+
+	* gcc/gcc.c (main): Add support for external spec file via the GCC_SPECS env var
+	and move the process of the user specifed specs.
+
+	This allows us to easily control pie/ssp defaults with gcc-config profiles.
+	Original patch by Rob Holland
+	Extended to support multiple entries separated by ':' by Kevin F. Quinn
+	Modified to use getenv instead of poisoned GET_ENVIRONMENT by Ryan Hill
+	Modified to process the GCC_SPECS env var befor DRIVER_SELF_SPECS by Magnus Granberg

+Ensure that msgfmt doesn't encounter problems during gcc bootstrapping.

+
+msgfmt: /var/tmp/portage/sys-devel/gcc-4.1.2/work/build/./gcc/libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/libstdc++.so.6)
+
+The libgcc_s.so used during build doesn't satisfy the needs of the
+libstdc++.so that msgfmt is linked against. On the other hand, msgfmt
+is used as a stand-alone application here, and what library it uses
+behind the scenes is of no concern to the gcc build process.
+Therefore, simply invoking it "as usual", i.e. without any special
+library path, will make it work as expected here.

+Set the default behavior on alpha to use -mieee since the large majority of

+it).
+
+To satisfy those people who may not want -mieee forced on them all the time,
+we also provide -mno-ieee.
+
+Patch by Mike Frysinger <vapier@gentoo.org>
+
+Note: upstream doesn't want to take this due to long standing behavior, and
+because it'd make behavior across OS's inconsistent:
+	https://gcc.gnu.org/ml/gcc-patches/2003-07/msg02144.html
+
+This makes sense for upstream, but Gentoo is more concerned about packages
+behaving the same across arches under Linux.

+	PR target/65689
+	* genpreds.c (struct constraint_data): Add maybe_allows_reg and
+	maybe_allows_mem bitfields.
+	(maybe_allows_none_start, maybe_allows_none_end,
+	maybe_allows_reg_start, maybe_allows_reg_end, maybe_allows_mem_start,
+	maybe_allows_mem_end): New variables.
+	(compute_maybe_allows): New function.
+	(add_constraint): Use it to initialize maybe_allows_reg and
+	maybe_allows_mem fields.
+	(choose_enum_order): Sort the non-is_register/is_const_int/is_memory/
+	is_address constraints such that those that allow neither mem nor
+	reg come first, then those that only allow reg but not mem, then
+	those that only allow mem but not reg, then the rest.
+	(write_allows_reg_mem_function): New function.
+	(write_tm_preds_h): Call it.
+	* stmt.c (parse_output_constraint, parse_input_constraint): Use
+	the generated insn_extra_constraint_allows_reg_mem function
+	instead of always setting *allows_reg = true; *allows_mem = true;
+	for unknown extra constraints.
+
+	* gcc.target/aarch64/c-output-template-4.c: New test.

+This work started with bugs #94325 #100689 #106222 #149292 #149649 and the overlay on http://overlays.gentoo.org/dev/kevquinn.
+By Kevin K. Quinn, Peter S. Mazinger, Natanael Copa, Alexander Gabert, Solar, PaX Team, SpanKY and mentor.
+
+The work stalled. Some threads on the Gentoo forum started to do their own fixes to get it working.
+Xake started the thread where most of the new work was done: "How long until hardened and toolchain will produce a hardened gcc4?"
+http://forums.gentoo.org/viewtopic-t-668885.html. I joined the thread and started to code.
+
+We started with the pieworld code from kevquinn's overlay. The PIE and minispecs part hit the tree later on.
+With GCC 4.4.0 I was willing to do some code cleanup, use built-in specs and add it as --enable-esp in the
+configure command line. On GCC 4.8.0 we use DRIVER_SELF_SPECS for the specs.
+From Gcc 4.9.0 it will have -fstack-protector-strong on as default.
+
