I was trying to bootstrap Rust beta (1.43.0) for Linux/riscv64 on Ubuntu 20.04 host. I have done that before successfully with 1.42.0 (stable). This time I also added llvm-libuwnind to config.

This failed:

Do we need something like this but also for riscv64?

Any pointer?

The C code has been disabled by this commit: e4f46b9

So it's not the same fix as the MIPs issue. It seems like first we need to add the RISC-V C compiler somewhere so then we can revert e4f46b9

This seems to be the place we need to add RISC-V compiler support to: https://github.com/rust-lang/rust/blob/master/src/ci/docker/host-x86_64/dist-various-1/Dockerfile#L108

ci: docker: dist-various-1: Include RISC-V C compilers
f64f64d 
The compiler-builtins for RISC-V are missing some key functions, such as
__bswapsi2 [1].

We can't just pull in the LLVM compiler-rt builtins as the rust-lang/rust
distribution container doesn't have a C compiler [2].

This patch adds RISC-V C compilers to the CI Dockerfile as the first
step towards enabling LLVM compiler-rt builtins for RISC-V Rust.

Now that rust-lang/rust#117654 has been merged
the rust-lang/rust distribution containers contain RISC-V C compilers.

This means that we can now enable the "c" feature fallback.
