Subject: wip-bootstrap updated
I've updated the wip-bootstrap branch[0] for Mes[1] 0.13. It has new
mes-boot and tcc-boot packages. mes-boot is a bootstrap version of
Mes; it only depends on mescc-tools and a previously compiled mes.M1
seed. Likewise, tcc-boot depends on a precompiled tcc-seed. Also,
tcc-boot uses a heavily patched version of the tcc sources.
Mes 0.13 is the first release that can bootstrap a fairly functional
tcc-boot. This bootstrapped tcc passes 67/68 C tests that were created
for MesCC. It can compile a version if itself where float, long long
and bitfield are patched out...but linking fails. This amazing
compiler can now be played with by doing something like
--8<---------------cut here---------------start------------->8---
git checkout wip-bootstrap
make
./pre-inst-env guix build tcc-boot # may take ~2h
./pre-inst-env guix environment --ad-hoc tcc-boot
mes-tcc --help #duck and run
--8<---------------cut here---------------end--------------->8---
The next big effort will be to make this mes-tcc fully functional and
integrate this with GuixSD. To give you a taste of that,
here's latest bug I'm currently looking at (pretty printed comments
are only added when Guile runs MesCC, the problem is in LEA)

We also need to remove some shortcuts that we took, most notably:
mes-seed[3]. This seed consists of 1MB of M1 code. mes.M1 is
produced by compiling mes.c using MesCC, the C compiler written in
(Guile) Scheme that comes with Mes. Although that's really terrible,
it's probably a big step forward: currently GuixSD uses ~250MB of
binary seed: the bootstrap binaries.
The plan is to replace the mes.M1 seed with mes.M2 and compile this
new mes.M2 seed using the brand new M2-Planet[2]. M2 is basically
simple C with structs, without preprocessor. This will reduce the
seed size by a factor of 10 while making it much more readable.
An excerpt of the TODO I keep in Mes' BOOTSTRAP document
--8<---------------cut here---------------start------------->8---
* TODO
** have tcc-boot's mes-tcc compile a fully functional tcc
*** mescc: fix unknown bug.
*** mescc: support function-static.
*** mescc: support/grok global static.
*** mescc: support unsigned comparison, arithmetic.
*** mescc: support long long (do we need long long to get long long in tcc)?
*** mescc: support bitfield (do we need bitfield to get bitfield in tcc)?
*** mescc: support float (do we need float to get float in tcc)?
** have bootstrapped tcc compile gcc-4.7
** remove or upstream patches from tcc-boot
** prepare src/mes.c for M2-Planet[2] transpiler
** integrate with GuixSD
** x86_64, arm, the Hurd
