Swapnil Gaikwad ffa9f163e6 Reland "Update GetIterator bytecode to load and call object[Symbol.iterator]" ... This is a reland of 8b89a7c32d Reland after disabling the test getting deadlocked with '--gc_stress' flag. The CL was reverted because of the 'wasm/grow-shared-memory' test from the mjsunit test suite deadlocked for the 'gc_stress' variant. This is the known issue (v8:9221) and the deadlocking test is now disabled ( 1c8981e3f4). Original change's description: > Update GetIterator bytecode to load and call object[Symbol.iterator] > > The functionality of the GetIterator bytecode introduced previously is > now extended from loading the @@iterator property to calling the property > as well. This change basically absorbs the functionality of additional > two bytecodes - Star, CallProperty0 in the GetIterator bytecode. > Importantly, this change handles the cases of eager and lazy deoptimization > in the middle of the bytecode, i.e., lazy deopt for LdaNamedProperty and > eager deopt of the CallProperty0 bytecode, using the continuation builtins. > This mechanism can work as a template for the future bytecode that require > handling such inter-bytecode deopt scenario. The tests evaluating the eager > and lazy deopt scenarios are also included. > > Bug: v8:9489 > Change-Id: I93eb022bbc3d37582407820aa8482a343cac6c12 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1758313 > Commit-Queue: Swapnil Gaikwad <swapnilgaikwad@google.com> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Reviewed-by: Tobias Tebbi <tebbi@chromium.org> > Cr-Commit-Position: refs/heads/master@{#63528} Bug: v8:9489,v8:9221 Change-Id: I4286255aef457bfdbbe5eb50fc6dabdf9c0955b1 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1787427 Reviewed-by: Tobias Tebbi <tebbi@chromium.org> Reviewed-by: Leszek Swirski <leszeks@chromium.org> Commit-Queue: Swapnil Gaikwad <swapnilgaikwad@google.com> Cr-Commit-Position: refs/heads/master@{#63599}		2019-09-06 13:44:12 +00:00
