* Makefile.def (target_modules): Add libssp. * configure.in (target_libraries): Add target-libssp. * configure: Rebuilt. * Makefile.in: Rebuilt. gcc/ * gcc.c (LINK_SSP_SPEC): Define. (link_ssp_spec): New variable. (LINK_COMMAND_SPEC): Add %(link_ssp). (static_specs): Add link_ssp_spec. * configure.ac (TARGET_LIBC_PROVIDES_SSP): New test. * configure: Rebuilt. * config.in: Rebuilt. * config/rs6000/linux.h (TARGET_THREAD_SSP_OFFSET): Define. * config/rs6000/linux64.h (TARGET_THREAD_SSP_OFFSET): Likewise. * config/i386/linux.h (TARGET_THREAD_SSP_OFFSET): Likewise. * config/i386/linux64.h (TARGET_THREAD_SSP_OFFSET): Likewise. * config/rs6000/rs6000.md (stack_protect_set, stack_protect_test): If TARGET_THREAD_SSP_OFFSET is defined, use -0x7010(13) resp. -0x7008(2) instead of reading __stack_chk_guard variable. * config/i386/i386.md (UNSPEC_SP_SET, UNSPEC_SP_TEST): Change number. (UNSPEC_SP_TLS_SET, UNSPEC_SP_TLS_TEST): New constants. (stack_protect_set, stack_protect_test): Use *_tls* patterns if TARGET_THREAD_SSP_OFFSET is defined. (stack_tls_protect_set_si, stack_tls_protect_set_di, stack_tls_protect_test_si, stack_tls_protect_test_di): New insns. Revert: 2005-06-27 Richard Henderson <rth@redhat.com> * libgcc-std.ver (GCC_4.1.0): New. * libgcc.h (__stack_chk_guard): Declare.

+
+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
