@janneke @aziz @fsf @fsfe @reproducible_builds @ekaitz_zarraga Indeed! Right now we can bootstrap all the way from #hex0 to #Mes, then use #MesCC to build very first build of #tinycc (we can call it mes-tcc). mes-tcc can then build the next build of tinycc (boot0-tcc). Unfortunately, at the moment boot0-tcc segfaults. Today, I fixed one crash which was due to Global Offset Table being all zeros but it turns out we are now hitting another segfault, so more work is needed.
Spent part of my #RechageDay at #AMD looking at bootstrapping #TinyCC 0.9.26 from #GNUMes on #x86_64 architecture. And thanks to #Mes mantainer @janneke for his help with debugging various issues. We can now build initial #tcc binary and it can even run some simple commands such as --help or -vv.
Unfortunately, we still hit some critical bugs when trying to use this tcc binary to rebuild itself but hopefully we are not far now.
GNU Mes (maxwell equations of software) provides a minimal #scheme interpreter and C #compiler with tooling to build #tinycc that can be used with the Mes C library to compile glibc-2.2.5, binutils-2.20.1, gcc-2.95.3 with which you can build the whole #GNU system.
