* Enable flutter engine to also work with .*so files on android
We would like to be able to use native tools (e.g. simpleperf, gdb) with
precompiled flutter apps. The native tools work much better with *.so
files instead of the custom formats the Dart VM uses by default.
This CL adds support for being able to load the flutter app from an *.so
file on Android.
* Add sanity check to ensure we have either shared library or instruction snapshot (but not both)
With the update to HEAD of the Fuchsia buildtools repo, the new clang
toolchain picked up caused link-time breakage in android x86_64
libFlutter.so builds.
Sample log:
https://build.chromium.org/p/client.flutter/builders/Linux%20Engine/builds/1974/steps/build%20android_debug_x64/logs/stdio
Sample failure:
FAILED: libflutter.so libflutter.so.TOC lib.stripped/libflutter.so
../../third_party/android_tools/ndk/toolchains/x86_64-4.9/prebuilt/linux-x86_64/lib/gcc/x86_64-linux-android/4.9.x/../../../../x86_64-linux-android/bin/ld.gold: error: obj/flutter/shell/platform/android/libflutter/android_context_gl.o: unsupported reloc 42 against global symbol std::__ndk1::num_put<char, std::__ndk1::ostreambuf_iterator<char, std::__ndk1::char_traits<char> > >::id
This reverts commit 8ad42f0dae.
* Roll Fuchsia buildtools to 85907c59e97527d79bbfdfd849d8e85c24959cc5
This also updates Flutter buildroot to a6e52dbb776c45cc8c57d7143b8eb8b2e762fdfb
which disables -Wtautological-constant-compare temporarily until
https://reviews.llvm.org/D39462 lands in clang. This is in line with
Fuchsia's compiler options.
* Apply clang-format diffs
No logical changes. This applies clang-format from the latest Fuchsia
buildtools to the engine codebase.
* Read core platform kernel file during Dart initialization.
Currently service isolate is initialized from the source code parsed by VM.
This CL changes it so service isolate created during Dart initialization
is created from the kernel platform.dill file if it is present in the application
bundle. Then this platform kernel file is kept in dart_init module and reused
for application sciprt isolates.
* Reformat and merge
* Use accessor method
* Avoid passing running_from_kernel param. Add TODO for cleanup. Rename param.
- Assumes only the Dart VM is interested in idle notification.
- Gives the VM the time remaining in each frame.
- Gives the VM 100ms if there is no pending frame.
Issue flutter/flutter#9594
* Fix Flutter loading from dill files.
* Remove disable of causal async stacks.
* Include mirrors patch files as they are needed for release/profile gen_snapshot
* Free the bytes
* Add FTL_DCHECK
