[RFC] [PATCH] ld: Add --no-print-map-discarded option

[fshahbazker@wavecomp.com]

Hi,

This patch introduces an option to disable the listing of discarded sections
in map file output. The use case stems from a largeish application built with
-ffunction-sections & --gc-sections where the list of discarded sections
blows up the map file output. The default behaviour will ofcourse remain
to print discarded sections, but the new option would allow us to disable it.

Comments welcome.

Regards,
Faraz Shahbazker
