#1 0x1234456765432189 in <signal handler>

[Andrew Cagney]

Hello,

At present a signal handler, in a backtrace is displayed as:

#0  catcher (signal=26) at 
/home/cygnus/cagney/GDB/src/gdb/testsuite/gdb.base/sigaltstack.c:71
#1  <signal handler called>
#2  0x0000000000400751 in thrower (next_level=INNER, sig=26, itimer=1, 
on_stack=134217728) at /home/cygnus/cagney/GD

It isn't exactly informative.  Since we're now expecting GDB to do 
something sane with a signal handlers, I think how it is displayed 
should be changed.  In particular the output should be changed to:

#1  0xffff01111111 in <signal handler>

thoughts?

Andrew
