Sorry about the tardiness of my reply. My mail client has playing tricks with me. :-) I am assuming the issue has nothing to do the branch to jumptable instructions but rather the MachineJumpTableInfo associated with every MachineFunction? If so, please take a look at BranchFoldiing.cpp for an example.

Hi all, I have a pass to break critical edges of Machine Basic Blocks, but I just discovered a bug (when compiling code for x86). The problem is 'jumpl *%reg'. I don't know how to update the jump table for this type of instruction. The code that I had (see below) does not update the jump table, and the actual branch keeps jumping to the old basic block, instead of the new.
