[M3devel] help booting I386_DARWIN?

[Jay]

Right. Look at I386_DARWIN.
It probes for this.
You have two choices.
 - difficult -- put a newline after each lock
  Their assembler does understand that I recall.
 
 
 - get a newer assembler; that's what I did
  I386_DARWIN will tell you what version I used, I don't know if older works.
 
 
or maybe we could/should change cm3cg here.
Heck, maybe there's a change in Apple's gcc to merge in.
 
 
Or maybe, heck, just remove all occurences of lock.
You only have one processor, right?
