Irreducible control flow in Wasm

This is a summary of current discussions, and a follow-up to our recent meetings, prompted by the issue here. Anyone who's been following along with the last few weeks of discussions and presentations might wish to skip directly to the follow-up part.

What is irreducible control flow?

Reducible control flow is the control flow directly representable through semi-structured control flow constructs (loops, conditionals, and break/continue). It can be characterised in terms of a property of the control flow graph that all loops are single-entry. For more details, see the diagram and "Reducibility" subsection here.

Irreducible control flow is roughly "everything else". For example, goto into the middle of a loop would result in irreducible

So there were a few threads going around recently about a challenge to write the longest sequence of keywords in Javascript:

• https://twitter.com/bterlson/status/1093624668903268352
• https://news.ycombinator.com/item?id=19102367

There are, however, a few problems:

• These solutions use non-keyword tokens (null, true, false are actually Literals, not Keywords)
• One of the solutions isn't quite valid (new super)

Custom sections in the text format

This page describes a proposal for representing custom sections in the text format.

Rationale

Currently it is impossible to round-trip a WebAssembly module between the binary and text formats without loss of information because there is no way to

Testing the matrix.org client-server API

Matrix is:

an open standard for decentralised communication, providing simple HTTP APIs and open source reference implementations for securely distributing and persisting JSON over an open federation of servers.

It's pretty fantastic, if you think on the massive problem of fragmentation all across the web. They've created an easy to use API, and you can do a kludgy test using curl from the terminal (*nix, mac, win). See: http://matrix.org/docs/howtos/client-server.html

It's pretty straightforward to do a quick test. I have an account at https://matrix.org / https://vector.im, so I used that to get a token.
