r246619, thanks! About createEliminateAvailableExternallyPass for LTO, I'm missing something. At link time, aren't available externally function supposed to be, well, available as external linkage? Won't the link fail without these versions? if so, why keep the available externally versions at all for LTO instead of using the external linkage versions?
