WebAug 2, 2016 · 4. If you can use registers, don’t use memory. A basic rule in assembly language programming is that if you can use a register, don’t use a variable. The register operation is much faster than that of memory. The general purpose registers available in 32-bit are EAX, EBX, ECX, EDX, ESI, and EDI. WebAssembly programmers must understand how these variables work, and how to safely use them. The following program shows the use of memory indirect (pointer) variables. The …

WebSegment Registers. Segments are specific areas defined in a program for containing data, code and stack. There are three main segments −. Code Segment − It contains all the … In computing, a data segment (often denoted .data) is a portion of an object file or the corresponding address space of a program that contains initialized static variables, that is, global variables and static local variables. The size of this segment is determined by the size of the values in the program's source code, and does not change at run time. The data segment is read/write, since the values of variables can be altered at run time. This is …
