From 898be3e0415c6d614395c087ef1e91210797cda7 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 21 Mar 2017 14:31:57 +0000 Subject: [PATCH] configure: Warn about deprecated hosts We plan to drop support in a future QEMU release for host OSes and host architectures for which we have no test machine where we can build and run tests. For the 2.9 release, make configure print a warning if it is run on such a host, so that the user has some warning of the plans and can volunteer to help us maintain the port if they need it to continue to function. This commit flags up as deprecated the CPU architectures: * ia64 * sparc * anything which we don't have a TCG port for (and which was presumably using TCI) and the OSes: * GNU/kFreeBSD * DragonFly BSD * NetBSD * OpenBSD * Solaris * AIX * Haiku It also makes entirely unrecognized host OS strings be rejected rather than treated as if they were Linux (which likely never worked).
