Description
Очень плохой вариант:
op slli(rd: X, rs1: X, imm: card(SHLEN))
syntax = format("slli %s, %s, 0x%x", rd.syntax, rs1.syntax, imm)
image = format("000000%1s%5s%s001%s0010011",
if SHLEN == 6 then imm<5> else coerce(BIT, 0) endif,
if SHLEN == 5 then imm else imm<4..0> endif,
rs1.image,
rd.image
)
action = {
rd = rs1 << imm;
}
Бит imm<5> для 32х битной версии не существует, а в коде есть.

Правильная версия:
op slli(rd: X, rs1: X, imm: card(SHLEN))
syntax = format("slli %s, %s, 0x%x", rd.syntax, rs1.syntax, imm)
@rev(RV64I)
image = format("000000%1s%5s%s001%s0010011", imm<5>, imm<4..0>, rs1.image, rd.image)
#ifndef RV64I
@rev(RV32I)
image = format("000000%1s%5s%s001%s0010011", coerce(BIT, 0), imm<4..0>, rs1.image, rd.image)
#endif
action = {
rd = rs1 << imm;
}
