Daniel Dunbar de46097847 ccc: Allow downstream tools to be aware of final output name.
- This is a hack to allow the Darwin linker to get -final_output when
   doing universal builds; the mechanism should be generalized.

 - Handle multiple redundant -arch arguments correctly.

 - Forward -arch_multiple and -final_output to gcc when necessary.

 - Simplified implementation of derived gcc tools.

llvm Fix PR3243: a LiveVariables bug. When HandlePhysRegKill is checking whether the last reference is also the last def (i.e. dead def), it should also check if last reference is the current machine instruction being processed. This can happen when it is processing a physical register use and setting the current machine instruction as sub-register's last ref. 2009-01-20 21:25:12 +00:00
