| Look for files named *386* or *FreeBSD* and you'll see what |
| you need to implement for your architecture of choice. |
| The hardest thing is probably the assembly routines: |
| src/lib9/tas-$SYSTYPE.s and src/libthread/asm-$SYSTYPE-$OBJTYPE.s. |
| The former is a test and set used to implement shared-memory |
| spin locks. The latter is a stripped down setjmp and longjmp |
| used to implement stack switching in the thread library. |
| Also, src/libthread/$OBJTYPE.c needs to know how to set up a stack |
| frame for the given object type. |
| If you're only interested in mk and sam, you don't need to |
| write any assembly to do a port. Samterm requires everything |
| though, since it uses libthread. |
