Chris Lattner 7c981a79f7 allocate and dellocate objc decl list through AST Context instead of 
with new/delete.  With disable-free, this reduces the number of 4/8 byte
mallocs from 4793/1541 to 865/456 and also drops other sizes as well.

This is a very small perf win, nothing major.

Chris Lattner 2229872d2f add plumbing to get ASTContext& down to allocation/deallocation points in ObjCList, 
but don't start using it yet.  Renamed some methods to be more consistent.

Ted Kremenek b087942765 Greatly simplify the logic in ExplodedGraphImpl::TrimGraph. Now we just do a 
vanilla reverse-BFS followed by a forward-DFS instead of resulting to strange
histrionics (whose purpose I can no longer remember) in the reverse-BFS stage.
This fixes an assertion failure in BugReporter due to edge cases where no root
was being hit in the reverse-BFS phase.

Daniel Dunbar 5006f4a5f0 Take advantage of noreturn attribute to add unreachable instruction & 
clear insertion point. The rest of IRgen should theoretically take
advantage of this to avoid emitting dead code. Theory != Practice.

 2009-02-20 17:04:14 +00:00
Zhou Sheng 6a0634d423 patch to update the line number information in pass -mem2reg. 
Currently this pass will delete the variable declaration info, 
and keep the line number info. But the kept line number info is not updated, 
and some is redundant or not correct, this patch just updates those info.

Owen Anderson 81db491b7f Add a quick pass to the stack slot colorer to eliminate some trivially redundant spills after coloring. 
Ideally these would never get created in the first place, but until we enhance the spiller to have a more
global picture of what's happening, this is necessary for code quality in some circumstances.
