Can you expand on this? Never heard of it before and can't
find it in gdc --help or manpages.
`--gc-sections` is ld flag that enabled garbage collection of
unreferenced sections in resulting binary. For it to work gcc/gdc
need to be run with `-fdata-sections`and `-ffunction-sections`
placing each symbol into own section. That will, for example,
remove template function bodies that got inlined for all calls.
For template-heavy code with good inliner it can reduce binary
sizes tremendously (running it on snippet from this topic will
reduce gdc binary size to almost match dmd one).
