miniparrot, a first attempt.
Josh Wilmes
I've banged together a first attempt at a miniparrot- that is, something
that can be built on any ANSI C system without anything other than a
compiler.
Right now, as a proof of concept, it's building a source tree and a shell
script which would build miniparrot under gcc. A real version would
include platform-specific build scripts which are a tad smarter- but since
all they have to do now is run a sequence of compile steps, they don't
need to do much other than figure out what compiler to use and how to call
it.
Here's a log of how to use it. The way I would envision this working is
that we would periodically run this and check the results into CVS, so
that there was a miniparrot tree available alongside the real one. We
could tinderbox it as well.
Note: Until the stack direction issue is sorted out, this isn't really
going to work across platforms.

Hello, I'm Configure. My job is to poke and prod your system to figure out
how to build Parrot. The process is completely automated, unless you passed in
the `--ask' flag on the command line, in which case it'll prompt you for a few
pieces of info.
Since you're running this script, you obviously have Perl 5--I'll be pulling
some defaults from its configuration.
Checking MANIFEST...done.
Setting up Configure's data structures...done.
Checking for --miniparrot...Yes..done.
Loading platform hints file...(no hints) done.
Enabling debugging...(none requested) done.
Determining what C compiler and linker to use...done.
Determining what types Parrot should use...done.
Determining what opcode files should be compiled in...done.
Setting up experimental systems...done.
Determining what pmc files should be compiled in...done.
Tweaking ccflags...done.
Determining your minimum pointer alignment...done.
Probing for C headers...done.
Determining some sizes...done.
Determining stack growth direction...done.
Computing native byteorder for Parrot's wordsize...done.
Figuring out how to pack() Parrot's types...done.
Figuring out what formats should be used for sprintf...done.
Determining if your C compiler is actually gcc...done.
Determining architecture, OS and JIT capability...done.
Verifying that the compiler supports function pointer casts...done.
Determining if your compiler supports computed goto...done.
Determining what allocator to use ... (gc) done.

Writing Parrot::Config module...done.
Generating Makefiles...done.
Recording this configuration in myconfig...done.
Moving platform files into place...done.
Generating libparrot.def...done.
Generating core pmc list...done.
Okay, we're done!
You can now use `make' (or your platform's equivalent to `make') to build your
Parrot. After that, you can use `make test' to run the test suite.
Happy Hacking,
The Parrot Team

Great!
I haven't looked deeply, but there is one little quibble I found so far:
In config/auto/alignptrs.pl, there is
if ($miniparrot) {
# we can't guarantee anything about pointer alignment under ANSI C89.
# so we will have to check every byte.
Configure::Data->set(ptr_alignment => 1);
Alas, you can't check every byte. It is true that you can't portably
guarantee anything about pointer alignment. Thus, for example, it's not
guaranteed that you can access things at arbitrary alignment.
In particular, with ptr_alignment = 1 on a SPARC, I get
signal BUS (invalid address alignment) in trace_system_stack at line
491 in file "dod.c"
491 size_t ptr = *(size_t *)cur_var_ptr;

Is there a way to avoid stack walking at all in miniparrot?
What do we do instead? (Nothing?)
Miniparrot's main purpose is to be able to bootstrap parrot by running its
build scripts. Leaking a little memory may be acceptable.

Well, since I currently force all the other *ALIGNMENT #defines to be '16'
in <parrot/headers.h> (See comment on "Alignment problems" in
resources.c), setting ptr_alignment = 16 is probably sufficient and safe
for now. Sorry for not suggesting that explicitly before.
