My own gut feeling on this is that you'd be better off figuring out

how to do this in the context of Faust, which already does a important

subset of what you are describing, though notably without (I think)

the LLVM part.
Note also that hosts which run plugins at the level of LADSPA/LV2,

VST, AU, DSSI etc are unlikely to be easy candidates for any

cross-plugin optimization. I can say for sure that, for example,

Ardour3 has an object called a Processor whose ::run() method

encapsulates all DSP done within Ardour, but nevertheless it would be

more or less impossible to do any kind of optimization that looked

"across" all the Processors in a signal chain (eg. gain, pan, plugins,

etc, etc).
