[PATCH 0/5] arm: set of big endian related fixes for armeb (v7)

[Victor Kamensky]

Hi Folks,

Please find five patches following this cover letter that address several
big endian related issues for ARM V7 target. Problems were discovered by
running gdb/testsuite on armeb (big endian) target rootfs/kernel and 
comparing results from the same source against arm (little endian).

Note there are several failures remain that are not addressed by this 
series. I.e valgrind related test cases all failed, because valgrind does 
not support armeb target. There are other failures in a bit obscure
places like gdb.dwarf2/implptrpiece.exp, gdb.python/py-value-cc.exp,
but over all number of passes/failures significantly improved in armeb
case. 

Please note it is my first attempt to contribute into gdb. If I missed
something please guide me how I can correct that.

Thanks,
Victor

  ARM: plt_size functions need to read instructions in right byte order
  ARM: extract_arm_insn function need to read instrs correctly in be8
    case
  ARM: arm_breakpoint should be little endian form in case for arm BE8
  ARM: read_pieced_value do big endian processing only in case of valid
    gdb_regnum
  ARM: asm-source.exp link options in case of armv7b target
