Pseudo Instruction

Pseudo instruction is an asm instruction which cannot be rendered directly, but needs to be translated into one or several [simple instructions](@/concepts/simple_instruction.md) first.

Simple pseudo instructions' translating can be done by a template which map a pseudo instruction to one or several simple instructions directly.

Complex pseudo instructions' translating may be depending on its params, and cannot be done with directly template mapping. For example, li instruction can be translated into a single addi instruction with a zero register as the first param when the immediate value has only 12 bits, but needs to be translated into two lui and addi instructions if the immediate value has more than than 12 bits.
