I discovered a new feature:
(top-gdb) set prompt-escape-char 0x25
(top-gdb) set prompt PC=0x%0x%$pc
PC=0x1802f68
Perhaps it could be change do use the printf code vis:
set prompt "0x%x ", $pc
Anyway, Michael, was there any doco on this? I can't find anything.
No, I think I was hoping no one would use it. ;-)
This was something that a customer forced us to add, back in the
"bad old days" when there wasn't much review over gdb. I really really tried to talk them out of it, honest.
