Tested on x86_64-suse-linux, applied on the mainline.


2019-10-11  Eric Botcazou  <ebotcazou@adacore.com>

	* gcc-interface/decl.c (elaborate_reference_1): Specifically deal with
	pointer displacement.

	* gcc-interface/decl.c (components_to_record): Use proper name.

	* gcc-interface/trans.c (Sloc_to_locus): Use standard types.
