- Subject: [Patch]: Add objdump -P for Mach-O
Hi,
there are many details displayed currently by 'objdump -p' on Mach-O files, and I plan to add more.
In order to make this feature more useful, I propose to move to the '-P' form, so that users can easily display only a part of that.
Ok for trunk ?
Tristan.
