...I've isolated the recent additions that cause the issue and supplied a patch which is NOT meant to be applied, but instead solely exists for identification purposes for those who know what they are doing. :-) The patch is offset from HEAD. The patch is a hack which removes use of the MCSymbol::isDefined(...) method, as its use happens to break in the exception JIT context; both in MachineModuleInfo.:: TidyLandingPads(...) and in JITDwarfException:: EmitFrameMoves(...). In this context these symbols are not defined but rather are temporaries. Beyond this I don't understand what the correct repl...

Forgot to add platform with issue: OS X 10.6.2. I have not tested elsewhere.

Hi Chris, The MCSymbol r98459 patch of llvm seems to have broken the ExceptionDemo example. As the example is dying in the associated personality's first unwind search phase, which happens to have no language specific context, and is returning a _URC_CONTINUE_UNWIND, I believe the issue is generic and not specific to the example. However I'm not sure why then this wasn't seen in one

Are there any utility classes, similar to IRBuilder, for creating source level debugging info? -- Talin

I don't think so. Contribution welcome! :-) LLVM debugging support isn't anywhere near where it needs to be.
