Re: [LAD] Project proposition: llvm based dsp engine

I realised that my yesterday answer miss the point a little,
so here it is a few linse of complement.

Going back to the Paul comment:

This is exactly the point: what about having a way to build the 'run' methods
for a class of applications (PD have such a method, jMax have such a method,
many others application have such a methods) that *would* allow cross plugin
optimisations for a certain class of plugins (those written or compiled according
to the engine 'native' rules) and being able to use the other plugins keeping the
glue code run time cost very low thanks to dynamic code generation.

Essentially a generic basic infrastructure using LLVM code generation and optimisation
capabilities.

And by the way, i am not sure to understand the reference to Faust, that is one of the
language/system used to define and assemble DSP algorithms, and to generate plugins,
but it is not a generic container for DSP executions, AFAIK.
