This optimization can be enabled when it's not possible to use the
managed linker (e.g. **Don't link**) or when the managed linker cannot
remove references to deprecated types that would cause an application
to be rejected by Apple.
References to the existing types will be renamed, e.g. `UIWebView` to
`DeprecatedWebView`, in every assemblies.
The type definition is also renamed (for validity) and all custom
attributes on the types and their members will be removed.
Code inside the members will be replaced with a
`throw new NotSupportedException ();`.
The msbuild test app `MyReleaseBuild` has been updated to test that the
optimization is working as expected (device builds are slow so reusing
this test has little impact in test time).
Basically the test ensure that `UIWebView` is used and cannot be removed
by the compiler (optimization) or the managed linker (since it's
referenced). Since the optimization is enabled then we can `grep` then
final `.app` directory to ensure there's no mention of `UIWebView` inside
any of the files that would be submitted.
The application can be run, by itself, and will turn green if OK, red if
`DeprecatedWebView` can't be found (skeleton replacement for `UIWebView`)
or orange if a `NotSupportedException` is thrown.
Finally introspection tests have been updated to skip over the deprecated
(and renamed) types. It should not be an issue right now, since this
optimization is not enabled by default, but it made testing easier.
Keep 'CallContextSecurityData' around since it's quite small (and the
normal linker logic will be able to deal with it if unused) and allows
the use of `Thread.CurrentPrincipal`
Also add unit test.
Fix https://github.com/xamarin/xamarin-macios/issues/7321
This allows mtouch to give better error message when something unexpected
occurs in the linker pipeline (at least for the sub-steps).
Practically it means fewer, contextless MT2001 errors. The replacements
error code are more precise, e.g.
* what was being done;
* what was being processed
and helps both diagnosing and, possibly, gives clues for workarounds
* Bump [watch-]mono to master to get fix for #43658.
https://bugzilla.xamarin.com/show_bug.cgi?id=43658
* [mtouch/mmp] Fix build after breaking cecil update in mono.
Also use mono's cecil instead of our own cecil submodule for mtouch.
* Bump [watch-]mono to get compilation fixes after cecil bump in mono.
* Remove cecil submodule, we only use the one in mono now.
