[cfe-dev] Kling Clang

[Click Nilson]

Sorry, sent this to Daniel off list but not the list itself:

Thanks for the comments, 

I need to prepare this work as a SuperCollider UGen in a less hacky way, but it should be made available (under GNU GPL 3)  later in October I hope. Will be announced on the SuperCollider sc-users list, and available from my code page here: 
http://www.cogs.susx.ac.uk/users/nc81/code.html
there is already a draft LLVM UGen there already, but it only really works with IR byte codes sent from Impromptu (itself based on Scheme), and then only in an extremely messy way. 

cheers,
Nick

You can see the UGen in the graph ring modulated with the SinOsc, and taking input from audio in. The text document of C code is compiled on command (I press F1), the file written out to disk, clang run on it to get IR, which is then passed over to the UGen via Open Sound Control as a long string. The ClangUGen then interprets the IR, and substitutes the dsp function when it is safe to do so (ie not during the middle of an audio callback). This is a rough cut; there are all sorts of refinements to make including double buffering with dsp function crossfades, but hope you enjoy!
