30x? Oof

I know that I regressed quickjs recently when I fixed handling of unions. It’s a fixable issue, I just haven’t gone back and fixed it yet.

I definitely don’t see 30x overhead on anything else I run.

But thanks for pointing that out, I should probably actually fix the union handling the right way.

(What’s happening is every time quickjs bit casts doubles to pointers, that’s currently doing a heap allocation. And it’s obviously not needed. The simplest compiler analysis would kill it. I just turned off the previous instance of that analysis because it had a soundness issue)

Thanks for the response, that’s useful to know. It’s honestly amazing (to me) that Fil-C works at all, and I’m sure the performance will continue to improve.
