'is' tests against record types are split into series of 'is' tests of record fields. This is more efficient as record instances cannot be added to subtype test caches (because type of a record instance depends on types of its fields). This change also adds canonicalization and constant evaluation of LoadFieldInstr for record fields. Performance on a trivial micro-benchmark (on x64): JIT (RunTime): 4519104.5 -> 20031.5 AOT (RunTime): 4352583.0 -> 26281.6 TEST=ci Issue: https://github.com/dart-lang/sdk/issues/49719 Change-Id: I2ed464cd3b31f365b17805f4e7debe1d6d1051fa Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/268080 Reviewed-by: Ryan Macnak <rmacnak@google.com> Reviewed-by: Slava Egorov <vegorov@google.com> Commit-Queue: Alexander Markov <alexmarkov@google.com> |
