commit 39865a7f420ab4ca4dec6ed27339618a5d5dc366
Author: Nick Clifton <nickc@redhat.com>
Date:   Wed Oct 11 16:48:16 2017 +0100

    Disable the inclusion of logical input files in the assembler listing output unless high level source listing has been enabled.
    
    	PR 21977
    	* listing.c (listing_newline): Use the name of the current
    	physical input file, rather than the current logical input file,
    	unless including high level source in the listing.
    	* input-scrub.c (as_where_physical): New function.  Returns the
    	name of the current physical input file.
    	* as.h: Add prototype for as_where_physical.
