[LLVMdev] Accessing an empty machine function before instruction selection?
I'm trying to access the MachineFunctionInfo structure from a pre-ISel pass. In order to do this I have to get access to the MachineFunction and then call getInfo().
Currently in my pass I request it via:
void AMDILBarrierDetect::getAnalysisUsage(AnalysisUsage &AU) const
{
AU.addRequired<MachineFunctionAnalysis>();
FunctionPass::getAnalysisUsage(AU);
}
However, I am getting an assert:
assert(NormalCtor &&
"Cannot call createPass on PassInfo without default ctor!");
First quest...
