Description Richard Henderson 2009-11-14 17:37:37 UTC 
The output of -Map is produced at the end of linking,
and is *not* produced if relocation errors occur.

This lack of map file can make it very difficult to
understand why a relocation was out of range.

Hi Richard,

  Something like the uploaded patch perhaps ?

Cheers

Wrong PR, Nick.

And that 150 thing is *really* gross.  Wouldn't it be
better to change command_line.relax to be a tri-state
thingy, so that the backend can tell if it's unset?

Hi Richard,

Doh!  Bogus patch obsoleted.

I'll rework the patch as you suggested and upload it to the proper PR.

Cheers
  Nick

Map output can't be produced until late in linking.  --noinhibit-exec helps in some cases.
