...lt;*const_expr << "\n";
}
}
llvm::errs() << "\n";
}
by this method ,I want to get the instruction in the function,but there will be retrun constantExp.
for example:
in the IR:
@gNoise = common global %struct.rs_allocation.0 zeroinitializer, align 4
tail call void @_Z13rsClearObjectP13rs_allocation(%struct.rs_allocation.0* @gNoise) nounwind
%7 = load [1 x i32]* bitcast (%struct.rs_allocation.0* @gNoise to [1 x i32]*), align 4
but the user will return the use as follows:
1.tail call void @_Z13rsClearObjectP13rs_...
