This reverts commit1feadfe81b. Reason for revert: Reland as bot stayed red after revert. Original change's description: > Revert "[cctest] Clarify that tests for sync instructions are simulator specific" > > This reverts commit4013518fe3. > > Reason for revert: > https://build.chromium.org/p/client.v8.ports/builders/V8%20Linux%20-%20arm64%20-%20sim%20-%20gc%20stress > > Original change's description: > > [cctest] Clarify that tests for sync instructions are simulator specific > > > > Some tests were recently added to test-simulator-arm.cc, however this file is > > meant for tests that are specific to the simulator and therefore are not written > > to work on hardware. While this sounds surprising, the reason is that our simulation > > of synchronisation instructions is more conservative than on hardware. > > > > To make this more clear, this patch renames the "test-simulator-arm{,64}.cc" > > files to "test-sync-primitives-arm{,64}.cc", and moves the vneg and vabs tests > > into "test-assembler-arm.cc" which is were tests that are garanteed to work in > > either native or simulated environments live. > > > > Finally, take the opportunity to share a little bit of code. > > > > Bug: v8:6963 > > Change-Id: Ifb85d3671c823b9bba73d09f419536b089a4e87c > > Reviewed-on: https://chromium-review.googlesource.com/749387 > > Reviewed-by: Clemens Hammacher <clemensh@chromium.org> > > Commit-Queue: Pierre Langlois <pierre.langlois@arm.com> > > Cr-Commit-Position: refs/heads/master@{#49073} > > TBR=clemensh@chromium.org,pierre.langlois@arm.com,bmeurer@chromium.org > > Change-Id: I1bfb4e9c7c18b716f417a84b18a14cb2e1fa3a7a > No-Presubmit: true > No-Tree-Checks: true > No-Try: true > Bug: v8:6963 > Reviewed-on: https://chromium-review.googlesource.com/750624 > Reviewed-by: Michael Achenbach <machenbach@chromium.org> > Commit-Queue: Michael Achenbach <machenbach@chromium.org> > Cr-Commit-Position: refs/heads/master@{#49074} TBR=machenbach@chromium.org,clemensh@chromium.org,pierre.langlois@arm.com,bmeurer@chromium.org Change-Id: I5af7bd3678758130534730a2f6f0b651b64c6956 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:6963 Reviewed-on: https://chromium-review.googlesource.com/750903 Reviewed-by: Michael Achenbach <machenbach@chromium.org> Commit-Queue: Michael Achenbach <machenbach@chromium.org> Cr-Commit-Position: refs/heads/master@{#49075}
