[LLVMbugs] Problems compiling poolalloc

[Vikram S. Adve]

Hi Michelle,

I'm glad to hear you are working with DSA again in the context of  
OpenAnalysis.  I do think it is a very good fit.  Clearly we have not  
tested some of the configuration code for llvm-poolalloc module as  
well as the mainline LLVM module.  Nevertheless, we do it regularly in  
my group, and someone at TU Dresden recently used it extensively as  
well, so the code base is at least in use and being maintained.  I  
hope John is able to help you get over the initial humps in compiling  
and using it.

Regards,
