TotalView Users Guide - CI Wiki

STACK FRAME: Whenever your program calls a function, it creates a set of
information that includes the local variables, arguments, contents of the
registers used by an individual routine, a frame pointer pointing to the previous
stack frame, and the value of the program counter (PC) at the time
the routine was called. The information for one function is called a “stack
frame” as it is placed on your program’s stack.
When your program begins executing, it has only one frame: the one allocated
for function main(). As your program calls functions, new frames are
allocated. When a function returns to the function from which it is called,
the frame is deallocated.
STACK POINTER: A pointer to the area of memory where subprocedure arguments,
return addresses, and similar information is stored. This is also
called a frame pointer.
STACK TRACE: A sequential list of each currently active routine called by a
program, and the frame pointer that points to its stack frame.
STATIC (SYMBOL) SCOPE: A region of a program’s source code that has a set
of symbols associated with it. A scope can be nested inside another scope.
STEPPING: Advancing program execution by fixed increments, such as by
source code statements.
STL: An acronym for Standard Template Library.
STOP SET: A set of threads that TotalView stops after an action point
triggers.
STOPPED/HELD STATE: The state of a process whose execution has paused
in such a way that another program event (for example, arrival of other
threads at the same barrier) is required before it is capable of continuing
execution.
STOPPED/RUNNABLE STATE: The state of a process whose execution has
been paused (for example, when a breakpoint triggered or due to some
user command) but can continue executing as soon as a resume command
is issued.
STOPPED STATE: The state of a process that is no longer executing, but will
eventually execute again. This is subdivided into stopped/runnable and
stopped/held.
STRIDE: The interval between array elements in a slice and the order in
which TotalView displays these elements. If the stride is 1, TotalView displays
every element between the lower bound and upper bound of the
slice. If the stride is 2, TotalView displays every other element. If the stride
is –1, TotalView displays every element between the upper bound and lower
bound (reverse order).
SYMBOL: Entities within program state, machine state, or debugger state.
SYMBOL LOOKUP: Process whereby TotalView consults its debugging information
to discover what entity a symbol name refers to. Search starts with
a particular static scope and occurs recursively so that contains scopes are
searched in an outward progression.
