| 3 | Look for files named *386* or *FreeBSD* and you'll see what |
| 4 | you need to implement for your architecture of choice. |

| 6 | The hardest thing is probably the assembly routines: |
| 7 | src/lib9/tas-$SYSTYPE.s and src/libthread/asm-$SYSTYPE-$OBJTYPE.s. |
| 8 | The former is a test and set used to implement shared-memory |
| 9 | spin locks. The latter is a stripped down setjmp and longjmp |
| 10 | used to implement stack switching in the thread library. |
| 11 | Also, src/libthread/$OBJTYPE.c needs to know how to set up a stack |
| 12 | frame for the given object type. |
| 13 | |
| 14 | If you're only interested in mk and sam, you don't need to |
| 15 | write any assembly to do a port. Samterm requires everything |
| 16 | though, since it uses libthread. |
