Vector Arithmetic

v_min_u16

Select the minimum of two unsigned 16-bit integer inputs and store the selected value into a vector register.

Encoding

Verified bit-level encoding data is not yet available for this instruction. The instruction-format classification below (VOP2) is well-documented and stable; exact per-target opcode/field bit positions have not yet been imported from a verified source.
Format VOP2

Operands

  • 1: VGPR
    Vector general-purpose register, one value per lane. Written v5 in the assembler example.
  • 2: VGPR
    Vector general-purpose register, one value per lane. Written v1 in the assembler example.
  • 3: VGPR
    Vector general-purpose register, one value per lane. Written v2 in the assembler example.

Register classes read from the LLVM assembler example on this page. No source this site uses names these operands, so no names are given.
