-Subject: [PATCH] Move 'is_regular_file' from common-utils.c to filestuff.c
-
-There is no reason for 'is_regular_file' to be in common-utils.c; it
-belongs to 'filestuff.c'.  This commit moves the function definition
-and its prototype to the appropriate files.
-
-The motivation behind this move is a failure that happens on certain
-cross-compilation environments when compiling the IPA library, due to
-the way gnulib probes the need for a 'stat' call replacement.  Because
-configure checks when cross-compiling are more limited, gnulib decides
-that it needs to substitute the 'stat' calls its own 'rpl_stat';
-however, the IPA library doesn't link with gnulib, which leads to an
-error when compiling 'common-utils.c':

-More details can also be found at:

-  https://sourceware.org/ml/gdb-patches/2018-09/msg00304.html
-
-The most simple fix for this problem is to move 'is_regular_file' to
-'filestuff.c', which is not used by IPA.  This ends up making the
-files more logically organized as well, since 'is_regular_file' is a
-file operation.
-
-No regressions found.
