Relies on putting break +instructions on breakpoints and step targets- normal stuff, and does not +employ hardware breakpoint support at this time. As written, a single +breakpoint in a loop will not be reasserted unless the user steps or has +a 2nd one, since breakpoints are only reset when the gdb stub is +re-entered. A useful enhancement would be to fix the break instruction +management so the stub could invisibly put a 2nd break after the 1st +"official" one so it can silently reset breakpoints. Shouldn't be too +hard, mostly a matter of working it out. + +This was tested only against an R3000 MIPS. It should work OK on a +R4000. Needs to be tested at some point. + +This stub supports threads as implemented by gdb 5 and doesn't have any +bugs I'm aware of. + +Greg Menke +3/5/2002 + +/*****************************************************/ + The contents of this directory are based upon the "r46kstub.tar.gz" package released to the net by |
