What I meant was that the EABI specifies that a section without mapping 
symbols should be treated as if it contained data, regardless of any 
attributes that might apply to that section.  (I think that this is 
correct, I do not actually have the text of the EABI in front of me).

But for arm-elf binaries, or arm-wince, or arm-pe, the EABI is not being 
used and in these cases it would make intuitive sense that sections 
without mapping symbols but with a contains-executable-code attribute of 
some kind should be treated as if they contained code.

Does this make sense ?
