+
+ Merge from mainline.
+ 2002-03-21 Albert Chin-A-Young <china@thewrittenword.com>
+ * genscripts.sh (LIB_SEARCH_DIRS): Quote path.
+
+ 2002-03-20 Alan Modra <amodra@bigpond.net.au>
+ * ldlang.c (ldlang_add_undef): If the output bfd has been opened,
+ add the symbol to the linker hash table immediately.
+ (lang_place_undefineds): Split symbol creation out..
+ (insert_undefined): ..to here.
+
+ 2002-03-18 Alan Modra <amodra@bigpond.net.au>
+ * ldmain.c (main): Move .text readonly flag fudges from here..
+ * ldlang.c (lang_process): ..to here.
+
+ 2002-03-14 Alan Modra <amodra@bigpond.net.au>
+ * ldlang.c (lang_check): Remove the word size check added in last
+ change. Treat emitrelocations case as for relocatable links.
+
+ 2002-03-13 Alan Modra <amodra@bigpond.net.au>
+ * ldlang.c (lang_check): Do relocatable link checks first, so that
+ warn_mismatch can't override. Check compatible and word size too.
+
+ 2002-03-04 H.J. Lu <hjl@gnu.org>
+ * scripttempl/elf.sc: Put .preinit_array, .init_array and
+ .fini_array in the data segment.
+
+ 2002-03-04 Alan Modra <amodra@bigpond.net.au>
+ * scripttempl/elf.sc: Correct syntax errors in 2002-03-01 commit.
+
+ 2002-03-01 David Mosberger <davidm@hpl.hp.com>
+ * scripttempl/elf.sc (SECTIONS): Add entries for .preinit_array,
+ .init_array, and .fini_array.

2002-03-18 David O'Brien <obrien@FreeBSD.org>
* emultempl/elf32.em: Use lbasename vs. basename to fix problem where
