Sure:

$ git format-patch -1 2b2558bfacba3813863da6728c021eb89fa34677 && ~/Programming/gcc/contrib/mklog.py 00*
0001-Move-DWARF-constant-stringifying-code-to-new-file.patch

ChangeLog:

	* gdb/ChangeLog:
	* gdb/Makefile.in:
	* gdb/dwarf2/read.c (dwarf_tag_name):
	(dwarf_attr_name):
	(dwarf_form_name):
	(dwarf_bool_name):
	(dwarf_type_encoding_name):
	(dwarf_unknown):
	* gdb/dwarf2/stringify.c: New file.
	* gdb/dwarf2/stringify.h: New file.

Sure. You're a skilled GDB developer with long experience. But for newcomers or
