Alphabetical keyword listing

Table 11 lists all the functions, keywords, directives, and commands that linker command

files can include.

11.4.1

(location counter)

The period character (.) always maintains the current position of the output location. Since

the period always refers to a location in a SECTIONS block, it cannot be used outside a

section definition.

can appear anywhere a symbol is allowed. Assigning a value to . that is greater than its

current value causes the location counter to move, but the location counter can never be

decremented.

This keyword can be used to create empty space in an output section. In the example that

follows, the location counter is moved to a position that is 0x10000 bytes past the symbol

__start

Example 19 Moving the location counter

.data :

{

*.(data)

*.(bss)

*.(COMMON)

__start = .;

. = __start + 0x10000;
