From 871fbe6a506496c6123d753e54bc91ab3b597daf Mon Sep 17 00:00:00 2001 From: Mark Kettenis Date: Mon, 15 Mar 2004 22:38:21 +0000 Subject: * i386-linux-tdep.c: Update copyright year. (i386_linux_svr4_fetch_link_map_offsets): Remove function. (i386_linux_init_abi): Set solib_svr4_fetch_link_maop_offsets to svr4_ilp32_link_map_offsets instead of i386_linux_svr4_fetch_link_map_offsets. --- gdb/i386-linux-tdep.c | 54 ++++++++------------------------------------------- 1 file changed, 8 insertions(+), 46 deletions(-) (limited to 'gdb/i386-linux-tdep.c') diff --git a/gdb/i386-linux-tdep.c b/gdb/i386-linux-tdep.c index 768a5b6a78b..da4c1e6af30 100644 --- a/gdb/i386-linux-tdep.c +++ b/gdb/i386-linux-tdep.c @@ -1,6 +1,6 @@ -/* Target-dependent code for GNU/Linux running on i386's, for GDB. +/* Target-dependent code for GNU/Linux i386. - Copyright 2000, 2001, 2002, 2003 Free Software Foundation, Inc. + Copyright 2000, 2001, 2002, 2003, 2004 Free Software Foundation, Inc.
