BTW alltypes.h is fully emscripten-specific so doesn't need ifdefs/comments like other musl mods. (but I added some anyway to explain things, and because this comment was already added for clock_t). |
This doesn't change the size of the type for wasm32 but helps with wasm64 since it makes these types consistent between the two. Split out from #16922

This brings us back in line with upstream musl. The change to 32-bit was only recently made in #16966. The reason we made this change was made was because we had certain C library calls that were implemented in JS that returned `time_t`. Since returning 64-bit values from JS functions is not always easy (we don't always have WASM_BIGINT available) that simplest solution was to define `time_t` to 32-bit which doesn't have issues at the JS boundary. However, in the intervening time many of the `time_t`-returning function have been moved into native code (See #16606 and #16439) with only two remaining: _mktime_js and _timegm_js. So this change redefines just those two functions to return `int` while keeping `time_t` itself as 64-bit. Fixes: #17393
