[LLVMdev] More efficient way of going over memory based instructions

[Villmow, Micah]

I am writing a pass for a custom backend that I am developing and I need
to iterator over all memory based instructions in a program. Currently I
iterate over all instructions in a MachineFunction, but I was wondering
if there is an efficient way that I can use that only goes over the
instructions that have MachineMemOperands that is faster than a linear
scan?

 

Thanks,

Micah
