[LLVMdev] metadata to inform the optimizers that some code should stay unchanged
Hello LLVM,
I am working on some passes that perform code transformations. Since I am
interested in performance, I apply the O3 passes, right after my pass.
However, the optimization passes modify the code inserted by my pass in an
undesirable way. As far I know, there is no way to prevent the optimizers
from optimizing some regions of code. So what I intend to do is to attach
metadata to the
