如何在 rustc 中使用 gcc 标志

Question

I am trying to run a Rust program on a powerpc arch.

When I build my code in C I use the flag -mlongcall.

I am trying to understand how can I use the "-mlongcall" flag in my rust build. In general, it would be nice to know if I can use flags that I know from gcc in my Rust build.

Answer 1

The solution for the -mlongcall flag is to use the flag: -Ctarget-features=+longcall as suggested in this issue: add mlongcall flag to rustc
