X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=48ed10d312ee6a058964f1fa5c4f89fddb2fa2a2;p=thirdparty%2Fgcc.git

fortran: array descriptor: Move array growth function [PR122521]

Move gfc_grow_array, a descriptor growth function used in array constructor
descriptors initialisation, to trans-descriptor.cc.

	PR fortran/122521

gcc/fortran/ChangeLog:

	* trans-array.cc (gfc_grow_array): Move function ...
	* trans-descriptor.cc (gfc_grow_array): ... to this file.
	* trans-descriptor.h (gfc_grow_array): Add declaration.
