<vasi>Googulator: Finally got the Azure Linux bootstrap working!!

<vasi>Added it to my repo

<ekaitz>people at nlnet just sent me this: https://pnut.sh/

<ekaitz>what are your feelings about it?

<ekaitz>i'm not sure if that's useful in our current bootstrapping chain like the one in live-bootstrap

<nimaje>where would you have a posix shell, but not a C compiler, so that you could use that to use as replacement of a C compiler? and it is written in C too, so while it seems like a cool project I don't see a use

<ekaitz>nimaje: that's a good point. In guix we have gash, which could do some of this work

<matrix_bridge><cosinusoidally> See https://github.com/fosslinux/live-bootstrap/pull/524 for some discussion of pnut and live-bootstrap by the main author of pnut. I created a variant of pnut that can be compiled by cc_x86 and (hackily) integrated that into live bootstrap https://github.com/cosinusoidally/live-bootstrap/pull/6/files

<ekaitz>very interesting

<matrix_bridge><cosinusoidally> The stock version of pnut is probably also very close to being compilable by cc_x86 or M2-Planet

<ekaitz>and Mescc?

<matrix_bridge><cosinusoidally> It skips it.

<matrix_bridge><cosinusoidally> pnut can build the tcc-bootstrappable version from live-bootstrap

<ekaitz>i'm more interested on skipping tcc than mescc heeh

<ekaitz>hopefully we can do both

<matrix_bridge><cosinusoidally> I think both pnut and mescc would struggle to build GCC. pnut can't generate separate object code files so you'd probably need to build GCC in one go. I don't know for sure, but I would assume pnut has complete enough support for C so it theoretically could compile GCC. I assume mescc would take quite a while to compile GCC.

<ekaitz>yeah... I was thinking on skipping both tcc and mescc and go directly from pnut to gcc

<ekaitz>or make mescc faster (i'm working on that) and go directly to GCC

<matrix_bridge><cosinusoidally> nimaje: posix shells are installed by default on every posix system, but C compilers are not.

<matrix_bridge><cosinusoidally> I think his intention is to ship the shell source code artefact and use that to bootstrap on systems without a C compiler.

<matrix_bridge><cosinusoidally> ekaitz: does object code generated by mescc use the same calling convention as GCC? If so it might be possible to replace object code files one by one with ones generated by mescc (though presumably that would also need a conversion pass from the hex2 output from mescc into a form that could be linked)

<ekaitz>I'm not sure about that

<matrix_bridge><Andrius Štikonas> cosinusoidally: no at the moment mescc generates hex2 files

<matrix_bridge><Andrius Štikonas> So not compatible with GAS tools

<matrix_bridge><Andrius Štikonas> Maybe i should say not compatible with binutils

<matrix_bridge><Andrius Štikonas> And calling convention is almost surely different too
