-
-xtensa-uclinux uses bFLT executable file format that cannot relocate
-fields representing offsets from data to code. C++ objects built as PIC
-use offsets to encode FDE structures. As a result C++ exception handling
-doesn't work correctly on xtensa-uclinux. Don't use PIC by default on
-xtensa-uclinux.

-space. In windowed ABI register spill area for the previous call frame

-Subject: [PATCH] Make MicroBlaze support DWARF EH (old Xilinx patch, needed
- for glibc build).
-
-This patch, taken from
-<https://git.busybox.net/buildroot/tree/package/gcc/5.4.0/840-microblaze-enable-dwarf-eh-support.patch>
-and with a few formatting cleanups and an update for the removal of
-gen_rtx_raw_REG, enables DWARF EH support for MicroBlaze.
-
-This is needed for building glibc with a compiler that includes shared
-libgcc; right now all glibc builds for MicroBlaze are failing with my
-bot for lack of this support. (It's dubious if we should have glibc
-ports at all where required support is missing in FSF GCC.)
-
-Tested building glibc with build-many-glibcs.py. I have *not* done
-any other testing or any execution testing for MicroBlaze.

-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.

+xtensa-uclinux uses bFLT executable file format that cannot relocate
+fields representing offsets from data to code. C++ objects built as PIC
+use offsets to encode FDE structures. As a result C++ exception handling
+doesn't work correctly on xtensa-uclinux. Don't use PIC by default on
+xtensa-uclinux.

+Subject: [PATCH] Make MicroBlaze support DWARF EH (old Xilinx patch, needed
+ for glibc build).
+
+This patch, taken from
+<https://git.busybox.net/buildroot/tree/package/gcc/5.4.0/840-microblaze-enable-dwarf-eh-support.patch>
+and with a few formatting cleanups and an update for the removal of
+gen_rtx_raw_REG, enables DWARF EH support for MicroBlaze.
+
+This is needed for building glibc with a compiler that includes shared
+libgcc; right now all glibc builds for MicroBlaze are failing with my
+bot for lack of this support. (It's dubious if we should have glibc
+ports at all where required support is missing in FSF GCC.)
+
+Tested building glibc with build-many-glibcs.py. I have *not* done
+any other testing or any execution testing for MicroBlaze.
