+Subject: [PATCH] Use ucontext_t not struct ucontext in linux-unwind.h files.
+
+Current glibc no longer gives the ucontext_t type the tag struct
+ucontext, to conform with POSIX namespace rules.  This requires
+various linux-unwind.h files in libgcc, that were previously using
+struct ucontext, to be fixed to use ucontext_t instead.  This is
+similar to the removal of the struct siginfo tag from siginfo_t some
+years ago.
+
+This patch changes those files to use ucontext_t instead.  As the
+standard name that should be unconditionally safe, so this is not
+restricted to architectures supported by glibc, or conditioned on the
+glibc version.
+
+Tested compilation together with current glibc with glibc's
+build-many-glibcs.py.
+
+	* config/aarch64/linux-unwind.h (aarch64_fallback_frame_state),
+	config/alpha/linux-unwind.h (alpha_fallback_frame_state),
+	config/bfin/linux-unwind.h (bfin_fallback_frame_state),
+	config/i386/linux-unwind.h (x86_64_fallback_frame_state,

+	config/tilepro/linux-unwind.h (tile_fallback_frame_state),

+	ucontext_t instead of struct ucontext.

-Subject: [PATCH] sh: Fix building with gcc5/6
-
-Build glibc for sh4-unknown-linux-gnu currently fails if one's
-using GCC5/6: in dl-conflict.c, the elf_machine_rela() function
-is called with NULL as its 3rd argument, sym. The implementation
-of that function in sysdeps/sh/dl-machine.h dereferences that pointer:
-
-const Elf32_Sym *const refsym = sym;
-...
-if (map == &GL(dl_rtld_map))
-  value -= map->l_addr + refsym->st_value + reloc->r_addend;
-
-GCC discovers a null pointer dereference, and in accordance with
--fdelete-null-pointer-checks (which is enabled in -O2) replaces this
-code with a trap - which, as SH does not implement a trap pattern in
-GCC, evaluates to an abort() call. This abort() call pulls many more
-objects from libc_nonshared.a, eventually resulting in link failure
-due to multiple definitions for a number of symbols.
-
-As far as I see, the conditional before this code is always false in
-rtld: _dl_resolve_conflicts() is called with main_map as the first
-argument, not GL(_dl_rtld_map), but since that call is in yet another
-compilation unit, GCC does not know about it. Patch that wraps this
-conditional into !defined RESOLVE_CONFLICT_FIND_MAP attached.
-
-	* sysdeps/sh/dl-machine.h (elf_machine_rela): The condition
-	in R_SH_DIR32 case is always false when inlined from
-	dl-conflict.c. Ifdef out to prevent GCC from insertin an
-	abort() call.
