...l outside of the _finally clause, a "local-unwind" must be triggered to properly invoke _finally clauses alone the path from the goto statement to the target label. Since _finally clause can be executed in either "normal execution path" as well as "exception path", the _local_unwind can take place in both paths too. Let's demonstrate all possible paths in the following example. try { try { try { /* set counter = 1 */ Counter += 1; if (ex) RtlRaiseException(&ExceptionRecord); } finally { Counter += 1; if (abnorm...

...be there's something obvious here I'm missing, but it looks like essentially the same problem, and I don't see any reason why we can't use the existing solution. No, no new mechanism is invented. The design employs the existing mechanism to model the third exception path caused by _local_unwind (in addition to normal execution and exception handling flow). In earlier discussion with Joseph, adding second EH edge to InvokeInst was briefly discussed, but was quickly dropped as it's clearly a long shot. Yes, right, it's not really a big extension of the fundamental model. It still...

Resending; I accidentally dropped llvm-dev. -Eli From: Eli Friedman Sent: Wednesday, April 1, 2020 1:01 PM To: Ten Tzen <tentzen at microsoft.com> Cc: aaron.smith at microsoft.com Subject: RE: [EXT] [llvm-dev] [RFC] [Windows SEH] Local_Unwind (Jumping out of a _finally) and -EHa (Hardware Exception Handling) This looks like it outlines the implementation pretty well. For goto in finally,

Hi, Per Reid’s feedback, I have separated two SEH missing features. This thread now is only focusing on _local_unwind(), Jumping out of _finally. The design is documented in Wiki here: https://github.com/tentzen/llvm-project/wiki/Windows-SEH:-Local_Unwind-(aka:-Jumping-Out-of-_Finally) The implementation can be seen here: https://github.com/tentzen/llvm-project/compare/SEH-LU-base...SEH-LU?expand=1 There are onl...
