I would like to work on this but I'm not familiar with Then I can use How do you get the assembly output ? Also, I don't see any tag/release. Do you expect to have |
I am not familiar with it either, but from what I understand, it is currently a transpiler to C without native codegen. So I would have one entry in CE to show the C output; and perhaps another for that + GCC and/or + Clang.
I think having a build from time to time when a major milestone is reached is enough for the moment (like when a newer Rust compiler version gets bootstrapped) . However, perhaps @thepowersgang would welcome nightlies nevertheless! |
Initially wanted to add existing versions, but small issues would require some workaround to make it work. Instead, use nightly, at least until a new release is published. compiler-explorer/compiler-explorer#2643

I've a setup working locally. I think it's easier to focus on upcoming releases and ignore anything earlier because that would need some workarounds (not hard, but not sure this is worth it). When a simple fix is merged, I'll start pushing PR here to add the compiler. As a first goal, I'll treat the C as the final product (I still need to see how to display this correctly). Maybe there will be something to chain this C into another compiler, but that's a different topic. |
Add the needed base for new mrustc compiler. https://github.com/thepowersgang/mrustc mrustc is transpiling Rust to C and is mainly used for bootstraping rustc. This change treats the C output as the final product (as is assembly for GCC/clang). It is not easily possible to automatically plug this C to other C compilers to get assembly or executable. fixes compiler-explorer#2643
Add builder for mrustc. This is currently needed because mrustc does not provide binary snapshot for its releases (and also because mrustc until recently would always invoke the local C compiler as its last step, which is not wanted). refs compiler-explorer/compiler-explorer#2643

Hope to have everything correct here.

mrustcis a Rust compiler written in C++.While it is mainly intended as a way to reduce the long bootstrap chain of
rustc, it can compile some non-rustccode too.The text was updated successfully, but these errors were encountered:
