luaasm

Assembler for Lua Bytecode

Example

.fn(R0)

.instruction
GETTABUP  R1 U0 K1
GETTABLE  R1 R1 K2
GETTABLE  R2 R0 K3
CALL      R1 2 2
SETTABLE  R0 K0 R1
RETURN    R0 1

.const
K0 = "accuracy_flash"
K1 = "Accuracy"
K2 = "create"
K3 = "task_form"

.upvalue
U0 = L1 R23

.endfn

• function with variable arguments should be declared like .fn(R0, __va_args__)
• nested function should be placed between end of .upvalue and .endfn
• you may produce luaasm samples with PyLuaDec python3 dis.py <LUA_BYTECODE_FILE> luaasm
