-Subject: [PATCH] gcc: xtensa: don't force PIC for uclinux target
-
-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.
