dnexti
Steps machine instructions, stepping over subroutines
Format
dnexti [-back ] [ num-steps ]
Arguments
-back
(ReplayEngine only) Steps a machine instruction back to the previous instruction, stepping over subroutines. This option can be abbreviated to -b.
num-steps
An integer greater than 0, indicating the number of instructions to be executed.
Description
The dnexti command executes machine-level instructions; that is, it advances the program by a single instruction. However, if the instruction invokes a subfunction, the dnexti command executes the subfunction as if it were one instruction; that is, it steps over the call. This command steps the thread of interest (TOI) while allowing other threads in the process to run.
The optional num-steps argument defines how many dnexti operations to perform. If you do not specify num-steps, the default is 1.
The dnexti command iterates over the arenas in the focus set, performing a thread-level, process-level, or group-level step in each arena, depending on the width of the arena. The default width is process (p).
