|
||
|
|
the symbol following the directive. The maximum symbol name length is
|
||
|
|
1023 characters. No relocation is created for this symbol; it will
|
||
|
|
exist purely for pulling in object files from archives. Note that
|
||
|
|
this reloc is not sufficient to prevent garbage collection; use a
|
||
|
|
KEEP() directive in the linker file to preserve such objects.
