+
+	PR c++/71696
+	* cplus-dem.c: Prevent infinite recursion when there is a cycle
+	in the referencing of remembered mangled types.
+	(work_stuff): New stack to keep track of the remembered mangled
+	types that are currently being processed.

+	remembered type onto the stack.
+	(pop_processed_type): New method to pop currently processed
+	remembered type from the stack.
+	(work_stuff_copy_to_from): Copy values of new variables.
+	(delete_non_B_K_work_stuff): Free stack memory.
+	(demangle_args): Push/Pop currently processed remembered type.
+	(do_type): Do not demangle a cyclic reference and push/pop
+	referenced remembered type.
+
+cherry-picked from commit of

+Subject: [PATCH 40/49] Add ssp_nonshared to link commandline for musl targets
+
+when -fstack-protector options are enabled we need to
+link with ssp_shared on musl since it does not provide
+the __stack_chk_fail_local() so essentially it provides
+libssp but not libssp_nonshared something like
+TARGET_LIBC_PROVIDES_SSP_BUT_NOT_SSP_NONSHARED
+ where-as for glibc the needed symbols
+are already present in libc_nonshared library therefore
+we do not need any library helper on glibc based systems
+but musl needs the libssp_noshared from gcc

+Backport and edit of patches from:
+https://gcc.gnu.org/viewcvs/gcc?limit_changes=0&view=revision&revision=249957
+by jsm28 (Joseph Myers)
+
+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.
