Re: [cc65] Request for feature: Compression of RODATA Segment

The RODATA size savings would have to be at least as much as the size
of the decompression code needed to expand it to be worthwhile. Also,
of course, your target platform has to have RAM to put the RODATA
segment into.

If your platform is one that loads the entire program into RAM anyway,
why not just compress the whole program and add a decompressing stub.
There are utilites that did this on a lot of platforms, turning a
binary executable into a smaller one. If you can find such a utility
it would probably do a better job of making your binary smaller (and
be simpler to use) than trying to compress only the RODATA
automatically as a linker step.
