I just committed this patch:

2019-07-09  Michael Meissner  <meissner@linux.ibm.com>

	* config/rs6000/rs6000-internal.h (create_TOC_reference): Delete.
	* config/rs6000/rs6000-logue.c (create_TOC_reference): Move
	function from rs6000-logue.c back to rs6000.c.
	* config/rs6000/rs6000.c (create_TOC_reference): Likewise.
