WitrynaIn addition to register operations, RISC-V instructions can use constant or immediate operands. These constants are called immediates because their values are immediately available from the instruction and do not require a register or memory access. Code Example 6.6 shows the add immediate instruction, addi, that adds an immediate to a … Using the sign-extended-imm8 encoding when available is always good. It's equal length for 16-bit, but shorter for 32-bit operand-size, so it simplifies your code to always choose imm8. With operand-size of 32-bit, op eax, imm32 is 5 bytes, vs. op r/m32, imm8 still being 3 bytes. (Not counting any prefixes needed to set operand-size or other ...
