From 32a8097ba5dd6ddb71c0fb2fccbac262c371846a Mon Sep 17 00:00:00 2001 From: Pedro Alves Date: Fri, 17 Oct 2014 11:18:59 +0100 Subject: Delete Tru64 support This commit does most of the mechanical removal. IOW, the easy part. procfs.c isn't touched beyond removing a couple obvious bits that are guarded by a couple macros defined in config/alpha/nm-osf3.h. Going beyond that for procfs.c & co would be a harder excision that potentially affects Solaris. Some comments in the generic alpha code ABIs that may still be relevant and I wouldn't know what to do with them. That can always be done on a separate pass, preferably by someone who can test on alpha. A couple other spots have references to OSF/Tru64 and related files being removed, but it felt like removing them would make things worse, not better. We can revisit those when we next need to touch that code. I didn't remove a reference to osf in testsuite/lib/future.exp, as I believe that code is imported from DejaGNU. Built and tested on x86_64 Fedora 20, with --enable-targets=all. Tested that building for --target=alpha-osf3 on x86_64 Fedora 20 fails with: checking for default auto-load directory... $debugdir:$datadir/auto-load checking for default auto-load safe-path... $debugdir:$datadir/auto-load *** Configuration alpha-unknown-osf3 is obsolete. *** Support has been REMOVED. make[1]: *** [configure-gdb] Error 1 make[1]: Leaving directory `build-osf' make: *** [all] Error 2 gdb/ 2014-10-17 Pedro Alves * Makefile.in (ALL_64_TARGET_OBS): Remove alpha-osf1-tdep.o.
