Starting with the Haswell micro-architecture, the indirect branch predictor got much better and a plain switch statement is just as fast as the "computed goto" equivalent. Be wary of any references about this that are from before 2013.
That needs an 2011 tag.
I wonder if Clang can do better these days; I noticed that it seems to merge computed gotos to normal-looking control-flow (I suppose this is necessary for alias analysis).
Is LuaJIT still under active development? I thought the developer had walked away. With Torch also looking dead, that use case is gone, too. Roblox has their own Lua VM now.
I love Lua and code in it almost every day for fun, but yeah I'm pretty sure LuaJIT is just "done" now?
