+Subject: [PATCH] PR 33452 SEGV in bfd_elf_gc_record_vtentry
+
+Limit addends on vtentry relocs, otherwise ld might attempt to
+allocate a stupidly large array.  This also fixes the expression
+overflow leading to pr33452.  A vtable of 33M entries on a 64-bit
+host is surely large enough, especially considering that VTINHERIT
+and VTENTRY relocations are to support -fvtable-gc that disappeared
+from gcc over 20 years ago.

+Subject: [PATCH] elf: Return error on unsorted symbol table if not allowed
+
+Normally ELF symbol table should be sorted, i.e., local symbols precede
+global symbols.  Irix 6 is an exception and its elf_bad_symtab is set
+to true.  Issue an error if elf_bad_symtab is false and symbol table is
+unsorted.
+
+	PR ld/33450
+	* elflink.c (set_symbol_value): Change return type to bool and
+	return false on error.  Issue an error on unsorted symbol table
+	if not allowed.
+	(elf_link_input_bfd): Return false if set_symbol_value reurns
+	false.
