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.
(It's more fluke than anything else that I ended up with all the first seven groupings in this set; they happened to all be easy small groupings. For some of the larger SIMD instruction groups I expect that we will end up implementing only some of the instructions in a group, in order to get more quickly to the useful milestone of "implement all the instructions gcc happens to emit today".) 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 | 1440 +++++++++++++++++++++++++++++++++++++++++++- 3 files changed, 1463 insertions(+), 9 deletions(-) -- 1.8.5
