From 03b62bbbce3dc5f15131d9e78f77d035cd1cffb3 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Tue, 22 Nov 2016 16:14:24 -0500 Subject: Normalize names of some source files Most tdep/nat files are named: --tdep.c --nat.c A few files do not respect this scheme. This patch renames them so that they are consistent with the rest of the files. It builds fine with --enable-targets=all, but that doesn't test the nat files. I can only hope that my grep skill is good enough. gdb/ChangeLog: * Makefile.in (ALL_64_TARGET_OBS, ALL_TARGET_OBS, HFILES_NO_SRCDIR, ALLDEPFILES): Rename files. * alphabsd-nat.c: Rename to ... *
