sunfish added a comment. Do we still intend to unify Emscripten's ABI with wasm32-unknown-unknown or wasm32-wasi eventually? This is talking a step away from that.
One of the assumptions behind this is that it would be ok for malloc to be 16-byte aligned anyway, because SIMD use cases benefit from being able to call `malloc` and get a buffer aligned for SIMD. Do we have more information on how much this matters in practice? Another observation is that part of the reason for long double being 128-bit is to leave room for the possibility of 128-bit floats being added to wasm some day, and on x86-64, aarch64, and powerpc which all have 128-bit long double on Linux, the alignment is 16 bytes.
