Something is seriously wrong with the way gccas and gccld are being linked on
Mac OS X. For example, even though we link in libipa.a, the CallGraph analysis
and corresponding RegisterAnalysis object is not being linked into the final
gccas binary, so "gccas -o=foo < /dev/null" results in an assertion failure when
PruneEH, a CallGraphSCCPass, tries to do an addRequired<CallGraph>():

/Users/brg/llvm/include/llvm/PassAnalysisSupport.h:47: failed assertion
`Pass::getClassPassInfo<PassClass>() && "Pass class not registered!"'

The workaround is to link in too much stuff on purpose. For example, with gccas
add "ipa datastructure" instead of "ipa.a" to USEDLIBS in gccas/Makefile.

If this fixes the problem, let me know and I'll close the bug.

Thanks!

wow, I thought for sure I had something weird to show you tomorrow morning. :-P

It looks like that fixed it though. Thanks!!

Just changing the subject line to be more "citable" in release notes.
