# Mu provides 3 canonical ways to translate unsafe SubX programs:
|
|
|
|
|
# 0. The C++ translator 'bootstrap translate' can generate traces for
|
|
|
|
|
# debugging on Linux or BSD or Mac, but doesn't support any syntax sugar.
|
|
|
|
|
# 1. The self-hosted translator can be run natively on Linux using
|
|
|
|
|
# 'translate_subx'. It is fast and supports all syntax sugar, but you get no
|
|
|
|
|
# trace for debugging.
|
|
|
|
|
# 2. The self-hosted translator can be run emulated on Linux or BSD or Mac
|
|
|
|
|
# using 'translate_subx_emulated'. It supports all syntax sugar. However, it
|
|
|
|
|
# can be slow if you generate traces.

# This script fills in the gap above by stitching together aspects from
|
|
|
|
|
# multiple approaches. It translates syntax sugar natively, but emulates lower
|
|
|
|
|
# levels using the C++ translator. The result is complete and relatively fast
|
|
|
|
|
# even when generating traces.
|
|
|
|
|
#
|
|
|
|
|
# The cost: it needs Linux. There is no script to generate traces while
|
|
|
|
|
# running emulated on BSD or Mac. That's often impractically slow.

7842 - new directory organization
Baremetal is now the default build target and therefore has its sources
at the top-level. Baremetal programs build using the phase-2 Mu toolchain
that requires a Linux kernel. This phase-2 codebase which used to be at
the top-level is now under the linux/ directory. Finally, the phase-2 toolchain,
while self-hosting, has a way to bootstrap from a C implementation, which
is now stored in linux/bootstrap. The bootstrap C implementation uses some
literate programming tools that are now in linux/bootstrap/tools.
So the whole thing has gotten inverted. Each directory should build one
artifact and include the main sources (along with standard library). Tools
used for building it are relegated to sub-directories, even though those
tools are often useful in their own right, and have had lots of interesting
programs written using them.
A couple of things have gotten dropped in this process:
- I had old ways to run on just a Linux kernel, or with a Soso kernel.
No more.
- I had some old tooling for running a single test at the cursor. I haven't
used that lately. Maybe I'll bring it back one day.
The reorg isn't done yet. Still to do:
- redo documentation everywhere. All the README files, all other markdown,
particularly vocabulary.md.
- clean up how-to-run comments at the start of programs everywhere
- rethink what to do with the html/ directory. Do we even want to keep
supporting it?
In spite of these shortcomings, all the scripts at the top-level, linux/
and linux/bootstrap are working. The names of the scripts also feel reasonable.
This is a good milestone to take stock at.
