Faster luaL_addlstring #465

mingodad · 2019-01-08T20:24:20Z

Converting LuaJIT to LjsJIT https://github.com/mingodad/ljsjit and making some tests I found that the api function luaL_addlstring in lua 5.1 and LuaJIT is a lot slower than more recent Lua versions so using the luaL_addvalue as base I reimplemented luaL_addlstring and it's now on par with lua 5.3.5
