* ppc-sysv-tdep.c (ppc_sysv_abi_push_dummy_call): Check the selected
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.
