	* 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.
Thu Sep 24 01:19:02 1998  Jakub Jelinek  <jj@sunsite.ms.mff.cuni.cz>
	* 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.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
