how do you even write an os with rust?
does it compile to machine code w/o anything else linked to?
Easton Brooks
In order to compile an OS written in Rust, you have to add "freestanding" compilation/linking option to not allow it to get linked with system's libraries. Also, in many cases you have to disable language's security measures, degrading it to security level of C. So, in the end, it doesn't matter.

but how do they do multithread w/o system libraries?
Christopher Parker
They can't use multithreading until they write their own implementation - as simple as that. They have to disable most Rust features, making it work like C with Rust syntax.
Nicholas Allen
> like C with Rust syntax.
So already an improvement.
Luke Rogers
What's in your opinion the most important advantage of Rust syntax over C/C++ syntax?
Angel Anderson
things that are awful in C:
>integer promotion rules
>errno
>globally namespaced and weakly types enums
>bitflags
>arrays vs pointers
>includes as a compilation unit dependency primitive
>type and declaration syntax
so nothing really critical

How does it feel to know that this is 200% UB and the compiler will never warn you about this?

You're retarded. Ripgrep isn't "grep", it's its own implementation which is incompatible with POSIX.

Is &x really undefined? Seems like it would have a defined adress.
Aaron Richardson
Now make the array contents not known at compile time. Not trying to be clever with the loop might also help the compiler optimize it better.

int f(int *const x)

That's not UB either... You are just incrementing the value pointed to by x, which is a constant pointer to int.

You're acting retarded on purpose, huh?

Neither put any warning. And the function isn't even hidden in another translation unit.
Asher Wilson
The order of evaluation of function parameters isn't defined. As you see one compiler chooses to do it let to right, another right to left. Don't blame the language for your inability to read
Asher Martinez

You're acting retarded on purpose, huh?
David Peterson
You're a special kind of a retard. The language clearly defines the evaluation of function arguments to be implementation defined. It is NOT undefined behaviour.
Sebastian Mitchell
It is unethical to continue writing code in non-memory-safe C or C-based languages, for any purpose. Period.
Asher Collins
>the language explicitely doesn't define the behaviour, therefore it's not undefined behaviour

C is security vulnerabilities as a language.
Evan Turner
The difference between undefined and implementation defined isn't worth much. No one should be relying on either.
They are technically different. The value of 'sizeof(int)' is an example of implementation defined behavior.

Which means a lot of code that depends on it is UB hence why Rust is right to provide only fixed-size integer types.
Chase Myers
I have some rust code that runs entirely on microcontroller. Also there's a UEFI target so you can build a bootable OS for x86_64. Basically, it works the same as C on bare metal - you statically link a special executable, possibly with a custom linker script. You only get libcore and not libstd, but that's about the same as C. The UEFI target sets up the linker script for you, but you can also do it yourself.
