JIT: fix try region cloning when try is nested in a handler - #111975
Merged
AndyAyersMS merged 1 commit intoJan 29, 2025
Conversation
We were not placing the new EH region in the table properly, and not correctly updating the handler indexes of cloned blocks. Add some test cases where we have cloneable loops with EH inside of finallies. Fixes some issues that came up testing dotnet#111473

Are these ehGetDsc calls dead code? Ditto the ehGetDsc calls above for the try region logic.

Yeah, looks like they are.
This code has been churned quite a bit... I am still fighting off the temptation to revise the entire EH model since it is currently not update friendly. In retrospect perhaps that would have been an easier path.

I'll fix that in a subsequent PR.

Also interesting bit of trivia: methods with loops in finallys bypass tiering, since we can't OSR from a finally. |
