which mentions msync. But gcc doesn't know msync! It even says that msync is a replacement for sync

Is that sync 2, or something else?

Something else. They have msync and mbar.

Those documents describe the "PowerPC Book E" Architecture. The E is for Embedded. There has never been a Mac with a Book E part in it.

The PowerPC G5 is a "PowerPC/AS" Architecture part. <http://www-128.ibm.com/developerworks/linux/library/l-powarch/>.

Parts found in a Mac prior to the G5 are "PowerPC" except the 601, which was both POWER and PowerPC.

Arch Pub2 Appendix A and B have the test and set routines in assembly.
