When looking at issue #99543 , a fair amount of time was spent trying to understand how the relationship of a basic blocks' IL offsets, bbCodeOffs/bbCodeOffsEnd, correspond to the blocks' statements' DebugInfo they contain.

Items to investigate:

  • What is not clear is what should happen to the basic blocks' IL offsets if the statements they contain are modified/transformed (during a Debug compilation).

Good point. I think we are not consistent in maintaining IL offset when merging/spliting basic blocks.
