* reimplement Constant::ContainsRelocations as Chris Lattner2009-07-225-67/+51
| | | | | | | | | | | Constant::getRelocationInfo(), which has a much simpler to use API. It still should not be part of libvmcore, but is better than it was. Also teach it to be smart about hidden visibility. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76700 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | range's weight properly. This is turned off right now in the sense that you'll get an assert if you get into a situation that can only be caused by an iterative coalescer. All other code paths operate exactly as before so there is no functional change with this patch. The asserts should be disabled if/when an iterative coalescer gets added to trunk. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76680 91177308-0d34-0410-b5e6-96231b3b80d8
