<p class="MsoNormal">Dear Suresh,<br>
<br>
First, may I ask why you're using automatic pool allocation (APA)? The APA transforms have probably suffered significant bitrot; I haven't used them much in recent years. APA's current algorithms for deciding when and where to make pools are a bit complicated.
Depending on your needs, it may make more sense to morph the current APA code into something that is simpler and easier to maintain (e.g., a transform that creates global, context-insensitive pools) than to use it for doing context-sensitive pool allocation
(which requires changing function signatures which becomes tricky when the program uses external libraries).<br>
<br>
We've used DSA recently (Fall 2014), so it's in much better shape. We even have a version of it ported to LLVM 3.7 (<a href="https://github.com/jtcriswell/llvm-dsa">https://github.com/jtcriswell/llvm-dsa</a>).<br>
<br>
Second, to answer your question, the reason why you're seeing this error is because you haven't loaded the DSA libraries into opt. You need to include additional -load options to opt to load DSA. I believe the libraries you need to load (in order) are libAssistDS.so
and libLLVMDataStructure.so:<br>
<br>
opt -load AssistDS.so -load LLVMDataStructucture.so -load poolalloc.so ...<br>
<br>
An alternative to running opt is to build a simple tool which links in these libraries and runs the needed passes over the bitcode file (essentially, writing a specialized opt tool just for running these passes). The pa programs (poolalloc/tools/Pa) is an
outdated example of such a tool.<br>
<br>
Regards,<br>
<br>
