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` and `CONFIG_IOS_JIT` 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. * On stock iOS devices, there is a workaround for running JIT code without any special entitlement. It requires the JIT region to be mirror mapped with one region RW and another one RX. To support this style of JIT, TCG is changed to support writing to a different code_ptr. These changes are gated by the `CONFIG_IOS_JIT`. * For (recent) jailbroken iOS devices as well as upcoming Apple Silicon devices, there are new rules for applications supporting JIT (with the proper entitlement). These rules are implemented as well. 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) -j osy (9): configure: option to disable host block devices configure: cross-compiling without cross_prefix qemu: add support for iOS host coroutine: add libucontext as external library tcg: add const hints for code pointers tcg: implement mirror mapped JIT for iOS tcg: mirror mapping RWX pages for iOS optional tcg: support JIT on Apple Silicon block: check availablity for preadv/pwritev on mac docs/devel/ios.rst | 40 +++++++++ configure | 104 ++++++++++++++++++++-- meson.build | 32 ++++++- include/exec/exec-all.h | 10 +++ include/sysemu/tcg.h | 2 +- include/tcg/tcg-apple-jit.h | 85 ++++++++++++++++++ include/tcg/tcg.h | 28 +++++- tcg/aarch64/tcg-target.h | 23 ++++- tcg/arm/tcg-target.h | 9 +- tcg/i386/tcg-target.h | 24 ++++- tcg/mips/tcg-target.h | 8 +- tcg/ppc/tcg-target.h | 8 +- tcg/riscv/tcg-target.h | 9 +- tcg/s390/tcg-target.h | 13 ++- tcg/sparc/tcg-target.h | 8 +- tcg/tci/tcg-target.h | 9 +- accel/tcg/cpu-exec-common.c | 2 + accel/tcg/cpu-exec.c | 9 +- accel/tcg/tcg-all.c | 27 +++++- accel/tcg/translate-all.c | 168 ++++++++++++++++++++++++++++++++--- block.c | 2 +- block/file-posix.c | 50 ++++++++--- bsd-user/main.c | 2 +- linux-user/main.c | 2 +- net/slirp.c | 16 ++-- qga/commands-posix.c | 6 ++ target/arm/arm-semi.c | 2 + target/m68k/m68k-semi.c | 2 + target/nios2/nios2-semi.c | 2 + tcg/tcg.c | 64 ++++++++----- util/coroutine-ucontext.c | 9 ++ .gitmodules | 3 + libucontext | 1 + meson_options.txt | 2 + qemu-options.hx | 11 +++ tcg/aarch64/tcg-target.c.inc | 48 ++++++---- tcg/arm/tcg-target.c.inc | 33 ++++--- tcg/i386/tcg-target.c.inc | 28 +++--- tcg/mips/tcg-target.c.inc | 64 +++++++------ tcg/ppc/tcg-target.c.inc | 55 +++++++----- tcg/riscv/tcg-target.c.inc | 51 ++++++----- tcg/s390/tcg-target.c.inc | 25 +++--- tcg/sparc/tcg-target.c.inc | 33 ++++--- tcg/tcg-ldst.c.inc | 2 +- tcg/tcg-pool.c.inc | 9 +- tcg/tci/tcg-target.c.inc | 8 +- tests/qtest/meson.build | 7 +- 47 files changed, 919 insertions(+), 236 deletions(-) create mode 100644 docs/devel/ios.rst create mode 100644 include/tcg/tcg-apple-jit.h create mode 160000 libucontext
