Alexey Kozyatinskiy 7101881269 Reland "[debug] introduced runtime side effect check" ... This is a reland of 7a2c371383 Original change's description: > [debug] introduced runtime side effect check > > This CL demonstrates minimum valuable addition to existing debug evaluate > without side effects mechanism. > With this CL user can evaluate expressions like: > [a,b] // create any kind of temporary array literals > [a,b].reduce((x,y) => x + y, 0); // use reduce method > [1,2,3].fill(2); // change temporary arrays > > The core idea: any change of the object created during evaluation without > side effects is side effect free. As soon as we try to store this temporary > object to object existed before evaluation we will terminate execution. > > Implementation: > - track all objects allocated during evaluation and mark them as temporary, > - patch all bytecodes which change objects. > > A little more details (including performance analysis): [1]. > > [1] https://docs.google.com/document/d/10qqAtZADspPnpYa6SEdYRxrddfKIZJIzbLtGpsZQkRo/edit# > > Bug: v8:7588 > Change-Id: I69f7b96e1ebd7ad0022219e8213211c7be72a111 > Reviewed-on: https://chromium-review.googlesource.com/972615 > Commit-Queue: Aleksey Kozyatinskiy <kozyatinskiy@chromium.org> > Reviewed-by: Yang Guo <yangguo@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Cr-Commit-Position: refs/heads/master@{#52370} Bug: v8:7588 Change-Id: Ibc92bf19155f2ddaedae39b0c576b994e84afcf8 Reviewed-on: https://chromium-review.googlesource.com/996760 Reviewed-by: Aleksey Kozyatinskiy <kozyatinskiy@chromium.org> Commit-Queue: Aleksey Kozyatinskiy <kozyatinskiy@chromium.org> Cr-Commit-Position: refs/heads/master@{#52373}		2018-04-05 03:36:10 +00:00
