Subject: [PATCH] remote: Avoid unwanted shlib internal BPs When debugging Linux kernel or u-boot with Abatron BDI emulator an error occurs:
Date: Fri, 01 Jun 2012 13:37:00 -0000	[thread overview]
Message-ID: <1338557804-20910-1-git-send-email-Joakim.Tjernlund@transmode.se> (raw)

Continuing.
Warning:

gdb mistakenly inserts a special shared library BP even though
there area no such libs in either linux or u-boot.

Fix this by explicitly informing remote_add_inferior() that
the remote is attached.
