I need some help getting started with ignoring initial errors in gdb. Things seem to have changed from what I have in my notes.
From my notes, after:
break Fsignal
r -Q
Below worked:
Breakpoint 3, Fsignal (error_symbol=41328, data="" at eval.c:1471
1471 = (NILP (error_symbol) ? Fcar (data) : error_symbol);
(gdb) p error_symbol
$1 = 41328
(gdb) xsymbol
$2 = (struct Lisp_Symbol *) 0xc85aa0 <lispsym+41328>
"scan-error"
(gdb) condition 3 error_symbol!=41328
(gdb) c
But now, I am getting this breakpoint:
Starting program: /home/kmodi/downloads/git/emacs/src/emacs -Q

So, what would be the right way to ignore that hex error_symbol code? Earlier that code was in decimal. But now it is in hex.
As seen above, none of the below works:
- condition 3 error_symbol!=XIL(0xd980) -- What is XIL?
- condition 3 error_symbol!=0xd980
- condition 3 error_symbol!=55680
Thanks.
