[LLVMdev] data exchange between loadable pass and backend

[Nico]

Hello,

I have an analysis pass and a target machine class, both in different  
dynamically loadable libraries (plugins). There is no problem to use  
the analysis pass (opt -load=libanalysis.dylib -barpass foo.bc), but  
is it possible to get data from the analysis pass (by getAnalysis)  
while using the backend?
AFAIK it is only allowed to have one plugin argument for llc (like:  
llc -load=libbackend.dylib -march=foo bar.bc). Did I miss something?

Is the only solution to put the analysis pass in the target machine  
library?

Thanks,
Nico
