Question

Which are the advantages of intermediate re in assembler?

Answer 1

1.Sometimes it’s the only way to access the functions you need - say when writing device drivers or o/s code that directly access hardware.

2.Tightly coded assembly code can provide better performance for time-critical and/or resource-intensive activities.

3.For embedded, real-time applications, one sometimes writes code to run directly on bare iron (i.e., no operating system) - particularly when using single-chip micro-controllers with limited memory. Tightly coded assembler can use less memory.
