Last year (2022) the big milestone for OpenRISC was getting the glibc port upstream . Though there is libc support for OpenRISC already with musl and ucLibc the glibc port provides a extensive testsuite which has proved useful in shaking out toolchain and OS bugs.
The upstreamed OpenRISC glibc support is missing support for leveraging the OpenRISC floating-point unit (FPU) . Adding OpenRISC glibc FPU support requires a cross cutting effort across the architecture’s fullstack from:
