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). Signed-off-by: Peter Maydell Reviewed-by: Thomas Huth --- v2: mark FreeBSD as 'supported' as I have got a VM config going for it for build tests. NetBSD doesn't boot inside KVM (!), and OpenBSD I have got running but "make check" hangs where we try to run guest code. configure | 49 +++++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 47 insertions(+), 2 deletions(-) diff --git a/configure b/configure index 02e3b69..3291603 100755 --- a/configure +++ b/configure @@ -321,6 +321,9 @@ tcmalloc="no" jemalloc="no" replication="yes" +supported_cpu="no" +supported_os="no" + # parse CC options first for opt do optarg=$(expr "x$opt" : 'x[^=]*=\(.*\)') @@ -517,23 +520,32 @@ ARCH= # Normalise host CPU name and set ARCH. # Note that this case should only have supported host CPUs, not guests. case "$cpu" in - ia64|ppc|ppc64|s390|s390x|sparc64|x32) + ppc|ppc64|s390|s390x|x32) + cpu="$cpu" + supported_cpu="yes" + ;; + ia64|sparc64) cpu="$cpu" ;; i386|i486|i586|i686|i86pc|BePC) cpu="i386" + supported_cpu="yes" ;; x86_64|amd64) cpu="x86_64" + supported_cpu="yes" ;; armv*b|armv*l|arm) cpu="arm" + supported_cpu="yes" ;; aarch64) cpu="aarch64" + supported_cpu="yes" ;; mips*) cpu="mips" + supported_cpu="yes" ;; sparc|sun4[cdmuv]) cpu="sparc" @@ -562,6 +574,7 @@ MINGW32*) else audio_drv_list="" fi + supported_os="yes" ;; GNU/kFreeBSD) bsd="yes" @@ -579,6 +592,7 @@ FreeBSD) libs_qga="-lutil $libs_qga" netmap="" # enable netmap autodetect HOST_VARIANT_DIR="freebsd" + supported_os="yes" ;; DragonFly) bsd="yes" @@ -620,6 +634,7 @@ Darwin) # won't work when we're compiling with gcc as a C compiler.
