Hi all,
I have a gdb stub,running on my target.
I am able to connect to the target through TCP and debug
my debug from the host.
My Problem is
1. I get a SIGTRAP received message for every function call,
even if I am not stepping into the function or have not set a breakpoint
in
the function.
I get the SRC_AND_LOC message always,when ideally I should only the
the SRC_LINE displayed.
eg: When I step through a function foo() in function xyz() I get
xyx () at xyz.c:78
2. Also when a breakpoint is hit ,The don't get the Breakpoint number
displayed.
I get the SRC_AND_LOC displayed,but no breakpoint info.
What could be the problem.
I am using gdb 6.0 configured for i386-elf on cygwin
Could anything be possibily wrong with my gdb stub,which is
derived from the basic gdb stub.
Thanks
Kiran

That certainly doesn't sound like normal behavior.
But unless we can reproduce the problem ourselves, we can't do much
about it. I suspect there's some problem with your stub. When you
say "set debug remote 1", does it seem to be doing all the right things?

hi all,
i was going through the GDB support for
tracepoints and the packets it sends to the stub.i
thought of collecting the registers on the gdbserver
side using a single ptrace to collect all the
registers and then store the ones requested instead of
a ptrace for each register. the problem i now face is
: there are 3 different ptrace requests for collecting
registers,viz,PTRACE_GETREGS, PTRACE_GETFPREGS and
PTRACE_GETFPAREGS.how do i determine (on the stub
side) which of these to call as i don't have anything
on the GDBSERVER side (or so i guess) which would
categorize a register to an integer or a float
register.
also,please suggest if there is a better way in
which i can accomplish the above(i.e.,implementation
of collecting registers in a better way).
thanks in advance,
ankit.
