stepi subcommand for dbx: Run one or more machine instructions
Format
stepi [number]
Description
The stepi subcommand runs instructions of the program. Specify the number of
instructions to be run in the number argument. If the number argument is omitted, it
defaults to 1.
Usage notes
1. The stepi subcommand can be run only while the dbx debug program is
running.
2. If the $hold_next variable is defined, dbx holds all threads except the focus
thread during a stepi subcommand. Then dbx unholds the threads after the
stepi subcommand finishes.
