([PATCH v4 00/43] Mirror map JIT memory for TCG)
These set of changes brings QEMU TCG to iOS devices and future Apple Silicon
devices. They were originally developed last year and have been working in the
UTM app. Recently, we ported the changes to master, re-wrote a lot of the build
script changes for meson, and broke up the patches into more distinct units.
A summary of the changes:
* `CONFIG_IOS` defined when building for iOS and iOS specific changes (as well
as unsupported code) are gated behind it.
* A new dependency, libucontext is added since iOS does not have native ucontext
and broken support for sigaltstack. libucontext is available as a new option
for coroutine backend.
Since v6:
* Dropped the Apple Silicon JIT support patch (superseded by another patchset)
* Changed libucontext to be a Meson subproject
* Cache availablity check for preadv/pwritev on macOS 11 and iOS 14
Since v5:
* Fixed some more instances of QAPI define of CONFIG_HOST_BLOCK_DEVICE
* Fixed libucontext build on newer version of GCC
Since v4:
* Updated QAPI schema for CONFIG_HOST_BLOCK_DEVICE
* Updated maintainers file for iOS host support
* Moved system() changes to osdep.h
* Fixed typo in libucontext meson.build change
Since v3:
* Moved mirror JIT support to a different patch set.
* Removed dependency on `pthread_jit_write_protect_np` because it was redundent
and also crashes if called on a non-jailbroken iOS device.
* Removed `--enable-cross-compile` option
* Fixed checkpatch errors
* Fixed iOS build on master due to new test recently added which calls system()
Since v2:
* Changed getting mirror pointer from a macro to inline functions
* Split constification of TCG code pointers to separate patch
* Removed slirp updates (will send future patch once slirp changes are in)
* Removed shared library patch (will send future patch)
