Nathan Sidwell <nathan@codesourcery.com> * gdb.texinfo (GDB/MI Tracepoint Commands): Add notes about the GDBN equivalent. (Set Tracepoints): Remove mention that conditional tracepoints don't exist. (Tracepoint Actions): Clarify when while-stepping collection happens, note that while-stepping does not automatically collect $pc.
