[Tack-devel] CVS update

[David G. <dg...@co...>]

Well, the mailing list seems to have come to life again --- not sure what=

happened; I think SF's servers went mad. I suspect that the current discu=
ssion
will continue to dribble in a fairly disjointed manner for some hours yet=
=2E

I'd just like to say that, enthusiasm renewed, I've managed to get the ne=
w
build system up and running in head of CVS. (I did actually post a few da=
ys
ago with an earlier update, but it seems to have gotten lost.) What you g=
et is:

* The ANSI & K&R C compilers
* The Pascal compiler
* Backends for most platforms (except Sparc related)
* All the optimisers (global, peephole, target)
* A reasonable collection of utilities, including the linker and libraria=
n

What you *don't* get are any run-time libraries, so you can't actually us=
e it
for generated real code yet, but it's perfectly suitable for experimentin=
g
with the code generators. I'll reemphasise that this is not a release; it=
's
just a point where head of CVS happens to build.

Plus, I got it all building on NetBSD as well as Linux (although I'm havi=
ng to
do 'ulimit -n 256' on SF's build farm to make it build).

If you want to use this, then:

* You will need to install LLgen 1.0.2 off the website (this is now built=

separately).
* Check out head of CVS via anonymous CVS.
* Do: ./pm configure
* Do: ./pm
* Wait.

pm is Prime Mover, which has its own project on pm.sf.net (currently just=
 an
SVN repository). It still has bugs and it's undocumented, but it's workin=
g
rather well, if I say so myself, and is *far* more straightforward to use=
 than
the ACK's old build system. Its steering files are called 'pmfile'.

It's currently set up to build everything into /tmp/ack-temp/staging.
Eventually, this will get copied out to a destination install directory, =
but
for now the ACK is configured to run from there. So, you can compile a C
program with:

cat > test.c <<EOF
extern int printf(const char* format, ...);
int main(int argc, char* argv[])
{
	printf("Hello, world!\n");
	return 0;
}
EOF
/tmp/ack-temp/staging/bin/ack -v -O6 -ansi test.c -mi386 -c.s

=2E..and a Pascal program with:

cat > test.p <<EOF
program test(output);
begin
writeln('Hello, world!')
end.
EOF
/tmp/ack-temp/staging/bin/ack -v -O6 test.p -mi386 -c.s

(If you get errors when trying different architectures, such as ARM, it's=

probably because noone's gotten round to writing a global optimiser
description file yet (see util/ego/descr). Try -O1.)

Maybe I should try Occam next...
