[LLVMdev] Building poolalloc with current LLVM development branch?

First, I've never used CMake to build poolalloc. I've always used the
autoconf-based build system. It is possible that the CMake files for
poolalloc are broken. I recommend using the autoconf-based build system.
Second, you'll be pleased to know that someone (I think Will Dietz) has
gotten DSA working with mainline LLVM. The DSA code compiles, but not
the Automatic Pool Allocation optimization code. To put it another way,
poolalloc/lib/DSA compiles and works but poolalloc/lib/PoolAllocate
doesn't compile. I took a snapshot of LLVM trunk and poolalloc trunk
awhile ago and put it on Github for my students to use. You can find it
Third, my group's work on DSA is demand-driven. While several of my
students are using DSA, I do not presently plan to have them maintain or
improve DSA unless their projects require it (that said, I easily see
projects that will require enhancing DSA, so this is subject to
change). To the best of my knowledge, no one is currently using or
maintaining the Automatic Pool Allocation optimization. I have no plans
that require my group to use it or maintain it at present and don't
foresee any in the near future.
Finally, I've noticed a significant increase in the number of people
wanting to use DSA in recent months. I think this indicates a demand (I
believe from the research community) for shape graph analysis and a call
graph analysis that can handle function pointers. I'd like to better
understand who needs these features, which exact features they need, and
whether they have any interest in helping support the analyses long term.
To that end, I'd like to hold a BoF on points-to analysis/call graph
analysis at this year's LLVM Developer's Meeting to see who is
interested in these analyses, what they really need, and whether there
is a way to build something that meets those needs that can be
maintained long term.
