Large code model is identical to medium code model except that the addis/addi sequence for "local" accesses is never used. All accesses use the addis/ld sequence. The coding changes are straightforward; most of the patch is taken up with creating variants of the medium model tests for large model. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175767 91177308-0d34-0410-b5e6-96231b3b80d8
