Hi All,
With this patch squeak-vm builds and runs on my macppc machine. I've
had to make 3 changes. I've removed the -mno-fused-madd which doesn't
seem to exist on clang. I've changed f0 to just 0 in the powerpc
specific inline asm, not sure about this, but I thought the type of
register was implicit anyway. Finally, and this change affects all
platforms, I had to change the order of linker arguments; without this
I got a bunch of linker errors relating to the plugins. If there's
anything else I need to do, let me know.
I've only really tested it by clicking around in the default image,
which seems to function well, though I plan on having a play with
Squeak some more later.
