In the BNF definitions in this section, line returns and spaces have been added to improve readability. They are not required in the scatter-loading definition and are ignored if present in the file.
A scatter_description is defined as one
or more patterns:load_region_description
Scatter_description ::=
load_region_description+
A is
defined as a load region name, optionally followed by attributes
or size specifiers, and one or more execution region descriptions:load_region_description
load_region_description ::=
load_region_name (base_address | ("+" offset)) [attributes] [max_size]
"{"
execution_region_description+
"}"
An is
defined as an execution region name, a base address specification,
optionally followed by attributes or size specifiers, and one or more
input section descriptions:execution_region_description
execution_region_description ::=
exec_region_name (base_address | "+" offset) [attribute_list] [max_size | "–" length]
"{"
input_section_description*
"}"
An is
defined as a source module selector pattern optionally followed
by input section selectors:input_section_description
input_section_description ::=
module_select_pattern
["("
("+" input_section_attr | input_section_pattern | input_symbol_pattern)
("," "+" input_section_attr | "," input_section_pattern | "," input_symbol_pattern)*
")"]
Figure 5.5 shows the contents and organization of a typical scatter-loading description file.
