Hi all, I have implemented a GC plugin and i want to exclude Tail-call instructions from being considered as Safe Points. For that reason I have overwritten the "findCustomSafePoints" function with something like that: bool ErlangGC::findCustomSafePoints(GCFunctionInfo &FI, MachineFunction &MF) { for (MachineFunction::iterator BBI = MF.begin(),

...ents are promoted to registers and the rest to the stack, and the callee is responsible for popping the stack arguments. So when calling a function with 5 arguments i get this code: movq ARG_5, (%rsp) callq fun_foo_1 .Ltmp4: subq $8, %rsp I use a garbage collector with postcall safe points (.Ltmp4 is such) which needs to know the frame size, for each safe point. The problem is that at .Ltmp4 the frame size is actually different from what getFrameSize() would return. So is there a way to force generation of code which pushes arguments ? For example : pushq ARG_5 call...

You can also override this behavior and examine each instruction and return a boolean indicating whether it is or isn't a safe point. Currently I only have function calls as safe points, although I may eventually enable loops as well. As far as leaf functions go, consider that the call to all...

Talin, do you identify safe-points in the current or proposed llvm scheme, and if so how, or are they implicit as being at all call sites (which begs the question what about leaves in the call tree, how does GC get started at all in that case). Peter Lawrence.

Obviously, I have a dialplan / context problem, but I'd appreciate a brief explanation and some direction from the group! In extensions.conf, I have [from-pstn].

Hi All- I am trying to create a post call survey application. I would like to: 1. ask the caller if they want to take a survey after their call completes 2. If no, just transfer the call 3. if yes, 4. bridge up another extension 5. wait for that extension to hang-up 6. have the system (not the user) transfer the call to different extension that administers an IVR based survey. Anyone

I've been beating myself up over this script but clearly I'm missing something. If I enter an extension like 101 it rings through fine, but if I pick 2 for sales it hangs up with this message: == Spawn extension (sales, s, 1) exited non-zero on `Zap/1-1' Since I'm not sure what that exacly means I cannot take appropriate action. Any help would be appreciated. [default]
