In order to have instance calls with unboxed parameters, all the possible targets need to be able to those parameters unboxed. Then, the methods were partitioned according to the class hierarchy, and the inferred types from TFA are used to determine the parameters that could be unboxed. This is done for non-nullable integer and double parameters, and return value. dart-aot linux x64: Bench2D 8.028% DeltaBlue 4.688% ParticleSystemPaint 27.79% Flutter release android-armv8: velocity_tracker_bench -2.026% (less is better) flutter_gallery_total_size -0.1460% flutter_gallery_instructions_size -0.2715% flutter_gallery_readonlydata_size 0.0539% Issue https://github.com/dart-lang/sdk/issues/33549 Change-Id: Iedd9b4321c3d78b406ea1708e15c747754433027 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/138501 Commit-Queue: Victor Agnez Lima <victoragnez@google.com> Reviewed-by: Martin Kustermann <kustermann@google.com> Reviewed-by: Samir Jindel <sjindel@google.com>
