He probably didn't. Note the simple call: %foo = call i32 @foo(i32 1, i32 2, i32 3) ; <i32> [#uses=1] This means closures aren't supported, and therefore also no fthreads. However supporting these shouldn't be hard. The problem is Erick is driving off the early bound, unoptimised code, at which point the only safe way to support fthreads and closures is to implement closures for ALL calls. After optimisation etc has run, you can tell whether you need a closure or the machine stack will suffice (and most functions would have been inlined away anyhow). Another thing probably not supported running off early bound code is polymorphic functions .. more precisely, schema (aka templates). These are monomorphised by the optimisation process, another reason to drive LLVM off the back side of the front end. Erick is trying to make a REPOL loop work AND support LLVM. The latter should be quite possible. The former is going to be very hard because Felix doesn't even support separate compilation: it was designed from the ground up as a whole program analyser. However it isn't impossible to "trick" the system by running a whole program, and then when you type in a line .. running the whole thing with that line added again (or something like that). More precisely, you'd throw out side effecting calls such as print statements but keep the definitions. To do that, Erick will need some way to tell what needs to be kept and what doesn't, but that doesn't sound too hard (although reality might be different): keep everything except procedure calls :) -- john skaller skal...@users.sourceforge.net ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
