Subject: [PATCH] solib-svr4: Avoid unwanted shlib internal BPs When debugging Linux kernel or u-boot with Abatron BDI emulator an error occurs: .. (gdb) tar remote bdi:2001 Remote debugging using bdi:2001 0xeff80050 in ?? () (gdb) mon reset (gdb) cont Continuing. Warning: Cannot insert breakpoint -1. Error accessing memory address 0xc0000000: Unknown error 4294967295.
Date: Fri, 01 Jun 2012 15:01:00 -0000	[thread overview]
Message-ID: <1338562868-22411-1-git-send-email-Joakim.Tjernlund@transmode.se> (raw)

    (gdb) maintenance info breakpoints

    -1      shlib events   keep y   0xc0000000 <_stext> inf 1

gdb mistakenly inserts a special shared library BP even though
there area no such libs in either linux or u-boot.
Fix by testing for ld.so presence.
