup
  target-m68k: allow to update flags with operation on words and bytes
  target-m68k: remove m68k_cpu_exec_enter() and m68k_cpu_exec_exit()
  target-m68k: update move to/from ccr/sr
  target-m68k: don't update cc_dest in helpers
  target-m68k: update CPU flags management

Richard Henderson (9):
  target-m68k: Replace helper_xflag_lt with setcond
