From 74a0ba61b1ca96d6bb98889a7d95cd057165da49 Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Mon, 9 Jul 2007 23:49:09 -0500 Subject: [POWERPC] Move inline asm eieio to using eieio inline function Use the eieio function so we can redefine what eieio does rather than direct inline asm. This is part code clean up and partially because not all PPCs have eieio (book-e has mbar that maps to eieio).
