Now I am writing a simulator by llvm IR. That is really a wonderful
tools for us. Now I use gprof try to
find the bottleneck of the simulator, the output as the following. And
I found addRegisterDead of llvm
is called too much. What is the functionality of addRegisterDead?
I try to understand it by reading the related code of llvm source but no idea.
% cumulative self self total
time seconds seconds calls Ts/call Ts/call name
5.16 0.33 0.33
llvm::TargetRegisterInfo const*, bool)
Thanks in advance.
