alt Hacker NewsI'd guess that the issue is running the `%install` and `%check` stages of the .spec file. The Python library rpy (to pull a random example from Marcin's PRs) runs rpy's pytest test suite and had to be modified to avoid running vector tests on RISC-V.
Obviously a solvable problem to split build and test but perhaps the time savings aren't worth the complexity.

Maybe the tests could be run with user-mode qemu instead of the whole thing running under qemu or on RISC-V hardware. Could possibly be more or less seamless with binfmt_misc being set up in the builders.
