Google “Nebulet” and beware a kernel that runs all of user space in ring 0 by using web assembly. The next logical step would be whether the kernel itself can be written in web assembly.

The people working on GCC are also mostly paid by companies, e.g., like Red Hat. The moment these companies back out, the same thing will happen to GCC. The root of the problem is that very few people find it "FUN" to implement C+

So what did you learn out of this, and what would you do differently? What do you think people should do differently when reporting these issues?

And to give some examples, while you could maybe ignore ionization for the aerodynamics of an F22 travelling at Mach 3, you probably could not ignore them for a school bus travelling at Mach 3.

Can't answer that question, but suppose you break it free, then what ? It would be like maintaining a separate appstore for iPhones.

Is Rust `str` builtin? I thought it was just a `struct str([u8]);` (a dynamically-sized type).

That's rarely the case. Leadership is usually representative of merit, and merit comes from putting in the work.

FWIW these are not "Amazon employees that infiltrated the Rust ranks to take over". Mozilla fired everybody, and companies heavily invested in Rust like Amazon, Facebook, etc. hired them. So over night some people have labeled the

Modules is arguably another failure. The main goal of modules is to improve compilation times, but if you already have a modularized code base, and are using PCH, then modules don't improve compile-time, at all. Migrating from PCH to m

We had quite a bit of existing FP hardware before the IEEE spec. Code using that hardware was not portable, because each FP unit did things subtly (and sometimes not that subtly) different. All those already existing hardware units were alr

Can you summarize your claim ? AFAICT, you are trying to say that current standardized certification processes aren't rigorous enough, and that you should be doing more. I agree 100%, this is why we are using Rust, seL4, etc. No one re

I thought that mrustc was a different more portable way of solving the bootstrapping problem, since it compiles Rust to C.

Plus I see the main value of GCC Rust in helping improve the Rust spec, so all bugs uncovered are definitely worth fixing.
