A major milestone in bootstrapping

A major milestone in bootstrapping

[Jeremiah]

Today I am proud to announce a combo of releases with major milestones.

First stage0, reached Release version 0.2.0; which includes the following:
A 250byte hex0 bootstrap binary that is self-hosting and builds hex1,
which builds hex2, which bootstraps M0 macro assembly which has been
used to make:

The world's FIRST C compiler written in M0 macro assembly, supporting:
structs
unions
inline assembly
function pointers

http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage2/cc_x86.s

which is capable of compiling reproducibly:

The newly released M2-Planet V1.0
https://github.com/oriansj/M2-Planet

Which is a self-hosting C compiler which is 100% deterministic by design
with support for all the features needed to build the pieces of:

mescc-tools
https://savannah.nongnu.org/projects/mescc-tools

which is capable of building M2-Planet from it's M1 macro seed.

Soon we hope to finish the MesCC bootstrap from M2-Planet and then we
will have a complete bootstrap path from 250byte hex0 all the way up to
gcc ^_^

Interesting... I'm looking at

  https://github.com/oriansj/M2-Planet/blob/master/seed.M1

How was it written?  It seems like a monumental task to write all that
and keep enough context in one's head!  Then again, I have never written
assembly before...

If you'll notice https://github.com/oriansj/M2-Planet/blob/master/seed.M1#L2

It explicitly says it was generated from stage0 https://savannah.nongnu.org/projects/stage0/
Specifically cc_x86 http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage2/cc_x86.s
Which was built by M0: http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage1/M0-macro.hex2
Which was built by hex2: http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage1/stage1_assembler-2.hex1
Which was built by hex1: http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage1/stage1_assembler-1.hex0
Which was built by hex0: http://git.savannah.nongnu.org/cgit/stage0.git/tree/stage1/stage1_assembler-0.hex0
Which was the 250byte seed used

Well the work started back in 2016 with http://git.savannah.nongnu.org/cgit/stage0.git/tree/Linux%20Bootstrap/hex0.s 
and http://git.savannah.nongnu.org/cgit/stage0.git/tree/Linux%20Bootstrap/hex0.hex 

It was written one function at a time, with the arguments passed in registers and careful preservation of everything passed.

Ah very interesting!  Thanks for the history :)

Wow!  Just Wow!

I have a question though.  It sounds like a bunch of
this is assembly...Is assembly portable?  AKA does/will this
bootstrapped C only be able to run on Intel chips?

I suppose that even if it did, you could cross compile it to other
architectures...
