[Qemu-devel] [PATCH v2 00/22] target-mips: add MIPS64R6 Instruction Set


From: Leon Alrae
Subject: [Qemu-devel] [PATCH v2 00/22] target-mips: add MIPS64R6 Instruction Set support
Date: Wed, 11 Jun 2014 16:19:30 +0100

The following patchset implements MIPS64 Release 6 Instruction Set.
New instructions are added and also there is a number of instructions which
are deleted or moved (the encodings have changed).

The MIPS64 Release 6 documentation is available:
http://www.imgtec.com/mips/architectures/mips64.asp

The following patch series is focusing on instruction set changes only.
There is also a new generic cpu supporting R6.

Please note that even though the new Floating Point instructions were added,
softfloat for MIPS has not been updated yet (in R6 MIPS FPU is updated to
IEEE2008). Also, current patchset does not include MIPS64 Privileged Resource
Architecture modifications. All those changes will follow the current patchset
soon.

v2:
* addressed all comments so far from Richard and Aurelien. More detailed
  changelog included in the separate patches.
* added missing zero register case for LSA, ALIGN and BITSWAP instructions

Leon Alrae (18):
  target-mips: define ISA_MIPS64R6
  target-mips: signal RI Exception on instructions removed in R6
  target-mips: add SELEQZ and SELNEZ instructions
  target-mips: move LL and SC instructions
  target-mips: extract decode_opc_special* from decode_opc
  target-mips: split decode_opc_special* into *_r6 and *_legacy
  target-mips: signal RI Exception on DSP and Loongson instructions
  target-mips: move PREF, CACHE, LLD and SCD instructions
  target-mips: redefine Integer Multiply and Divide instructions
  target-mips: move CLO, DCLO, CLZ, DCLZ, SDBBP and free special2 in R6
  target-mips: Status.UX/SX/KX enable 32-bit address wrapping
  target-mips: add Addressing and PC-relative instructions
  softfloat: add functions corresponding to IEEE-2008 min/maxNumMag
  target-mips: add new Floating Point instructions
  target-mips: do not allow Status.FR=0 mode in 64-bit FPU
  mips_malta: update malta's pseudo-bootloader - replace JR with JALR
  target-mips: use pointers referring to appropriate decoding function
  target-mips: define a new generic CPU supporting MIPS64R6

Yongbok Kim (4):
