         * ld-mips-elf/reloc-estimate-1.d: Make endian-neutral.
 
+2008-09-20  Jan Kratochvil  <jan.kratochvil@redhat.com>
+
+        Provide virtual target "cfi" for targets supporting CFI.
+        * ld-elf/eh-frame-hdr.d: Replace target and xfail statements by single
+        `target: cfi'.
+        * ld-elf/eh-group.exp: Call check_as_cfi instead of is_elf_format.
+        * ld-elf/eh-group1.s, elf/eh-group2.s: Use more compatible section
+        flags prefix '%'.
+        * ld-elf/eh5.d: Replace target statement by `target: cfi' with an Alpha
+        exception.  Relax the `Code alignment factor' matching.
+        * lib/ld-lib.exp: Rename istarget as istarget_ld.
+        (istarget, check_as_cfi): New procedure.
+        (run_dump_test): New comment for the virtual target `cfi'.
