Re: GDB single-step fails on alpha (Re: CVS commit: src/share/mk)



Not sure if related and relevant, but I noted that OpenBSD defines
FIX_SSTEP for alpha.

#ifdef _KERNEL
# define FIX_SSTEP(p)	process_sstep(p, 0)
#endif

--- sys/arch/alpha/include/ptrace.h

and additional logic in process_sstep()

 * process_sstep(proc)
 *	Arrange for the process to trap after executing a single instruction.

-- sys/arch/alpha/alpha/process_machdep.c
