[PATCH] D34529: [Driver] Check that the iOS deployment target is iOS 10 or earlier if the target is 32-bit

[Akira Hatanaka via Phabricator via cfe-commits]

ahatanak created this revision.

The following changes are made to the driver since 32-bit apps do not run on iOS 11 or later:

- If the deployment target is set explicitly, either with a command-line option or an environment variable, the driver should report an error if the version is greater than iOS 10.

- In the case where the deployment target is not set explicitly and the default is inferred from the target triple or SDK version, it should use a maximum default of iOS 10.
