[Soot-list] Hot to get Block from Unit

[Eric Bodden]

Hi.

You would have to create a global data structure that caches BlockGraphs. Soot does not support this otherwise, as we have found that having blocks is usually rather useless in practice.

Best wishes

In LLVM, Instruction class has a field to its parent block, but in Soot it seems that the BlockGraph and blocks is only dynamically created from a list of units upon request. So the units are unique and global, but the blocks are re-created each time. So I was wondering if there's a low-overhead way of doing this. Thanks!
