I wish we had the resources to have an "experimental" jobset always running that we could throw stuff like this on

Randy Eckenrode in #staging:nixos.org (https://matrix.to/#/!UNVBThoJtlIiVwiDjU:nixos.org/$GOAB-0pj06IwTEidSgN3biXYZn_r9yZTViHoL6Y2Yns?via=nixos.org&via=matrix.org&via=tchncs.de)

You can’t compile the stage 1 LLVM with GCC then rebuild it again in a later stage with the stage 1 LLVM? (Are there complications with switching C++ ABIs?)

This is where my idea of splitting out the bootstrap tarballs would be useful. We could compile stage 1 LLVM from GCC but I feel like it may be a better solution to use LLVM prebuilt to build LLVM. Plus it'll likely be better on the eval since we wouldn't likely be needing odd exceptions or overrides.
