(wasm-ld) Any fundamental problems with linking a shared wasm library statically?
...hink relocation functions are basically just a list of statements
(in a C-like language) `memory_base + <offset> = <address of symbol> +
<constant>`. The RHS can also be `<table base> + constant`. So I think it could
be run at link time.
Alternatively, I think we could run $__wasm_call_ctors as first thing in a
linker-generated main function after updating memory_base and table_base of the
imported module and it'd apply the relocations.
Would this make sense? I'm new at wasm and not too experienced in linking (just
a happy user of ld.lld and gold) so it's possible that I...

Wasm, start function, and default globals
Apologies if there is a better forum for these questions. Please redirect me if so.
I’ve been using the clang/wasm-ld tools to experiment with some basic examples, and there’s a couple things I’m wrestling with.
1) How to denote a function as the “start” function (https://webassembly.github.io/spec/core/binary/modules.html#start-section)
2) How to avoid the defaulted __heap_base global.
I’ve
