** DEVELOPMENT BUILD
To help development we assume ./configure sets these variables for make
- CC -- gcc
- CC32 -- i686-unknown-linux-gnu-gcc (or on x86, also gcc)
- CC64 -- gcc for use with Mes C Library: -nostdinc, -nostdlib
+ CC -- gcc (or i686-unknown-linux-gnu-gcc sans libc)
GUILE -- guile
HEX2 -- hex2
MES -- unset
prefix -- ""
Mes is supposed to serve as a full equivalent for Guile, however Mes
-~30 times slower than Guile. That's why we usually don't use Mes
-during development.
+is still about 2 to 10 times slower than Guile. That's why we usually
+don't use Mes during development.
Gcc is used to verify the sanity of our C sources.
i686-unknown-linux-gnu-gcc is used to compare hex/assembly, to test
the gcc variant of Mes C Libirary.
-Target prefix: mes-gcc.
+Target prefix: x86-mes-gcc.
-gcc (CC64) -nostdinc,-nostdlib is used to compare hex/assembly, to test
-the 64bit variant of Mes C Library.
-Target prefix: x86_64-mes-gcc.
+gcc -nostdinc,-nostdlib is used to compare hex/assembly, to test the
+64bit variant of Mes C Library. Target prefix: x86_64-mes-gcc.
Guile is used to develop MesCC, the C compiler in Scheme that during
bootstrapping will be executed by Mes.
-mes is built from src/*.c and some out/src/*.h files that are snarfed from
-src/*.c by build-aux/mes-snarf.scm.
-
-Running ./make.scm produces a `script' file.

** BOOTSTRAP BUILD
+ ./configure.sh [--prefix=PREFIX]
./build.sh
+ ./install.sh
-In bootstrap mode, we don't have gcc (CC), we don't have a 32 bit gcc
-(CC32), we have no guile (GUILE)...but we should have hex2, M1, and
-mes.M1. That's a bootstrap problem which is currently ignored by
-using the mes-seed package. mes.M1 will be produced by M2-Planet from
-mes.c.

* ROADMAP
** TODO
*** release 0.x, unsorted
- - replace bootstrap utils with Gash: bash, coreutils, grep, gzip,
+ - mes: prepare src/mes.c for M2-Planet transpiler,
+ Jeremiah branched-out from mes; see https://github.com/oriansj/mes-m2.
+ - mes/mescc: proper docstrings, api reference documentation.
+ - replace bootstrap-binaries with Gash: bash, coreutils, grep, gzip,
sed, tar.
+ - mes: real module support, Guile compatible (define-module,
+ define-public, export).
+ - mescc: ARMv7/AArch64 support.
+*** after release 1.0
+ - replace initial gcc-2.95.3 with gcc-3.x or 4.x
+ - use 3rd party libc (ucLibc, dietlibc, ...) after Mes and reduce
+ need for bootstrappably-rich Mes C Library?
+ - mes/mescc: bootstrap a `bootstrap-Guile' before bootstrapping tcc?
- tcc: remove or upstream patches from tcc-boot.
- tcc: build 0.9.27 directly instead of via 0.9.26, see tinycc
wip-bootstrappable@0.9.27 branch
- - mes: performance!
- - mes: prepare src/mes.c for M2-Planet transpiler,
- Jeremiah branched-out from mes; see https://github.com/oriansj/mes-m2.
- - mes: real module support, bonus for supporting Guile's define-module/define-public syntax.
- mes/mescc: bootstrap a minimal-Guile?
- + libguile/{eval,init,list,strings,values,..}.c
+ + libguile/{eval,init,list,strings,values,..}.
+ ice-9/eval.scm
- mescc: have mes-tcc pass all scaffold/tests, scaffold/tinycc tests.
- - mescc: support long long?
- - mescc: full support for floats?
- - mescc: some success with 8cc,pcc,guile/libguile/eval.c?
- - build: guile/guix/make.scm: add file-types, intermediate, hash all dependencies
- - get full source syntax-case up (Andre van Tonder?) OR drop it.
- https://srfi.schemers.org/srfi-72/srfi-72.html
- psyntax/syntax-case and rewrite Nyacc without syntax-case+R7RS Ellipsis.
- - mescc: split-off MesCC as as standalone Guile C compiler project.
-*** release 1.0
- - more architectures (does GuixSD require this, i.e. before 1.0?).
+ - syntax-case bootstrap problem
+ + resolve portable syntax-case bootstrap, or
+ + get full source syntax-case up (Andre van Tonder?)
+ https://srfi.schemers.org/srfi-72/srfi-72.html, or
+ + ... drop it?
+ - mescc: the Hurd support.
** DONE
+*** 0.19 GNU mes now compiles TinyCC in ~8min and supports building Bash and GNU Tar.
*** 0.18 GNU mes now supports GuixSD bootstrap (x86,x86_64) and has native x86_64 support.
*** 0.17.1 GNU Mes now allows removing glibc, binutils and gcc from the GuixSD bootstrap.
*** 0.17 GNU Mes is now an official GNU project and bootstraps gcc-4.7.4.
* Bugs
+** mes: performance, Mes is now 2-10x slower than Guile.
+** mes/mescc lack support for the Hurd.
+** mes: gcc-x86_64 compiled mes segfaults with small arena, or gc_up_arena.
** mes: gcc-x86 compiled, tests/srfi-13.test number->string INT-MIN fails:
test: number->string INT-MIN: fail
expected: -2147483648
** mes+mescc: parse tcc.c->tcc.E works, compile tcc.E -> tcc.M1 segfaults.
