2009-07-22remove the SelectSectionForMachineConst hook, replacing it withChris Lattner
a new getSectionForMergableConstant hook. This removes one dependence of TAI on Type, and provides the hook with enough info to make the right decision based on whether the global has relocations etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76705 91177308-0d34-0410-b5e6-96231b3b80d8

that allows late codeine passes to delete it. This is considered a workaround. The problem is some targets are not modeling side effects correctly. PPC is apparently one of those. This patch allows ppc llvm-gcc to bootstrap on Darwin. Once we find out which instruction definitions are wrong, we can remove the PPCInstrInfo workaround. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76703 91177308-0d34-0410-b5e6-96231b3b80d8

2009-07-22reimplement Constant::ContainsRelocations as Chris Lattner
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

2009-07-21Add some support for iterative coalescers to calculate a joined liveDavid Greene
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

2009-07-21add an API so target-independent codegen can determine if a constantChris Lattner
pool entry will require relocations against it. I implemented this conservatively for ARM, someone who is knowledgable about it should see if this can be improved. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@76678 91177308-0d34-0410-b5e6-96231b3b80d8
