sys/i386/i386 db_trace.c
Log:
MFC rev 1.39:
- One can now specify the decimal pid of a process to trace as a parameter.
Since pid's are not in the kernel address space, this doesn't conflict
with the funcionality of specifying an arbitrary frame pointer to the
trace command.
- If the first function of a backtrace maps to fork_trampoline, then this
is a newly fork'd process that has not been executed yet, so just print
out the first frame and then return for that case.
- Lower the default count from 65535 to 1024. ddb doesn't trace into
userland, and if the stack gets hosed and starts looping it's less
annoying.
Partial MFC of rev 1.40:
- Don't try to trace a swapped-out process. (Brought over from NetBSD via
the new alpha trace code.)
