They need to go on the PICLDR as the verifier points out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157151 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-24Materialize global addresses via movt/movw pair, this is always betterAnton Korobeynikov
than doing the same via constpool: 1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2. 2. Load from constpool might stall up to 300 cycles due to cache miss. 3. Movt/movw does not use load/store unit. 4. Less constpool entries => better compiler performance. This is only enabled on ELF systems, since darwin does not have needed relocations (yet). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89720 91177308-0d34-0410-b5e6-96231b3b80d8
