This commit fixes two things:
* It changes the alignment to 16 bytes (from 4), to match max_align_t
in C.
* It manually aligns heapStart on WebAssembly, to work around a bug in
wasm-ld with --stack-first (see https://reviews.llvm.org/D106499).
|
Perhaps this can also add a test from #2010 ? |
|
Hmm, perhaps yes. I'm not sure though as checking for alignment does not guarantee anything: the pointer can also be aligned by chance. |
|
Either way, this looks good to me 👍 |
