Load quadruple
This instruction is defined by:
Synopsis
Loads a 128-bit value from memory into register rd.
It computes an effective address by adding the zero-extended offset, scaled by 16,
to the base address in register rs1.
It expands to lq rd, offset(rs1).
Decode Variables
Bits<9> imm = {$encoding[12:11], $encoding[6:5], $encoding[10], 4'd0};
Bits<3> rd = $encoding[4:2];
Bits<3> rs1 = $encoding[9:7];Execution
