wasi calls from wasm start function
Opened this issue · 5 comments
is it allowed to call wasi functions from wasm start function?
- wasip1, if it matters.
- i mean this https://www.w3.org/TR/wasm-core-2/#syntax-start start function, not "_start".
i suppose the answer is no because, with some embedder apis, it's tricky or impossible to get a reference to the exported memory before the start function is called.
anyway, is it specified anywhere in the spec?
Yes, this issue has been much discussed.
See WebAssembly/design#1160 and
#487
#19
I'm not sure if any of those discussions lets to documentation changes anywhere.
The status quo is that _start
is reserved for use by the linker (at least with llvm/wasm-ld) and cannot run user code.

do you mean wasm start function?
Yes, sorry I meant the wasm start function.
As you can see the terminology is confusing here :)
