Three bug fixes suggested by community member dednev@rambler.ru:
*elf*-microblaze-relaxation.patch short description:
The roots of invalid data offsets (pointer) after relaxation are in
internal symbol table cache handling. If symbol table was cached while
section processing for garbage collection, the elf_tdata
(abfd)->symtab_hdr pointer is not NULL, but (Elf_Internal_Sym *)
symtab_hdr->contents array contains data for local symbols only. But in
the repeated relocation processing there is no check whenever the symbol
index is local (ELF32_R_SYM (irelscan->r_info) < symtab_hdr->sh_info) or
global. This leads to the buffer overflow (global symbol index is out of
bounds) and following invalid relocation processing, especially in extra
relocation data modifications (f.e. irelscan->r_addend could be
decreased by arbitrary values).
*elf*-microblaze-no-keep-memory.patch short description:
There is incorrect newly allocated buffers handling if internal memory
caching is disabled (without --no-keep-memory ld switch). This leads to
possible double free(...) calls for such data and results in unexpected
ld termination with abort(). I've fixed this issue by implementing
similar to the elf32-avr.c data buffer handling.
*elf*-imm-check-for-relaxation.patch short description:
I've reverted Xilinx path to the original GNU binutils bfd code for
microblaze, because this patch incorrectly leaves some "imm -1"
instructions in resulting binary file after relaxation and increases
executable size. If you look at the IMM instruction argument processing
in binutils/gas/config/tc-microblaze.c you will see, that gas checks are
similar to the original bfd microblaze_elf_relax_section(...)

This is the result of automated script (0.9.0) conversion:
oe-core/scripts/contrib/convert-overrides.py .
converting the metadata to use ":" as the override character instead of "_".

Target gdb/gdbserver failed to compile due to out of date
microblaze-linux-nat.c, correct this and ancillary files. Note, this only
corrects compilation the code may not function properly.

Resync the microblaze toolchain items to match the latest YP master version.
binutils and gdb are based on the same patch set, but the release version
are based on slightly different sources, thus the patches are a bit
different.
