// This file defines operations used to clean up IR for the FatLTO pipeline.
// Instrumentation that is beneficial for bitcode sections used in LTO may
// need to be cleaned up to finish non-LTO compilation. llvm.checked.load is
// an example of an instruction that we want to preserve for LTO, but is
// incorrect to leave unchanged during the per-TU compilation in FatLTO.
