Daco Harkes a7163dba81 [benchmarks/ffi] Add FfiStructCopy benchmark ... `_memCopy` inside `dart:ffi` is currently doing a per-byte copy in Dart. This is rather slow, we should optimize this with the `MemoryCopyInstr` in the VM. This CL adds benchmarks to report the number of bytes copied per second. Adds only benchmarks with copies of 32^(0..3), as non-power-of-two benchmarks did not seem to behave differently. Since legacy mode is no longer benchmarked, the dart2 version of this benchmark is omitted. Benchmarks set up according to https://dart-review.googlesource.com/c/sdk/+/200188 Bug: https://github.com/dart-lang/sdk/issues/43967 Change-Id: I3d9be8de725820fd3365a7dc85d15174bddc1ae6 Cq-Include-Trybots: luci.dart.try:benchmark-linux-try Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/277522 Reviewed-by: Jonas Termansen <sortie@google.com> Commit-Queue: Daco Harkes <dacoharkes@google.com>		2022-12-29 10:21:19 +00:00
