* Revert r124611 - "Keep track of incoming argument's location while emitting ↵Devang Patel2011-02-2113-144/+32
| | | | | | | | | | | | | LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126155 91177308-0d34-0410-b5e6-96231b3b80d8
* Add SplitKit::isOriginalEndpoint and use it to force live range splitting to ↵Jakob Stoklund Olesen2011-02-213-2/+32
| | | | | | | | | | | | | | terminate. An original endpoint is an instruction that killed or defined the original live range before any live ranges were split. When splitting global live ranges, avoid creating local live ranges without any original endpoints. We may still create global live ranges without original endpoints, but such a range won't be split again, and live range splitting still terminates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@126151 91177308-0d34-0410-b5e6-96231b3b80d8

Also, tweak the comment because this method can (and always could) return true without deleting the original phi node.
