Reland "[liftoff][arm64] Zero-extend offsets also for SIMD"
This is a reland of b99fe75c. The test is now skipped on non-SIMD hardware. Original change's description: > [liftoff][arm64] Zero-extend offsets also for SIMD > > This extends https://crrev.com/c/2917612 also for SIMD, which > (sometimes) uses the special {GetMemOpWithImmOffsetZero} method. > As part of this CL, that method is renamed to {GetEffectiveAddress} > which IMO is a better name. Also, it just returns a register to make the > semantic of that function obvious in the signature. > > Drive-by: When sign extending to 32 bit, only write to the W portion of > the register. This is a bit cleaner, and I first thought that > this would be the bug. > > R=jkummerow@chromium.org > CC=thibaudm@chromium.org > > Bug: chromium:1231950, v8:12018 > Change-Id: Ifaefe1f18e3a00534a30c99e3c37ed09d9508f6e > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3049073 > Reviewed-by: Zhi An Ng <zhin@chromium.org> > Commit-Queue: Clemens Backes <clemensb@chromium.org> > Cr-Commit-Position: refs/heads/master@{#75898} TBR=zhin@chromium.org CC=jkummerow@chromium.org, thibaudm@chromium.org Bug: chromium:1231950, v8:12018 Change-Id: I662b62fafe99389be7a6c23b970fdf3768f866cf Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3051610Reviewed-by: Clemens Backes <clemensb@chromium.org> Commit-Queue: Clemens Backes <clemensb@chromium.org> Cr-Commit-Position: refs/heads/master@{#75901}
