For this model to be effective, it requires that the transitions between Lua and C++ be as fast as …
Compilers, VM, and Bytecode
- When Lua source code is compiled, it’s compiled into Lua bytecode, which the Lua VM then runs. Lua bytecode has around 35 instructions in total, for things like reading/writing tables, calling functions, performing binary operations, jumps and conditionals, and so on. The Lua VM is register-based, as opposed to being stack-based like many other VMs, so part of what the compi…
Basic Bytecode Examples
- A simple program like “x = 10” compiles into: The first two lines show the constant table (with the string value “x” in slot 0 and the integer value 10 in slot 1), and the following two lines are the disassembled opcodes. [Line 1] Looking up the LOADK opcode in “No Frills,” we see that it has the form “LOADK A Bx — R(A) := Kst(Bx).” So, LOADK has two arguments (registers A and B) and its …
Bytecode For Function Calls
- Let’s look at the code generated for “foo(10):” To execute function calls, the function must be loaded into the first register and arguments into subsequent ones. The semantics for “CALL A B C” are such that A holds the function, B is the number of arguments (actually, it’s the number of arguments +1, due to the way “…” is implemented), and C is the number of return values (again, it…
Member Function Calls
- Okay, back to looking at some bytecode! This next example is a bit more interesting because it shows what happens when you have code like “foo:bar(10),” which is calling the bar method on the instance foo (an instance of the class Foo). The new thing here is the self instruction [line 2], which we haven’t seen before. Self has the syntax “SELF A B C — R(A) := R(B)[RK(C)]; R(A+1) := R…
The Home Stretch!
- Now that we can clearly see the two round trips from Lua to C++, we can try to figure out how to optimize this. Our end goal is to do a single function call from Lua to C++ and have all the pieces we need on the Lua stack to be able to do method lookup and invocation at once. The problem seems to be that we have one register too few. When we call our combined lookup/invoker funct…
Conclusion
- How much of an impact does this optimization have? Well, like most things in programming, the answer is “it depends.” For functions that are heavyweight—and you don’t call that often—you won’t see much of an improvement. But for smaller functions that you call often, the savings can be considerable. People on the Developer Forumquickly noticed the appearance of this strange, …
