Hi,

Do you know of any situation where gdb used PTRACE_SINGLEBLOCK?
I found no reference on the current GDB, but there were any branches or older versions using it ?
I'm asking because I saw some references to gdb using PTRACE_SINGLEBLOCK in some linux-devel mailing lists.

Is this a request that has been implemented recently to single-stepbasic blocks (branch-to-branch)? I seem to recall ppc kernel hadsomething like this.
