Syn68k has not been actively worked on since about 1995. A few mods
|
2009-06-03 11:02:50 +00:00
|
|
|
have been made here and there to keep up with changes in gcc. Those
|
|
|
|
|
mods may actually interfere with compiling on older versions of gcc.
|
|
|
|
|
Oh well.

For a few years I've been meaning to verify that the code builds,
|
2009-06-02 14:25:10 +00:00
|
|
|
write a little documentation, explain a little history, maybe even set
|
2009-06-03 11:02:50 +00:00
|
|
|
up a mailing list for people, etc... but other things continue to take
|
|
|
|
|
precedence.

On an i386 Fedora 9, this version of Syn68k compiles and produces a
|
|
|
|
|
libsyn68k.a that works with Executor. In a few days Fedora 11 will be
|
|
|
|
|
out, using gcc 4.4. I'll try to make it so that Syn68k works on it as
|
|
|
|
|
well as older Fedora systems too. I'll try to get it so the i386
|
|
|
|
|
version of Syn68k works on gcc 4.1, 4.2, 4.3 and 4.4.

Back in the day, Syn68k was very portable and could be run on non-x86
|
|
|
|
|
boxes. I wouldn't be surprised to find that the non-x86 versions fail
|
|
|
|
|
to work now. However, once the i386 version runs nicely on a variety
|
|
|
|
|
of gccs it may be fun for someone to make the non i386 versions run
|
|
|
|
|
again.

To compile syn68k on a 32-bit i386 system, try
|
2009-06-01 21:45:49 +00:00
|
|
|
|
|
|
|
|
./autogen.sh
|
|
|
|
|
./configure
|
|
|
|
|
make
|
2009-06-02 14:25:10 +00:00
|
|
|
make install
|
|
|
|
|
|
2009-06-04 00:27:34 +00:00
|
|
|
To compile syn68k on a 64-bit x86_64 system, make sure you have all
|
|
|
|
|
the 32-bit libraries you need (on Fedora 10 I needed to install
|
|
|
|
|
glibc-devel.i386 and libgcc.i386) then try this hack
|
|
|
|
|
|
|
|
|
|
./autogen.sh
|
|
|
|
|
CC='gcc -m32' ./configure --build=i686-pc-linux-gnu --host=i686-pc-linux-gnu
|
|
|
|
|
make
|
|
|
|
|
make install
|
|
|
|
|
|

|
|
|
To test syn68k, run test/syngentest and compare the output to
|
2009-06-05 07:21:40 +00:00
|
|
|
test/output/10000. It should be the same. If you want to be
|
2009-06-05 06:56:39 +00:00
|
|
|
more thorough, you can use other command line options and compare the
|
|
|
|
|
results to other files, as described in test/output/README.

The code in runtime/i486-cleanup.pl no longer gets rid of all the
|
|
|
|
|
cruft in the trailer. It's quite possible that the code in
|
|
|
|
|
runtime/i486-optimize.pl doesn't do the right thing either.

My email address is still <ctm@ardi.com>, although ARDI itself is

|
|
|
|
defunct. I get a ridiculous amount of spam and will quite possibly
|
|
|
|
|
not see email addressed to me.
