This is an initial set of patches which make a start on SIMD (Neon) emulation in the A64 decoder. The patches implement all the SIMD load/store operations, provide a decoder skeleton for the SIMD dp instructions, and implement all the instructions in the ARM ARM's groupings C3.6.1 through C3.6.7. Changes v1->v2: * minor tweaks as suggested by rth (noted more specifically below the fold in the affected patches) * reworked EXT to do vector accesses outside do_ext64 and thus avoid accessing the middle element twice * fixed incorrect handling of rn==sp, cleaned up tcg_rn code in the ld/st single and multiple patches thanks -- PMM Alex Bennée (4): target-arm: A64: Add SIMD ld/st multiple target-arm: A64: Add decode skeleton for SIMD data processing insns target-arm: A64: Add SIMD copy operations target-arm: A64: Add SIMD modified immediate group Michael Matz (3): target-arm: A64: Add SIMD TBL/TBLX target-arm: A64: Add SIMD ZIP/UZP/TRN target-arm: A64: Add SIMD across-lanes instructions Peter Maydell (3): target-arm: A64: Add SIMD ld/st single target-arm: A64: Add SIMD EXT target-arm: A64: Add SIMD scalar copy instructions target-arm/helper-a64.c | 31 + target-arm/helper-a64.h | 1 + target-arm/translate-a64.c | 1454 +++++++++++++++++++++++++++++++++++++++++++- 3 files changed, 1477 insertions(+), 9 deletions(-) -- 1.8.5 _______________________________________________ kvmarm mailing list kvmarm@xxxxxxxxxxxxxxxxxxxxx https://lists.cs.columbia.edu/cucslists/listinfo/kvmarm
