This patchseries provides the second slice of the MVE implementation. In this series: * fixes for bugs in a couple of the insns committed to upstream as part of the first slice * the logical immediate insns (including a preliminary refactoring to share the asimd_imm_const() decode between Neon, A64 and MVE) * some vector shifts * all the new MVE shift instructions which sit entirely within the non-coprocessor part of the encoding space and operate only on general purpose registers (either 32-bit shifts of one register, or 64-bit shifts of a register pair). These insns are not predicable and not subject to beatwise execution. * VADDLV (add long across vector) * VSHLC (shift left entire vector with carry in and out)
(I haven't yet got to the shift-vector-by-scalar-in-register shift insns yet; those will be in some future patchset.) This is a bit smaller than the first slice patchseries was, but softfreeze is approaching and I wanted to give this the best chance of getting through code review before then. (Not that it matters much if it doesn't, it just means I would be carrying more patches locally until we reopen for 6.2.) thanks -- PMM Peter Maydell (18): target/arm: Fix MVE widening/narrowing VLDR/VSTR offset calculation target/arm: Fix bugs in MVE VRMLALDAVH, VRMLSLDAVH target/arm: Make asimd_imm_const() public target/arm: Use asimd_imm_const for A64 decode target/arm: Use dup_const() instead of bitfield_replicate() target/arm: Implement MVE logical immediate insns target/arm: Implement MVE vector shift left by immediate insns target/arm: Implement MVE vector shift right by immediate insns target/arm: Implement MVE VSHLL target/arm: Implement MVE VSRI, VSLI target/arm: Implement MVE VSHRN, VRSHRN target/arm: Implement MVE saturating narrowing shifts target/arm: Implement MVE VSHLC target/arm: Implement MVE VADDLV target/arm: Implement MVE long shifts by immediate target/arm: Implement MVE long shifts by register target/arm: Implement MVE shifts by immediate target/arm: Implement MVE shifts by register target/arm/helper-mve.h | 108 ++++++++ target/arm/translate.h | 41 +++ target/arm/mve.decode | 177 +++++++++++- target/arm/t32.decode | 55 +++- target/arm/mve_helper.c | 524 ++++++++++++++++++++++++++++++++++-- target/arm/translate-a64.c | 86 +----- target/arm/translate-mve.c | 261 +++++++++++++++++- target/arm/translate-neon.c | 81 ------ target/arm/translate.c | 327 +++++++++++++++++++++- 9 files changed, 1465 insertions(+), 195 deletions(-) -- 2.20.1
