+	* config/tc-hppa.c (pa_build_unwind_subspace): SEC_ALLOC should
+	not be on for .hppa_unwind.
+	(md_pseudo_table): .PARAM and .param are valid pseudo-ops for GAS.
+	(pa_param): New function to handle .PARAM directives.

+	functions.  Handle '|' for movb; allow movb,n.
+	(pa_parse_nonneg_cmpsub_cmpltr): Delete old useless
+	version.  Handle cases where no completer exists for
+	comb,n or addb,n.
+	(pa_parse_neg_cmpsub_cmpltr): Handle cases where no 
+	completer exists for comb,n or addb,n.  Make logic
+	mirror that of pa_parse_nonneg_cmpsub_cmpltr.

+	(obj_elf_version): A .note section shouldn't have the SEC_ALLOC
+	attribute.
+
+	* config/tc-hppa.c (hppa_tc_make_sections): Add some processing to
+	handle symbol extension sections.
+
