; Order segments alphabetically.
; Rather ugly workaround to prevent the automatically generated code segment
; for the large model (filename_TEXT) from enforcing its word alignment
; between _TEXT and the first code segment even though we never emit anything
; into it.
; However, this merely pushes filename_TEXT before _TEXTC, and therefore
; breaks another group of files. In these, we actually have to rename that
; automatically generated code segment to one that is expected to have word
; alignment.
