The getPointerRegClass() hook can return register classes that depend on the calling convention of the current function (ptr_rc_tailcall). So far, we have been able to infer the calling convention from the subtarget alone, but as we add support for multiple calling conventions per target, that no longer works. Patch by Yiannis Tsiouris! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156328 91177308-0d34-0410-b5e6-96231b3b80d8
