* doc/tm.texi: Document TARGET_USES_WEAK_UNWIND_INFO,
TARGET_EXPLICIT_INSTANTIATIONS_ONE_ONLY, TARGET_SUPPORTS_HIDDEN,
TARGET_ASM_EMIT_UNWIND_LABEL.
* cp/decl2.c (maybe_make_one_only): Look at
TARGET_EXPLICIT_INSTANTIATION_ONE_ONLY when deciding whether
to make an explicit instantiation weak.
* cp/method.c (use_thunk): Make sure we call comdat_linkage
when appropriate.

don't go in a static archive's TOC, explicit instantiation of a
class must imply *explicit* instantiation of its memeber.

* src/ia64/ffi.c (ffi_prep_incoming_args_UNIX): Get floating point
arguments from fp registers only for the first 8 parameter slots.
Don't convert a float parameter when passed in memory.
From-SVN: r79323
* src/powerpc/ffi.c (ffi_prep_cif_machdep <FFI_LINUX64>): Correct
long double function return and long double arg handling.
(ffi_closure_helper_LINUX64): Formatting. Delete unused "ng" var.
Use "end_pfr" instead of "nf". Correct long double handling.
Localise "temp".
* src/powerpc/linux64.S (ffi_call_LINUX64): Save f2 long double
return value.
* src/powerpc/linux64_closure.S (ffi_closure_LINUX64): Allocate
space for long double return value. Adjust stack frame and offsets.
Load f2 long double return.
From-SVN: r77481
* src/sparc/ffi.c (ffi_prep_args_v9): Shift the parameter array
when the structure return address is passed in %o0.
(ffi_V9_return_struct): Rename into ffi_v9_layout_struct.
(ffi_v9_layout_struct): Align the field following a nested structure
on a word boundary. Use memmove instead of memcpy.
(ffi_call): Update call to ffi_V9_return_struct.
(ffi_prep_closure): Define 'ctx' only for V8.
(ffi_closure_sparc_inner): Clone into ffi_closure_sparc_inner_v8
and ffi_closure_sparc_inner_v9.
(ffi_closure_sparc_inner_v8): Return long doubles by reference.
Always skip the structure return address. For structures and long
doubles, copy the argument directly.
(ffi_closure_sparc_inner_v9): Skip the structure return address only
if required. Shift the maximum floating-point slot accordingly. For
big structures, copy the argument directly; otherwise, left-justify the
argument and call ffi_v9_layout_struct to lay out the structure on
the stack.
* src/sparc/v8.S: Undef STACKFRAME before defining it.
(ffi_closure_v8): Pass the structure return address. Update call to
ffi_closure_sparc_inner_v8. Short-circuit FFI_TYPE_INT handling.
Skip the 'unimp' insn when returning long doubles and structures.
* src/sparc/v9.S: Undef STACKFRAME before defining it.
(ffi_closure_v9): Increase the frame size by 2 words. Short-circuit
FFI_TYPE_INT handling. Load structures both in integers and
floating-point registers on return.
* README: Update status of the SPARC port.
