+	* 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

+Subject: [PATCH] boehm-gc: check for execinfo.h directly
+
+The current header depends on glibc version checks to determine whether
+execinfo.h exists which breaks uClibc.  Instead, add an explicit configure
+check for it.
+
[phone]  Mike Frysinger  <vapier@g.o>
+
+	* configure.ac: Call AC_CHECK_HEADERS([execinfo.h]).
+	* configure: Regenerated.
+	* include/gc.h [HAVE_EXECINFO_H]: Define GC_HAVE_BUILTIN_BACKTRACE.
+	* include/gc_config.h.in: Regenerated.

+Subject: [PATCH] libjava: fix locale handling when sorting JNI methods
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When building under LANG=cs_CZ.UTF-8, the JNI method check fails:
+
+/bin/bash ../../scripts/check_jni_methods.sh
+Found a problem with the JNI methods declared and implemented.
+(<) missing in implementation, (>) missing in header files
+> Java_gnu_java_awt_peer_gtk_GtkClipboard_advertiseContent
+> Java_gnu_java_awt_peer_gtk_GtkClipboard_initNativeState
+... lots more ...
+
+While the sed commands are run under LC_ALL=C, the two sort commands are
+not, and they end up producing unexpected output (for the test).  Once we
+run both under LC_ALL=C, the check passes.  While we're here, we can also
+combine latter the `sort|uniq` into `sort -u` to match the earlier code.

+The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
+you have to actually list out the multilibs you want or you will end up with
+just one when using targets like 'sh4-linux-gnu'.

+The resulting toolchain can't even build a kernel as the kernel needs to build
+with the nofpu flag to be sure that no fpu ops are generated.

+Here we restore the gcc-3.x behavior; the additional overhead of building all

+This fixes bootstrap of GCC with BOOT_CFLAGS="-g -O2 -fgraphite-identity
+-floop-nest-optimize -floop-block -floop-interchange -floop-strip-mine".  It
+passes regstrap on amd64-linux.  A previous change
+(https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=213816), replaced
+isl_int with isl_val because isl_int would be deprecated. Since isl_val has
+stricter checks, it exposed the bug.  In the test case (isl_set_max_val) would
+return infinity which would remain unchecked.  We now check if the value
+returned is an integer or not, and bail out if it isn't.  The other problem was
+that we were allowing all kinds of data-refs in a scop.  Now we discard a scop
+if it has any date-ref other than (ARRAY_REF, MEM_REF, COMPONENT_REF).
+
+	PR middle-end/61929
+	* graphite-dependences.c (add_pdr_constraints): Renamed
+	pdr->extent to pdr->subscript_sizes.
+	* graphite-interchange.c (build_linearized_memory_access): Add
+	back all gcc_assert's that the "isl_int to isl_val conversion"
+	patch has removed.  Refactored.
+	(pdr_stride_in_loop): Renamed pdr->extent to pdr->subscript_sizes.
+	* graphite-poly.c (new_poly_dr): Same.
+	(free_poly_dr): Same.
+	* graphite-poly.h (struct poly_dr): Same.
+	* graphite-scop-detection.c (stmt_has_simple_data_refs_p): Ignore
+	all data references other than ARRAY_REF, MEM_REF, and COMPONENT_REF.
+	* graphite-scop-detection.h: Fix space.
+	* graphite-sese-to-poly.c (build_pbb_scattering_polyhedrons): Add
+	back all gcc_assert's removed by a previous patch.
+	(wrap): Remove the_isl_ctx global variable that the same patch has
+	added.
+	(build_loop_iteration_domains): Same.
+	(add_param_constraints): Same.
+	(pdr_add_data_dimensions): Same.  Refactored.
+	(build_poly_dr): Renamed extent to subscript_sizes.

+dlopen cloog-isl library rather than link to it directly.  This prevents
+cloog upgrades that change the soname from breaking the compiler.
+
+http://pkgs.fedoraproject.org/cgit/gcc.git/tree/gcc5-isl-dl.patch
+
+In FreeBSD dlopen is part of libc so we can't just hardcode -ldl.
+We abuse the existing plugin check logic to pull out that info.

+extended by Gentoo to support isl-0.15

+	* gimplify.c (struct gimplify_ctx): Turn boolean fields into 1-bit
+	fields, add keep_stack and reorder them.
+	(gimplify_bind_expr): Save gimplify_ctxp->keep_stack on entry then
+	set it to false.  Do not insert a stack save/restore pair if it has
+	been set to true by the gimplification of the statements.
+	Restore it to the saved value on exit if it is still false.
+	(gimplify_vla_decl): Do not set gimplify_ctxp->save_stack here.
+	(gimplify_call_expr) <BUILT_IN_ALLOCA[_WITH_ALIGN]>: New case.  Set
+	either save_stack or keep_stack depending on CALL_ALLOCA_FOR_VAR_P.
+	* doc/extend.texi (Variable Length): Document new behavior.
+	* doc/generic.texi (Blocks): Document new handling of VLAs.

+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, Mike Frysinger 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.
+
+Thank you all:
