From 2074615a13a4f250e0a4e3f6ec8e3733b950a783 Mon Sep 17 00:00:00 2001 From: David Mosberger-Tang Date: Fri, 18 Feb 2005 19:09:00 -0700 Subject: [IA64] use fc.i for fluch_icache_range() This is a small patch to switch fluch_icache_range() to use fc.i instead of fc. This would save time on processors which can establish i-cache coherency without flushing the cache-line out to memory (not that any current processors do). On existing processors, fc.i behaves like fc. The only caveat is that very old assemblers may not know about fc.i yet.
