Types of section-related symbols
The linker generates different types of section-related symbols for output and input sections.
The types of symbols are:
Image symbols, if you do not use scatter-loading to create a simple image. A simple image has up to four output sections (XO, RO, RW, and ZI) that produce the corresponding execution regions.
Input section symbols, for every input section present in the image.
The linker sorts sections within an execution region first by attribute RO,
RW, or ZI, then by name. So, for example, all
sections are placed in one contiguous block. A contiguous block of sections with
attribute and name is known as a consolidated section.
