Register r12 ('ip') is used by GCC for this purpose and hence is used here. As discussed on the GCC mailing list, the register choice is an ABI issue and so choosing the same register as GCC means __builtin_call_with_static_chain is compatible. A similar patch has just gone in the AArch64 backend, so this is just the ARM counterpart, following the same discussion. Patch by Stephen Cross. llvm-svn: 241996
