	* config/sparc/sol2-sld-64.h (TRANSFER_FROM_TRAMPOLINE): Define.
	* config/sparc/sparc.c (sparc64_initialize_trampoline): If that is
	defined, emit libcall to __enable_execute_stack.  Also fix opcodes
	and offsets in actual stack trampoline code so they match the
	commentary and actually work.

	* configure.in (sparcv9-*-solaris): Use t-sol2 and t-sol2-64 for
	tmake_file.
	(sparc64-*-linux): Use t-linux and sparc/t-linux64 for
	tmake_file.  Set extra_parts to needed crt objects.
	* configure: Rebuilt.
	* config/sparc/linux64.h (SPARC_BI_ARCH): Define.
	(TARGET_DEFAULT): Set if default is v9 or ultra.
	(STARTFILE_SPEC32, STARTFILE_SPEC64): New macros.
	(STARTFILE_SPEC): Set to those upon SPARC_BI_ARCH.
	(ENDFILE_SPEC32, ENDFILE_SPEC64, ENDFILE_SPEC): Likewise.
	(SUBTARGET_EXTRA_SPECS, LINK_ARCH32_SPEC, LINK_ARCH64_SPEC,
	LINK_SPEC, LINK_ARCH_SPEC): Likewise.
	(TARGET_VERSION): Define.
	(MULTILIB_DEFAULT): Define.
	* config/sparc/sparc.h (CPP_CPU_DEFAULT_SPEC): Rearrange so that
	mixed 32/64 bit compilers based upon SPARC_BI_ARCH work.
	(CPP_CPU64_DEFAULT_SPEC, CPP_CPU32_DEFAULT_SEC): Define
	appropriately.
	(TARGET_SWITCHES): Allow ptr32/ptr64 options once more.
	* config/sparc/sparc.c (sparc_override_options): If arch and
	pointer size disagree, emit diagnostic and fix it up.  If
	SPARC_BI_ARCH and TARGET_ARCH32, set cmodel to CM_32.  Turn off
	V8PLUS in 64-bit mode.
	* config/sparc/t-linux64: New file.
	* config/sparc/t-sol2-64: New file.
	* config/sparc/t-sol2: Adjust build rules to use MULTILIB_CFLAGS.
	* config/sparc/sol2-sld-64.h (SPARC_BI_ARCH): Define.
	(ASM_CPU32_DEFAULT_SPEC, ASM_CPU64_DEFAULT_SPEC,
	CPP_CPU32_DEFAULT_SPEC, CPP_CPU64_DEFAULT_SPEC): Define.
	(ASM_SPEC, CPP_CPU_SPEC): Set appropriately based upon those.
	(STARTFILE_SPEC32, STARTFILE_SPEC32, STARTFILE_ARCH_SPEC):
	Define.
	(STARTFILE_SPEC): Set approriately based upon those.
	(CPP_CPU_DEFAULT_SPEC, ASM_CPU_DEFAULT_SPEC): Set based upon
	disposition of DEFAULT_ARCH32_P.
	(LINK_ARCH32_SPEC, LINK_ARCH64_SPEC): Define.
	(LINK_ARCH_SPEC, LINK_ARCH_DEFAULT_SPEC): Set based upon those.
	(CC1_SPEC, MULTILIB_DEFAULTS): Set based upon DEFAULT_ARCH32_P.
	(MD_STARTFILE_PREFIX): Set correctly based upon SPARC_BI_ARCH.
	* config/sparc/xm-sysv4-64.h (HOST_BITS_PER_LONG): Only set on
	arch64/v9.
	* config/sparc/xm-sp64.h (HOST_BITS_PER_LONG): Likewise.
