11.4.7

REF_INCLUDE

Allows you to specify sections that you do not want the linker to dead strip, but only if they

satisfy this condition: the file that contains the section must be referenced. This is useful if

you want to include version information from your source file components.

Prototype

REF_INCLUDE{ sectionType [, sectionType]}

11.4.8

SECTIONS

Defines a new section.

Prototype

SECTIONS { section_spec }

where section_spec is in the format:

sectionName : [AT (loadAddress)] {contents} > segmentName

Parameters

sectionName

The name of the section. This name must start with a period character (.), followed by a

consecutive string of alphanumeric and/or underscore characters (_). For example,

.mysection

loadAddress

An optional parameter that specifies the address of the section. The linker sets this to the

relocation address if you do not specify it.

contents

One or more statements that:

●

Assign a value to a symbol. See Section 11.4: Alphabetical keyword listing,

Section 11.3.2: Arithmetic operations, and Section 11.4.1: . (location counter).

●

Describe the placement of an output section, including which input sections are placed

into it. See Section 11.3.6: File selection and Section 11.3.1: Alignment.
