From c5ec1983e45d25446a023e98207e30ab1bf2311a Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 29 Jan 2008 10:14:59 +0000 Subject: [MIPS] Eleminate local symbols from the symbol table. These symbols appear in oprofile output, stacktraces and similar but only make the output harder to read. Many identical symbol names such as "both_aligned" were also being used in multiple source files making it impossible to see which file actually was meant. So let's get rid of them.
