@ekaitz_zarraga and I have finally bootstrapped #TinyCC on #RISCV starting from GNU #Mes and #MesCC (and eventually tiny #hex0 binary if you go further back).

The binary that we have built is self-hosting and can build itself, though perhaps a few more bugfixes will be needed to reach the newest version of tcc.

#RISCV Adventures II: #Hex0

@janneke and I were trying to fix 64-bit (#amd64 for now) #GnuMes bootstrap. After applying some fixes to M2-Planet and #mes we were able to bootstrap mes-m2 binary from #hex0. And it's working well enough to rebuild itself with #mescc.

This is expected to be in the next releases of mes 0.25 and M2-Planet 0.11.

#BootstrappableBuilds #stage0

#Stage0 of the #guix full source bootstrap is commented well enough that you can get a sense of what's going on fwiw
