From 12822bc272e857544476cef9175462711899008b Mon Sep 17 00:00:00 2001 From: GOTO Masanori Date: Tue, 28 Jun 2005 20:45:03 -0700 Subject: [PATCH] headers: enable ppc64 ___arch__swab16 and ___arch__swab32 This patch cleans up asm-ppc64/byteorder.h to enable ___arch__swab16 and ___arch__swab32 which are marked TODO currently. It removes ___arch__swab64 because ppc64 does not have short instruction combinations for swab64, the recent gcc generates enough smart code that is equivalent to hand assembled code under my tests.
