Closes: https://github.com/dart-lang/sdk/issues/38158 This CL implements unaligned access for float/double on arm32, but does not expose it in an API. Rather it only uses these loads/stores inside the getters and setters of packed structs. Bug: https://github.com/dart-lang/sdk/issues/45009 Besides unaligned access for float/double, this CL is mostly a CFE change. The only VM change is reading the packing in the `_FfiStructLayout` annotation. The implementation of using the packing in the VM, and analyzer changes have landed separately in earlier CLs. tools/test.py ffi ffi_2 TEST=tests/ffi(_2)/(.*)by_value_(*.)_test.dart Change-Id: Ic3106ecc626d2e30674a49bf03f65ae12d2b3502 Cq-Include-Trybots: luci.dart.try:dart-sdk-linux-try,dart-sdk-mac-try,dart-sdk-win-try,vm-ffi-android-debug-arm-try,vm-ffi-android-debug-arm64-try,vm-kernel-asan-linux-release-x64-try,vm-kernel-mac-debug-x64-try,vm-kernel-linux-debug-ia32-try,vm-kernel-linux-debug-x64-try,vm-kernel-nnbd-linux-debug-x64-try,vm-kernel-nnbd-linux-debug-ia32-try,vm-kernel-nnbd-mac-release-x64-try,vm-kernel-nnbd-win-debug-x64-try,vm-kernel-precomp-linux-debug-x64-try,vm-kernel-precomp-linux-debug-simarm_x64-try,vm-kernel-precomp-nnbd-linux-debug-x64-try,vm-kernel-precomp-win-release-x64-try,vm-kernel-reload-linux-debug-x64-try,vm-kernel-reload-rollback-linux-debug-x64-try,vm-kernel-win-debug-x64-try,vm-kernel-win-debug-ia32-try,vm-precomp-ffi-qemu-linux-release-arm-try,vm-kernel-precomp-obfuscate-linux-release-x64-try,vm-kernel-msan-linux-release-x64-try,vm-kernel-precomp-msan-linux-release-x64-try,vm-kernel-precomp-android-release-arm_x64-try,analyzer-analysis-server-linux-try Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/186143 Reviewed-by: Aske Simon Christensen <askesc@google.com>
FE/analyzer shared code
This package contains logic that is shared between the front_end and analyzer packages. It is intended solely to facilitate development of the Dart SDK, and is not intended for use by end users. In particular, this package has no public API, so no guarantee is made of compatibility between one version of the package and the next.
End users should consider using the analyzer package to analyze Dart source code.
