Zichang Guo 162d6c5634 Revert "[vm] Add support for real unboxed floating point fields in AOT" This reverts commit `9eb531bde4`. Reason for revert: Bots are red. Some tests are failing. https://ci.chromium.org/p/dart/builders/ci.sandbox/vm-kernel-precomp-obfuscate-linux-release-x64/6039 https://ci.chromium.org/p/dart/builders/ci.sandbox/vm-kernel-precomp-android-release-arm_x64/957 Original change's description: > [vm] Add support for real unboxed floating point fields in AOT > > Non-nullable floating point fields (double, Float32x4, Float64x2) > are fully unboxed in their classes. > > A bitmap for each class was added to the shared class table in order to keep > track of the pointers of the classes. Since all classes in Flutter Gallery > have less than 64 fields, the bitmap is represented by a 64 bit integer and > fields whose offset is more than 64 words are not unboxed. > > The instance sizes and field offsets might change between target and host > in cross-compilation, since the number of words used to store unboxed fields > may differ. > > dart-aot Xeon > > SplayLatency -4.62% > SplayHarderLatency -4.17% > NavierStokes -2.20% > Tracer 8.72% > ParticleSystemPaint 2.90% > NBodySIMD 8.35% > NBody 25.59% > > With hack TFA to make doubles in Rect/Offset/Size classes in flutter non-nullable: > > flutter arm-v8: > > gallery total size: -1% > > matrix_utils_transform_rect_perspective -16.70% (less is better) > matrix_utils_transform_rect_affine -31.82% (less is better) > matrix_utils_transform_point_perspective -24.90% (less is better) > matrix_utils_transform_point_affine) -27.26% (less is better) > rrect_contains_bench -4.719% (less is better) > > Change-Id: I9ae09c9c3167d99f9efd071a92937aa51093fd1d > Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/131824 > Commit-Queue: Victor Agnez Lima <victoragnez@google.com> > Reviewed-by: Martin Kustermann <kustermann@google.com> > Reviewed-by: Ryan Macnak <rmacnak@google.com> > Reviewed-by: Samir Jindel <sjindel@google.com> TBR=kustermann@google.com,rmacnak@google.com,sjindel@google.com,victoragnez@google.com Change-Id: Ic73858f6adb7f55c4129d4f46ff4731b378cb634 No-Presubmit: true No-Tree-Checks: true No-Try: true Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/134020 Reviewed-by: Zichang Guo <zichangguo@google.com> Commit-Queue: Zichang Guo <zichangguo@google.com>		2020-01-30 18:13:28 +00:00
