you’ll be aware of things like cpu registers, and the call stack — these resources have to be managed in order for a program to work (and in other languages, these resources are automatically managed for us. there are no structured statements in assembly language — so, all flow of control constructs have to be programmed in an “if-goto” style (in other languages, the compiler translates structured statements into if-goto. adding, removing instructions) — a branch instruction that uses a label as the target accomodates changes in the count of how many instructions are to be conditionally skipped. to select register, we need a mental model of which registers are busy and which are free.
however, with one cpu there are limited and fixed number of registers (such as 32 or 16), and, all the functions have to share these registers!! for example, to the hardware, most registers are equivalent, even though the registers are partitioned or assigned particular uses by the software conventions. volatile registers are free to be used by any function without concern for the previous usage of or values in that register. thus, these registers are used for variables and temporaries that do not need to span a function call. i’ll be retiring one of these years so perhaps i’ll touch bases with you to see if i can get back into it.
