Re: [Simulavr-devel] Error during debug with gdb

[Klaus Rudolph]

Hi Bret,

which versions of tools do you use? gdb, ddd? simulavr or simulavrxx? 
from cvs or last tgz?

At first, the simulator deals not with dwarf. It simple read and write 
memory or regiserts from gdb.
Any interpretation for debug information is handled in gdb or other 
tools above gdb.
After getting some more informations from your side I maybe can try to 
reproduce the problem if
you are using simulavrxx cvs source and newest gdb version.
what do you mean with "a p i" command?

Bye
  Klaus
