dynlib keeps exported functions alive in emscripten (#23469)
ref https://forum.nim-lang.org/t/11338

`EMSCRIPTEN_KEEPALIVE` is a macro that is used to prevent unused
functions from being deadcode eliminated in emscripten, which is a
simple wrapper around `__attribute__((used))`. This PR follows suits and
expects dynlib is supposed to keep these functions alive. In the future,
`exportwasm` might be introduced.
After this PR, a function with `{.dynlib, exportc.}` can be reused from
other wasm programs reliably.Diffstat (limited to 'compiler/modulepaths.nim')
