Reverts WebAssembly/binaryen#4889 The spec is unclear on this, and that PR moved us to do what V8 does. But it sounds like we should clarify the spec to do things...

Extra pass for v128 operands in exported functions and globals?

2

At current moment, we can produce such code: ```wat (func (export "a") $a (param $0 v128) (result v128) ;; [v128] -> [v128] local.get $0 local.get $0 i32x4.mul ) ``` But...

Creating relocatable binaries via AST

17

It doesn't appear that binaryen's AST has a way to include [reloc sections](https://github.com/WebAssembly/tool-conventions/blob/master/Linking.md#relocation-sections). What's everyone doing today with binaryen? (not using LLVM) Didn't see any discussions around a desire to...

Simplify mutable globals with single write in "start"

1

It looks like simplify global pass doesn't take into account v128 types. For example: ```wat (module (global $g (mut v128) (v128.const i32x4 0x00000000 0x00000000 0x00000000 0x00000000)) (start $~start) (func (export...
