MarkedNoUnwind

return MarkedNoUnwind = false

Return ‘true’ if this is a call to a function marked ‘nounwind’.

Return ‘false’ otherwise. bool EHStreamer::callToNoUnwindFunction(const MachineInstr *MI) { assert(MI->isCall() && "This should be a call instruction!");

if (SawFunc) { Be conservative. If we have more than one function operand for this call, then we can't make the assumption that it's the callee and not a parameter to the call.

FIXME: Determine if there's a way to say that ‘F’ is the callee or
