Is anyone succesfully using gdb for mipsel to debugIt appears to work for me. My gdb has a ton of patches from Amit Kale though. The kernel is the latest malta with a couple of patches that shouldn't affect gdb.
core dumps? If so, can you share your secrets for
success? I tried various recent versions (6.3,
6.1.1), but backtrace never works right, even though
the stack pointer appears to be valid. gdb-5.3
partially works, but not completely.
Forcing gdb to use a specific stack pointer and PC
(frame <sp> <pc>) doesn't seem to help either.
Using linux 2.4.25 and gcc 3.3.3.
