![]() ![]() If you implement a safe language with the JIT, you can't have buffer overflows :)As I've said, possible BOFs unrelated to JIT. This can be a very good reason if your project is supposed to be multiplatform (however doesn't really matter for a kernel which has non-portable Assembly and platform-specific parts anyway). Minetest is a good example, you can compile it with Lua JIT as well as with interpreted Lua, despite of this the engine is shipped with interpreted Lua by default.įinally, although I haven't though of this until now, you can write a portable interpreter, but it is not possible to write a portable JIT compiler. Interpreter might be slower in general, but has a smaller and more flattened and constant overhead (therefore calculateable, no peaks). There the peaking overhead of forking and somehow applying back the info from the compiler process what to map as executable is just too much and unaffordable. Ok, let's have another typical example, a game engine which loads objects on-the-fly and uses JIT compiled event handlers in them. (With two tabs open right now, my browser has seven processes.)And that is highly inefficient and wasteful already! Nobody every solved anything by making things worse The smaller overhead of an interpreter would be a far better choice IMHO, and then you could have one process per tab, and the browser probably wouldn't need 1G of RAM to display a plain simple 1k HTML file. #2 0x000000000073eb16 in EmergeThread::Thread (this=0xc35ce0) at /home/minetest/minetest_core/src/emerge.It's not very different from what they already do.
