[Qemu-devel] [RFC PATCH 0/3] Tweaks to linux-user -dfilter

Posted by Alex Bennée 7 years, 2 months ago

Hi,

While debugging a dynamically linked program I got frustrated having
to manually calculate the .text segment to avoid the logs getting
filled up with library stuff I wasn't really interested in. This
allows us to:

  - have multiple -dfilter lines for flexibility
  - specify -dfilter progtext as a shortcut

We could potentially extend this to handle -dfilter lib at a later
date.

Thoughts?

Alex Bennée (3):
  util/log: allow -dfilter to stack
  util/log: add qemu_dfilter_append_range()
  linux-user: add -dfilter progtext shortcut
