Issues

• Segment stores read fields 1..nf with the EEW of field 0: field registers written at another EEW are stored permuted

• vcompress.vm raises illegal instruction when the mask register vs1 is not a multiple of LMUL

• Masked FP compares raise exception flags from inactive elements

  pulp-platform/ara#536 · Filter by author davidharrishmc opened on Oct 20, 2026

• Strided segment accesses with the stride in x8 and indexed segment accesses with the index in v8 access only field 0

  pulp-platform/ara#535 · Filter by author davidharrishmc opened on Oct 20, 2026

• Segment loads that need a vd reshuffle corrupt vd: the segment sequencer rewrites the reshuffle as a micro-operation

  pulp-platform/ara#534 · Filter by author davidharrishmc opened on Oct 20, 2026

• vslidedown reads past VLMAX (next registers, wrapped VRF address) instead of returning 0

• Widening and FP reductions relabel the registers after vd (the whole EMUL group) with the result EEW

  pulp-platform/ara#532 · Filter by author davidharrishmc opened on Oct 20, 2026

• With vl = VLMAX, vd is not reshuffled although masked-off, tail or slid-over elements of vd are kept

• Indexed loads whose destination overlaps the lowest register of a wider index group load from wrong addresses

  pulp-platform/ara#530 · Filter by author davidharrishmc opened on Oct 20, 2026

• Masked loads with vstart past the first VRF word leave stale MASKU mask entries for the next masked op, or hang

  pulp-platform/ara#529 · Filter by author davidharrishmc opened on Oct 20, 2026

• Compare and vmadc/vmsbc mask results write 0s into tail bits past vl

• vrgather/vcompress can read vs2 before the preceding instruction has written it

  pulp-platform/ara#527 · Filter by author davidharrishmc opened on Oct 20, 2026

• vrgather.vi sign-extends its 5-bit unsigned index (uimm >= 16 is treated as out of range)

• vfredmin/vfredmax return an infinity instead of the canonical NaN when all operands are NaN

• Widening FP instructions do not raise NV for a signaling-NaN SEW operand

• fflags/fcsr accesses right after a vector FP instruction miss (or later regain) its flags

• Silent vector data corruption after e64-to-e32 reshuffle with large LMUL

• vmv.x.s returns a wrong value when integer rd and vector vs2 share a number

  pulp-platform/ara#518 · Filter by author KnightGOKU opened on Oct 13, 2026

• Legal instructions with single-register operands (mask destinations, mask operands, vlm/vsm, reduction scalars) raise illegal instruction
