Hi, I am trying to use the poolallocator. More specific, I am trying to play around with the pointer compression pass. Though, I get assertion failures for the pass dependencies. This is when it in PointerCompress::getAnalysisUsage tries to register the the BU pass as required. I.e. when AU.addRequired<CompleteBUDataStructures>(); is called. $ opt -f -load ~/Projects/llvmstuff/opt/poolalloc/lib/ libpoolalloc.dylib -raiseallocs -poolalloc-passing-all-pools - pointercompress llist-noopt.bc -o lli...

...I am still receiving the error. Another question, I do not want to use the bump ptr optimization, and I suppose that the right heuristic for that is AllNodes? But if I want to use it, what is the right heuristic? Also, if I want to use the Pointer Compression, I suppose that I have to use the -pointercompress switch with opt or what? Thanks

...istic? The AllNodes heuristic is the only one that is substantially tested. I would recommend it, none of the others have any significant performance benefit anyway. The bump pointer and other opts are a seperate option -pooloptimize, which can be run after -poolalloc. It does not work with -pointercompress though. > Also, if I want to use the Pointer Compression, I suppose that I have to > use the -pointercompress switch with opt or what? Yes, if you use it, don't specify -poolalloc manually. -Chris -- http://nondot.org/sabre/ http://llvm.cs.uiuc.edu/
