Daco Harkes 77dc74bcd5 [vm/ffi] Support packed Structs ... 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>		2021-03-19 15:34:42 +00:00
