Linker Command Line Linking Files

3–10 UM004001-COR1103

Linker Command RANGE

This command sets the lower and upper limits of a control section or an address space. The

linker issues a warning message if an address falls beyond the range declared with this com

mand.

The linker provides multiple ways for the user to apply this command for a link session. Each

separate case of the possible syntax is described below.

CASE 1

Syntax : RANGE <name> <expression> , <length> [ , ... ]

<name> may be a control section, or an address space. The first <expression> indicates the

lower bound for the given address RANGE. The <length> is the length, in words, of the

object.

Example: RANGE ROM %700 , %100

CASE 2

Syntax :RANGE <name> <expression> : <expression> [ , ... ]

<name> may be a control section or an address space. The first <expression> indicates the

lower bound for the given address RANGE. The second <expression> is the upper bound for

it.

Example: RANGE ROM %17ff : %2000

NOTE: Refer to the Expression Formats for the format of writing an expression.

LINKER COMMAND LINE

The syntax for the linker command line is:

ZLD [<options>]<filename1> ...<filenamen>.

• The “[ ]” enclosing the string “options” denotes that the options are not mandatory. In

this document this convention is continued for further discussion on linker’s syntax and

operations.

• The items enclosed in “< >” indicate the non-literal items.

• The “. . .” (ellipses) indicate that multiple tokens can be specified. These tokens are of

the type of the non-literal specified in the syntax just prior to the ellipses.

• The syntax uses “%” prefix to a number to specify a hexadecimal numeric

representation.

• The linker links the files listed in <filename> list. Each <filename> is the name of a

COFF object file or library file, or the name of a text file containing linker commands

and options.
