Normally, the linker will place files and sections matched by wildcards
|
||||
in the order in which they are seen during the link. You can change
|
||||
this by using the @code{SORT} keyword, which appears before a wildcard
|
||||
pattern in parentheses (e.g., @code{SORT(.text*)}). When the
|
||||
@code{SORT} keyword is used, the linker will sort the files or sections
|
||||
this by using the @code{SORT_BY_NAME} keyword, which appears before a wildcard
|
||||
pattern in parentheses (e.g., @code{SORT_BY_NAME(.text*)}). When the
|
||||
@code{SORT_BY_NAME} keyword is used, the linker will sort the files or sections

into ascending order by name before placing them in the output file.

@code{SORT_BY_ALIGNMENT} is very similar to @code{SORT_BY_NAME}. The
