— The stack frame can also hold local variables or extra arguments and return values. Page 23. 23. The MIPS stack. ▫ In MIPS machines
Local Variables: The next region is for storing the function's local variables. local variable on the stack frame can be calculated using this register and ...
stack as array with index off of stack pointer ... stack in order to hold local variables of h. The activation record (or stack frame) of h is pushed onto the ...
A local variable stack should be memory-resident and be accessed via an offset to a frame pointer register. This arrangement provides excellent support for
Allocation for Local Variables. • Local variables are stored in a stack frame. • Allocation is done by moving the stack pointer %esp subl $4 %esp. • Reference
can have “overlapping” stack frames with our target variable. This is nice and a good point to start but the generated graph suffers from a severe problem

Therefore nothing in this graph overlaps with our target stack-frame. We now inline all subfunction calls in this graph several steps deep (if possible all the
— Caller- and callee-save registers can be put in the stack. — The stack frame can also hold local variables or extra arguments and return values. Page 23
The stack frame technique for dynamic local variable storage in Algol and descendant languages may be adopted in Forth to expand the number of elements easily

Recall: static variables keep their value from one function call to the next gcc Stack Frame Memory local variables High address Low address Stack
The heap stores all objects including all arrays and all class variables (i e those declared "static") The stack stores all local variables including all
functions usually have local variables and parameters - To better store those data for each function call the stack pointer frame pointer and old
