We really should get someone who has an AppleID to check what the support period is because if Apple don't care about Xcode9 anymore I doubt we should.

The page at https://docs.travis-ci.com/user/reference/osx/ has a nice list which Xcode versions are used with which macOS versions. Xcode10 was also available for macOS 10.13 (which is likely the oldest macOS version that we care about), so I think we can assume that macOS users that are still using 10.13 can upgrade to xcode10.1 if they want to compile QEMU.

Such support is present almost everywhere, except for Xcode 9. It is added in Xcode 10, but travis uses xcode9 by default, so we should support it for a while yet. Signed-off-by: Richard Henderson <richard.henderson@linaro.org> --- configure | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+)
