Re: RFC and PATCH - Defining variables in the linker script withoutdefining them as symbols on the file

Hi Ian,

Because it was never programmed not to.  There is no good reason to
accept this, and in fact I agree that the parser ought to issue an
error message.  It is just that I doubt if anyone has ever done this
with a linker script before.


Note that there is a very good reason to accept
    foo = bar
if bar is defined in some .o file.

Oh indeed - I meant that an error should be produced only when bar is not defined anywhere.

I don't think you can report an error in the parser.

Which is presumably why the undefined symbol is created in the first place. Hmm, I guess that we have to live with this behaviour, so the right thing to do would be to document it, yes ?

Cheers
  Nick
