I should have thought more before speaking actually. I quickly tried it and
realised what your problem is.... you are assuming that the output of the
assembler is something that can be used directly. It is not, it is an
intermediate object file (.o file).
Even though it *seems* easy enough for the assembler to just use a relative
branch, it is still left up to the linker to actually fill in the
relocations.
So once you have linked your program, the disassembly should be what you
expect.
