This patchseries does more of the conversion of the A64 decoder to decodetree. It covers the exception-generation, system, load and store instructions.
After this the remaining legacy decoder pieces are: * data-processing (register) * data-processing (SIMD) * data-processing (floating-point) I plan to take a break from conversion after this series to work on FEAT_MOPS, but want to come back to the dp-register parts for this release cycle. The FP/SIMD stuff is a bigger job and I'm inclined to leave it for the moment. I include the LDSMIN/LDSMAX bugfix as patch 1 to avoid a conflict later. Speaking of conflicts, this is going to conflict with RTH's LSE2 series, which I expect to get in to the tree first, but I'm hoping the rebase of this series won't be too painful. thanks -- PMM Peter Maydell (20): target/arm: Fix return value from LDSMIN/LDSMAX 8/16 bit atomics target/arm: Convert hint instruction space to decodetree target/arm: Convert barrier insns to decodetree target/arm: Convert CFINV, XAFLAG and AXFLAG to decodetree target/arm: Convert MSR (immediate) to decodetree target/arm: Convert MSR (reg), MRS, SYS, SYSL to decodetree target/arm: Convert exception generation instructions to decodetree target/arm: Convert load/store exclusive and ordered to decodetree target/arm: Convert LDXP, STXP, CASP, CAS to decodetree target/arm: Convert load reg (literal) group to decodetree target/arm: Convert load/store-pair to decodetree target/arm: Convert ld/st reg+imm9 insns to decodetree target/arm: Convert LDR/STR with 12-bit immediate to decodetree target/arm: Convert LDR/STR reg+reg to decodetree target/arm: Convert atomic memory ops to decodetree target/arm: Convert load (pointer auth) insns to decodetree target/arm: Convert LDAPR/STLR (imm) to decodetree target/arm: Convert load/store (multiple structures) to decodetree target/arm: Convert load/store single structure to decodetree target/arm: Convert load/store tags insns to decodetree target/arm/tcg/a64.decode | 406 ++++ target/arm/tcg/translate-a64.c | 3183 ++++++++++++++------------------ 2 files changed, 1801 insertions(+), 1788 deletions(-) -- 2.34.1
