Hi all: This question is related to a state machine generated by LLVM for a coroutine. I stripped all coroutine related details to get to the essence of the question. Let's say I have a state machine that looks like this: struct State { FnPtr Fn; State() : Fn(&SomeFunction) {} void Go() { (*Fn)(); } void Stop() { Fn = nullptr; } bool IsDone() { return Fn == nullptr; } }; Fn field serves two purposes: * Cheap check for done. What can be better than compare with zero! * Guard against programmer mistake: accidental...

...u can tell it where to insert all subsequently created instructions. This means you end up writing code like this: LLVMBuilder B; B.SetInsertPoint(<where-ever>); Value *V1 = B.CreateAdd(a, b, "tmp"); Value *V2 = B.CreateMul(V1, c, "whatever"); Value *V3 = B.CreateCall(FnPtr, V1, V2); ... The name strings are c strings, are always at the end of the argument list, and are always optional. This API is simple and consistent, which makes it easy to understand. It would also be really easy to build a C api for it, if someone is interested (hint hint :), -Chris --...

Hi Chandler, Philip, Mehdi, (and llvm-dev,) (this is partially a summary of some discussions that happened at the last LLVM bay area social, and partially a discussion about the direction of the CGSCC pass manager) A the last LLVM social we discussed the progress on the CGSCC pass manager. It seems like Chandler has a CGSCC pass manager working, but it is still unresolved exactly which
