This is a reland of 36a7cba2 Unchanged, so: tbr=clemensb@chromium.org Original change's description: > Reland "[wasm][liftoff] Respect CallDescriptor linkage" > > This is a reland of 94283811 > > Patchset #2 fixes the Arm bug. A vpush is used to push the slot, > so subtract kSimd128Size from the stack decrement to get padding. > > Original change's description: > > [wasm][liftoff] Respect CallDescriptor linkage > > > > - Adds the actual stack slot location to LiftoffStackSlots::Slot. > > - Adds SortInPushedOrder method for architectures that push > > parameters. > > - Changes the LiftoffStackSlots::Construct signature to take the > > number of parameter slots in total, and changes implementations > > to insert padding when slots aren't contiguous. > > - Changes Arm MacroAssembler::AllocateStackSpace to check the > > immediate value, and to be a nop when it's zero. > > > > Bug: v8:9198 > > Change-Id: Ibd5775dbed3a40051fa9e345556231a1c07cf4e9 > > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2717120 > > Reviewed-by: Andreas Haas <ahaas@chromium.org> > > Reviewed-by: Clemens Backes <clemensb@chromium.org> > > Commit-Queue: Bill Budge <bbudge@chromium.org> > > Cr-Commit-Position: refs/heads/master@{#73191} > > Bug: v8:9198 > Change-Id: Iae4930e28dd7fc634e3709a5726379c6b37e5195 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2735984 > Reviewed-by: Bill Budge <bbudge@chromium.org> > Reviewed-by: Clemens Backes <clemensb@chromium.org> > Reviewed-by: Andreas Haas <ahaas@chromium.org> > Commit-Queue: Bill Budge <bbudge@chromium.org> > Cr-Commit-Position: refs/heads/master@{#73195} Bug: v8:9198 Change-Id: I45c2b6fc8c38ef864a0bd7a7be5b431c7b8855a3 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2739737 Commit-Queue: Bill Budge <bbudge@chromium.org> Reviewed-by: Clemens Backes <clemensb@chromium.org> Reviewed-by: Andreas Haas <ahaas@chromium.org> Cr-Commit-Position: refs/heads/master@{#73235}
