Just a small note:
-CX -XX are not needed for the top-tier targets nowadays. The section
based smart linking is a default option in recent FPC versions.
At least -XX is still necessary, otherwise we don't enable dead
code/data stripping in the linker (at least not on Linux). And on macOS,
-CX is also needed, otherwise the compiler does not emit a directive in
the object files that dead code/data stripping should be enabled based
on whether or not there are references to the global symbols preceding them.
Yes, you are right. On Windows, since introduction of the internal linker long time ago, both -CX -XX are ignored and
smart linking is always ON. I've supposed that this is also true for any target which supports tf_smartlink_sections and
these options are only needed for older smart linking method which involves generation of static libraries containing
tons of object files.
Neither parameter may be necessary on Windows, but that's probably the
only one.
Android and MS-DOS targets also ignore -CX -XX
