[LLVMdev] Replacing instruction in LLVM IR by an intrinsics
Hi everyone,
I am trying to write a pass, that finds some instructions and replaces them with my intrinsics,
but I am having problem understanding, how this should be done.
Let's say I have this instruction:
%tmp14 = load i32* getelementptr ([32 x i32]* @gpregs, i32 0, i64 28)
and i need to read the load's operands and replace it by let's say:
%tmp14 = call i32
