[LLVMdev] Eliminating gotos

[Benedict Gaster]

Hi,

That is interesting.

Do you have any pointers to the test cases in question?

The problem is that we don't have conditional branches and so we are going
to have to do some form of goto elimination and as such do you have any
alternatives in mind?

Thanks,

Ben
