Original change's description: > [runtime] Remove extension slots from context objects > > Context objects have an extension slot, which contains further > additional data that depends on the type of the context. > > This CL removes the extension slot from contexts that don't need > them, hence reducing memory. > > The following contexts will still have an extension slot: native, > module, await, block and with contexts. See objects/contexts.h for > what the slot is used for. > The following contexts will not have an extension slot anymore (they > were not used before): script, catch and builtin contexts. > Eval and function contexts only have the extension slot if they > contain a sloppy eval. > > Bug: v8:9744 > Change-Id: I8ca56c22fa02437bbac392ea72174ebfca80e030 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1863191 > Commit-Queue: Victor Gomes <victorgomes@google.com> > Reviewed-by: Toon Verwaest <verwaest@chromium.org> > Reviewed-by: Jakob Gruber <jgruber@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Reviewed-by: Peter Marshall <petermarshall@chromium.org> > Auto-Submit: Victor Gomes <victorgomes@google.com> > Cr-Commit-Position: refs/heads/master@{#64372} TBR=verwaest@chromium.org,jgruber@chromium.org,ulan@chromium.org,leszeks@chromium.org,petermarshall@chromium.org Bug: v8:9744 Change-Id: I8700ed2fa62c89e86c39bb16ac3167f38ea8d63f Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1873695 Commit-Queue: Victor Gomes <victorgomes@chromium.org> Reviewed-by: Leszek Swirski <leszeks@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Reviewed-by: Peter Marshall <petermarshall@chromium.org> Cr-Commit-Position: refs/heads/master@{#64477}
