    • Disable .gnu.attributes tags in compatibility-ldbl.o · 6d49b790 
      compatibility-ldbl.o is compiled with -mlong-double-64.  When
long double .gnu.attributes tags are checked by the linker, it
complains about the mismatch between this file and others in
libstdc++.

	* configure.ac (LONG_DOUBLE_COMPAT_FLAGS): New ACSUBST.
	* src/Makefile.am (compatibility-ldbl.o, compatibility-ldbl.lo):
	Use LONG_DOUBLE_COMPAT_FLAGS.

    • [RS6000] .gnu.attributes Tag_GNU_Power_ABI_FP · e9dda04f 
      Extend this attribute to cover long double ABIs, for 64-bit too.

This patch also corrects an error that crept in to code setting
rs6000_passes_float.  See the added comment.  Passing IEEE128 values
in vsx regs ought to set both Tag_GNU_Power_ABI_FP and
Tag_GNU_Power_ABI_Vector.  Also adds a new option, default on, that
disables output of .gnu_attribute assembly directives.

	* config/rs6000/sysv4.opt (mgnu-attribute): New option.
	* doc/invoke.texi: Document it.
	* config/rs6000/rs6000.c (HAVE_LD_PPC_GNU_ATTR_LONG_DOUBLE): Define.
	(rs6000_passes_float): Comment.
	(rs6000_passes_long_double): New static var.
	(call_ABI_of_interest): Return false unless rs6000_gnu_attr is set.
	(init_cumulative_args): Set up to emit fp .gnu_attribute for
	ELF 64-bit ABIs as well as 32-bit ELF.  Correct rs6000_passes_float
	to include fp values returned in vectors.
	Set rs6000_passes_long_double.
	(rs6000_function_arg_advance_1): Likewise for function args.
	(rs6000_elf_file_end): Emit fp .gnu_attribute for ELF 64-bit ABIs,
	and SPE.  Emit long double tag value too.
	(rs6000_opt_vars): Add gnu-attr.
	* configure.ac (HAVE_LD_PPC_GNU_ATTR_LONG_DOUBLE): New ppc32 test.
	* configure: Regenerate.
	* config.in: Regenerate.
