From the Linux/PowerPC FAQ: ======================================================================== ============= Is Linux/PowerPC little or big endian ? Big. PowerPCs take their instructions big end first, but can be set to take their data either way. Set for little-endian data, a PowerPC slows down about 3% (this number is unconfirmed). Linux/PowerPC is big-endian for the following reasons: 1) The PowerMac operating system is big-endian; 2) AIX, the IBM POWER/PowerPC operating system, is big-endian; 3) Net-order is big-endian; 4) It is a physical fact, like gravity, that big-endian is The Right Way. ======================================================================== ============= Does this make Linux/PPC and AIX "wrong?" :) Anybody know of the 68030 Mac port of BSD is also big-endian? -Eric Bennett (ericb@psu.edu) Drawing on my fine command of the language, I said nothing. -Robert Benchley
