Is addrspace info available during instruction scheduling?
We'd like to be able to vary the latency of our load instructions based on
what address space is being loaded from. I was thinking I could do this by
overriding getOperandLatency in our target, but I'm wondering if the
addrspace info is available when instructions are scheduled?
For example, I have this in our llvm IR:
%0 = load i32 addrspace(4)* @answer, align 4
store i32 %0, i32*
