[LLVMdev] poolallocation error

[Prakash Prabhu]

Hi John,

Thanks for the fix! It is working properly now :) :

$ opt -load /home/pprabhu/llvm/llvm-install-x86-64/lib/libLLVMDataStructure.so
-stats -ds-aa -ipconstprop < prog.bc
WARNING: You're attempting to print out a bitcode file.
This is inadvisable as it may cause display problems. If
you REALLY want to taste LLVM bitcode first-hand, you
can force output with the `-f' option.
