Not unless you get promoted for writing more efficient code.

I filed the bug: https://github.com/llvm/llvm-project/issues/204883

The last time I evaluated doing protein folding it required gigabytes of disk-data to make it happen. If there's a way to do it without needing gigabytes of disk-data, I'm at least interested in hearing it out.

If it's dumb and it works, is it really dumb?

I'm gonna have to file the bug without a minimal reproduction case. The issue seems to be those try_table blocks getting nondeterministically reordered at link time (is it using machine pointers for iteration order?). Sadly I'm observing this with a local checkout of binaryen, so it may take a while for you to find the minimal reproduction case.

I tried doing that at first. I kept running into edge cases that made the whole thing fall to ribbons. I gave up and am just falling back to what I know works: compiling the WASM to JS.

That's great. I love that for you. Please leave me alone.

Surprisingly, cherry-picked examples to prove a point are cherry-picked examples to prove a point.

It's a conscious design choice. Doing that gets you considered a botnet/malware. I don't want Anubis to be considered a botnet/malware.

Nix doesn't help when the issue is a compiler bug, sadly.

Patches welcome. I'd love to do protein folding too.

Sadly my initial test case is binaryen which has 290 compilation units. I will try though.

Thank you, this will be very useful.

This might be the first time in my career I have genuinely found a compiler bug. I've been operating under the axiom of "don't assume it's a compiler bug, assume you're fucking it up somehow". When you get to the point that disabling ASLR makes it consistent intra-host I think I've won the right to at least suspect a compiler bug is at play.

I'll go file it upstream after work today.

iOS Lockdown Mode also implements this configuration.

I'll try and make a minimal reproduction case and file a bug. Do you know if any tooling that can take a binary and fuzz it down to a minimal reproduction set?
