HJ,
can you please check if the earlier revision is good? I do not have omnetpp
sources from spec2k6 and wonder how this particular revision can lead to a
wrong code... It only slightly changes the way we merge builtin decls that
should be a no-op because we already merge them at the streaming time.
You can build with -fdump-ipa-cgraph and look if there are any transparent
aliases introduced. (just grep the dumps for transparent_alias)
