Re: [Caml-list] [ANN] RISC-V backend for the native-code OCaml compiler

[Nicolas Ojeda Bar <n.oje.bar@gmail.com>]

Hi Richard,

- As Gabriel explained the upstream is the branch riscv64-unknown-elf
of the official 4.02 release found at
github.com/nojb/ocaml.  It should be trivial to bring it up to date (I
will do it if there is interest).

- I have been following your efforts on the RISC-V mailing list and I
agree that it would be great to have
OCaml running in Fedora userland on RISC-V.  The native-code backend I
wrote was only tested with the spike simulator
(I don't remember the details now, but I had to build OCaml with
newlib instead of libc for this).

Do get back to me if you detect any issues with the port - I haven't
updated it in quite some time and some adjustments may be
needed.

Are there any step-by-step instructions on how to run Fedora on RISC-V
at this stage ?

Thanks!

Best wishes,
Nicolas
