Re: [9fans] New Language [Myrddin] On Plan 9/amd64
That looks really neat! One question: are runtime bound checks really necessary? I would at least like a seperate release mode that gets rid of them.

Ah, I forgot about that: This is a bug with Ape's printf; It's missing
the %z specifier to print size_ts.
The below patch fixes it, although I seem to remember that 9atom
has a rewritten ape -- I'm not sure if this will apply:

Re: [9fans] New Language [Myrddin] On Plan 9/amd64
I could do it pretty easily, although I'd be curious to see what you think makes it harder to write a kernel with bounds checks. At least for me, I'd rather keep them the same. At least on with Intel's current out of order processors, they are shockingly cheap, and can be made much cheaper with (not-yet-implemented) optimizations like value range propagation. If it actually does make a significant performance difference (benchmarks, please), I'd gladly add in a flag. For doing the benchmarks, just delete line 780 of 6/simp.c On Sun, 04 Jan 2015 09:13:20 -0600 Ryan rym...@gmail.com wrote: That looks really neat!

Not yet. I haven't needed a 9p implementation yet; no file servers have bubbled to the top of my queue of code to write at this point, and I'm wary of writing APIs without at least some user in mind.
