Hi! You may heard about some tries from me to bootstrap GCC. This is now working for x86_64¹. There is a possibility that not much work is needed to get this working for more architectures as well.
I’d like to offer a lot of fixes and patches to GNU Mes 0.27², which enable to compile an upstream TCC form 2025-05-28 with minor fixes, mostly because of issues in NYACC when parsing macros. Ekaitz, is there a chance that you could try to build this TCC on RISC-V? Jan, I’d be happy to start a discussion with you on how to contribute these patches to GNU Mes. I also found and fixed three problems with awk from GNU Gash-Utils³ while using it for more packages on the way to GCC. Timothy, maybe you like to take a look? The only binary blob in use is the pre-built Guile. Maybe I’m cheating, but I use (default-guile) at the very beginning to build a Bootar package and to get the pre-built Guile. From there on this pre-built Guile is used to start over and build Bootar again, then Gash and further. I think (default-guile) is in use anyway, so why should we trust even more binary blobs? I’m interested in your opinions on this. Nearly all packages in the chain⁴ are up-to-date, I avoided old versions as much as possible. Whenever troubles with early packages like Gash-Utils got too limiting, I added the original package like GNU sed. It could make sense to move some packages like GNU Tar up the chain to benefit from a speed improvement. To prevent conflicts with existing package names I’m currently using upper-case package names with a bootstrap suffix. Maxim, I’m sorry for this late “reply”. The remaining effort to get it into this state was more than I guessed. Unfortunately I did not look yet into your code. My next step from here should be another GCC 15 making use of the GNU C Library. I’d be happy to get some feedback.
