soft float and vector ABIs.  Support the generic vector ABI for
	AltiVec types.
	(do_ppc_sysv_return_value): Likewise.  Correct argument types and
	casts.
	(ppc64_sysv_abi_push_dummy_call): Assert that floating point is
	supported.
	* ppc-tdep.h (enum powerpc_vector_abi): New.
	(struct gdbarch_tdep): Add soft_float and vector_abi.
	* rs6000-tdep.c (setpowerpccmdlist, showpowerpccmdlist)
	(powerpc_soft_float_global, powerpc_vector_strings)
	(powerpc_vector_abi_global, powerpc_vector_abi_string): New.
	(rs6000_gdbarch_init): Check for soft-float and vector ABI markings.
	(set_powerpc_command, show_powerpc_command, powerpc_set_soft_float)
	(powerpc_set_vector_abi): New.
	(_initialize_rs6000_tdep): Register "set powerpc" and "show powerpc"
	commands.
	* Makefile.in (elf_ppc_h): New.
	(rs6000-tdep.o): Update.

	* gdb.texinfo (PowerPC): Document "set powerpc vector-abi" and "set
	powerpc soft-float".

	* gdb.arch/altivec-abi.exp: Run multiple times for GCC on GNU/Linux.
	Test "set powerpc vector-abi".  Skip auto-detection tests for old
	toolchains.
