Current QEMU m68k emulation only supports ColdFire processors. This series adds compatibility with 680x0 processors.
Only non-privileged instruction are implemented. 680x0 FPU instructions are not implemented. Once this series included in the QEMU mainline I will send a new series with FPU instructions. With it, we can start a debian etch-m68k container (init and all the bazaar). Laurent Vivier (30): m68k: define m680x0 CPUs and features m68k: manage scaled index m68k: introduce read_imXX() functions m68k: set disassembler mode to 680x0 or coldfire m68k: define operand sizes m68k: REG() macro cleanup m68k: allow to update flags with operation on words and bytes m68k: update CPU flags management m68k: add X flag helpers m68k: tst bugfix m68k: improve clr/moveq m68k: Manage divw overflow m68k: set Z and N on divu/muls overflow as a real 68040 m68k: allow adda/suba to add/sub word m68k: add more modes to movem m68k: Add all access modes and data sizes to some 680x0 instructions m68k: ori/andi/subi/addi/eori/cmpi can modify SR/CCR m68k: addq/subq can work with all the data sizes. m68k: add cmpm m68k: add exg m68k: add bkpt m68k: add cas instruction m68k: add linkl m68k: add DBcc and Scc (memory operand) m68k: add abcd, sbcd, nbcd instructions m68k: add mull/divl m68k: add addx/subx/negx m68k: shift/rotate bytes and words m68k: add rol/rox/ror/roxr m68k: add bitfield instructions cpu-exec.c | 6 - disas.c | 4 + target-m68k/cpu.c | 56 +- target-m68k/cpu.h | 33 +- target-m68k/helper.c | 817 +++++++++++++---- target-m68k/helper.h | 56 +- target-m68k/op_helper.c | 179 +++- target-m68k/qregs.def | 1 + target-m68k/translate.c | 2259 ++++++++++++++++++++++++++++++++++++++--------- 9 files changed, 2781 insertions(+), 630 deletions(-) -- 2.4.3
