getting code ranges of multiple blocks and prevent reordering?
Hi. I'm very new to LLVM.
For reasons to do with custom exception handling, we have a need to check IP/PC at runtime against code ranges. This can encompass multiple logically adjacent blocks.
How to do this?
I'm guessing:
insert a label at end of every block, takes it address, store that somewhere in our data; preferably as an offset from module or function start, but full address
