[RFC] Why does ui_out_field_core_addr pad with leading zeroes?


Hi.

I couldn't find an explanation of *why* ui_out_field_core_addr pads
the address with leading zeroes.

Does anyone know?

2010-03-18  Doug Evans  <dje@google.com>

	* ui-out.c (ui_out_field_core_addr): Don't pad address with leading
	zeroes.
