Re: GDB bug: target.c (target_signal_from_host): unrecognized real -time signal on arm

[todd dot kallam at acterna dot com]

Hi,

I have had the same problem with each of the following versions:

   insight+dejagnu-5.2.0_20020624.tar.bz2
   gdb+dejagnu-weekly-CVS-5.2.0_20020618.tar.bz2
   gdb-5.2.tar.gz

I configure gdb with the following command:

     ./configure --target=arm-linux

I configured gdbserver with the following command:

   ./configure arm-linux

The following insight+dejagnu-5.2.0_20020624.tar.bz2 code in
gdb/signals/signals.c reports the problem:

#if defined (SIGRTMIN)
  if (hostsig >= SIGRTMIN && hostsig <= SIGRTMAX)
    {
      /* This block of TARGET_SIGNAL_REALTIME value is in order.  */
      if (33 <= hostsig && hostsig <= 63)
     return (enum target_signal)
       (hostsig - 33 + (int) TARGET_SIGNAL_REALTIME_33);
      else if (hostsig == 64)
     return TARGET_SIGNAL_REALTIME_64;
      else
     error ("GDB bug: target.c (target_signal_from_host): unrecognized real-time
 signal");
    }
#endif

Regards,

Todd

I committed a fix for this problem at the same time I committed the
multithread support.  Could you be more specific about which snapshot
you are using?
