When developing most code changes, it is sufficient to test compilation with a single target - rebuilding all targets just extends compile times while not detecting any new problems. Developers will often thus specify a single target for configure, commonly matching the host architecture. eg ./configure --target-list=3Dx86_64-softmmu This works fine, but is a bit of a verbose thing to type out everytime configure is invoked. There are already short-hand args to disable all user targets, all softmmu targets, or all tcg targets. This adds one further shorthand to disable all non-native architecture targets. ./configure --native Signed-off-by: Daniel P. Berrang=C3=A9 --- Suggestions welcomed for better names than --native, but bear in mind the goal is to minimise amount of typing so nothing too verbose, hence why I didn't do something like --disable-non-native ... configure | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) diff --git a/configure b/configure index af72fc852e..807af93116 100755 --- a/configure +++ b/configure @@ -233,6 +233,22 @@ supported_whpx_target() { return 1 } =20 +supported_native_target() { + glob "$1" "*-softmmu" || return 1 + case "${1%-softmmu}:$cpu" in + arm:arm | aarch64:aarch64 | \ + i386:i386 | i386:x32 | \ + x86_64:x86_64 | \ + mips:mips | mipsel:mips | \ + ppc:ppc | ppcemb:ppc | \ + ppc64:ppc64 | \ + s390x:s390x) + return 0 + ;; + esac + return 1 +} + supported_target() { case "$1" in *-softmmu) @@ -254,6 +270,10 @@ supported_target() { return 1 ;; esac + if test "$native" =3D "yes" + then + supported_native_target "$1" || return 1 + fi test "$tcg" =3D "yes" && return 0 supported_kvm_target "$1" && return 0 supported_xen_target "$1" && return 0 @@ -390,6 +410,7 @@ cocoa=3D"no" softmmu=3D"yes" linux_user=3D"no" bsd_user=3D"no" +native=3D"no" blobs=3D"yes" pkgversion=3D"" pie=3D"" @@ -1112,6 +1133,8 @@ for opt do cocoa=3D"yes" ; audio_drv_list=3D"coreaudio $(echo $audio_drv_list | sed s,coreaud= io,,g)" ;; + --native) native=3D"yes" + ;; --disable-system) softmmu=3D"no" ;; --enable-system) softmmu=3D"yes" @@ -1540,6 +1563,7 @@ Advanced options (experts only): xen pv domain builder --enable-debug-stack-usage track the maximum stack usage of stacks creat= ed by qemu_alloc_stack + --native only enable the softmmu target matching host = architecture =20 Optional features, enabled with --enable-FEATURE and disabled with --disable-FEATURE, default is enabled if available: --=20 2.14.3
