[LLVMdev] Jump Theading/GVN bug - moving discussion to llvm-dev
Whatever we end up deciding, I think we do need to preserve the ability of a language frontend to generate complete garbage in the form of unreachable code. If we decide to move in the direction of disallowing the production of unreachable code, we need to write a canonicalization pass that runs first thing in the pipeline. A frontend should be able to produce unreachable code. This enables important simplifications in the frontend. I...

[LLVMdev] Jump Theading/GVN bug - moving discussion to llvm-dev
Hello, I encountered a problem triggered by Jump-Threading optimization. This pass is creating an unreachable block with an instruction that is not well formed, which then causes the subsequent GVN pass to enter an infinite loop. I have submitted a bug report and proposed fix to llvm-commits. This bug opened a can of worms. I was asked to move the discussion to llvm-dev to reach for a wider audience...

IAX2 REACHABLE/UNREACHABLE
All, I have an issue with IAX that I can't comprehend. Approximately every eight minutes my servers go unreachable. They stay unreachable for exactly 10ms. I have two servers running IAX and it happens on both servers simultaneously. I have searched the archives and see similar issues, but not the exact same one. I am on the current CVS stable version of *. Also, during IAX calls, every couple of minut...
