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): target-mips: add ALIGN, DALIGN, BITSWAP and DBITSWAP instructions target-mips: add Compact Branches target-mips: add new Floating Point Comparison instructions target-mips: remove JR, BLTZAL, BGEZAL and add NAL, BAL instructions disas/mips.c | 211 +++- fpu/softfloat.c | 37 +- hw/mips/mips_malta.c | 10 +- include/fpu/softfloat.h | 4 + target-mips/cpu.h | 23 +- target-mips/helper.h | 53 + target-mips/mips-defs.h | 28 +- target-mips/op_helper.c | 243 +++ target-mips/translate.c | 3833 +++++++++++++++++++++++++++++++----------- target-mips/translate_init.c | 29 + 10 files changed, 3459 insertions(+), 1012 deletions(-) -- 1.7.5.4
