* src/powerpc/ffitarget.h (ffi_abi): Add FFI_LINUX and
FFI_LINUX_SOFT_FLOAT to the POWERPC_FREEBSD enum.
Add note about flag bits used for FFI_SYSV_TYPE_SMALL_STRUCT.
Adjust copyright notice.
* src/powerpc/ffi.c: Add two new flags to indicate if we have one
register or two register to use for FFI_SYSV structs.
(ffi_prep_cif_machdep): Pass the right register flag introduced above.
(ffi_closure_helper_SYSV): Fix the return type for
FFI_SYSV_TYPE_SMALL_STRUCT. Comment.
Adjust copyright notice.

* src/powerpc/ffitarget.h: Introduce new ABI FFI_LINUX_SOFT_FLOAT.
Add local FFI_TYPE_UINT128 to handle soft-float long-double-128.
* src/powerpc/ffi.c: Distinguish between __NO_FPRS__ and not and
set the NUM_FPR_ARG_REGISTERS according to.
Add support for potential soft-float support under hard-float
architecture.
(ffi_prep_args_SYSV): Set NUM_FPR_ARG_REGISTERS to 0 in case of
FFI_LINUX_SOFT_FLOAT, handle float, doubles and long-doubles according
to the FFI_LINUX_SOFT_FLOAT ABI.
(ffi_prep_cif_machdep): Likewise.
(ffi_closure_helper_SYSV): Likewise.
* src/powerpc/ppc_closure.S: Make sure not to store float/double
on archs where __NO_FPRS__ is true.
Add FFI_TYPE_UINT128 support.
* src/powerpc/sysv.S: Add support for soft-float long-double-128.
Adjust copyright notice.

* src/powerpc/ffitarget.h (enum ffi_abi): Add FFI_LINUX. Default
for 32-bit using IBM extended double format. Fix FFI_LAST_ABI.
* src/powerpc/ffi.c (ffi_prep_args_SYSV): Handle linux variant of
FFI_TYPE_LONGDOUBLE.
(ffi_prep_args64): Assert using IBM extended double.
(ffi_prep_cif_machdep): Don't munge FFI_TYPE_LONGDOUBLE type.
Handle FFI_LINUX FFI_TYPE_LONGDOUBLE return and args.
(ffi_call): Handle FFI_LINUX.
(ffi_closure_helper_SYSV): Non FFI_LINUX long double return needs
gpr3 return pointer as for struct return. Handle FFI_LINUX
FFI_TYPE_LONGDOUBLE return and args. Don't increment "nf"
unnecessarily.
* src/powerpc/ppc_closure.S (ffi_closure_SYSV): Load both f1 and f2
for FFI_TYPE_LONGDOUBLE. Move epilogue insns into case table.
Don't use r6 as pointer to results, instead use sp offset. Don't
make a special call to load lr with case table address, instead
use offset from previous call.
* src/powerpc/sysv.S (ffi_call_SYSV): Save long double return.
* src/powerpc/linux64.S (ffi_call_LINUX64): Simplify long double
return.
