This reverts commitc7c47c68f2. Reason for revert: breaks TSAN https://ci.chromium.org/p/v8/builders/ci/V8%20Linux64%20TSAN/28738 Original change's description: > Reland "[runtime] Move Context::native_context to the map" > > This is a reland off05bae1e0d> > Previously I presumed that the context read from a frame in the profiler was > a valid context. Turns out that on non-intel we're not guaranteed that the > frame is properly set up. In the case we looked at, the profiler took a > sample right before writing the frame marker indicating a builtin frame, > causing the "context" pointer from that frame to be a bytecode array. Since > we'll read random garbage on the stack as a possible context pointer, I made > the code reading the native context from it a little more defensive. > > Bug: v8:9860 > > Original change's description: > > [runtime] Move Context::native_context to the map > > > > Remove the native context slot from contexts by making context maps > > native-context-specific. Now we require 2 loads to go from a context to the > > native context, but we have 1 field fewer to store when creating contexts. > > > > Change-Id: I3c0d7c50c94060c4129db684f46a567de6f30e8d > > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1859629 > > Commit-Queue: Toon Verwaest <verwaest@chromium.org> > > Reviewed-by: Igor Sheludko <ishell@chromium.org> > > Reviewed-by: Peter Marshall <petermarshall@chromium.org> > > Reviewed-by: Maya Lekova <mslekova@chromium.org> > > Reviewed-by: Georg Neis <neis@chromium.org> > > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > > Reviewed-by: Toon Verwaest <verwaest@chromium.org> > > Cr-Commit-Position: refs/heads/master@{#64296} > > Change-Id: If9461e9b21d35a260d71c79d7f95e518cc429e09 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1864930 > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Peter Marshall <petermarshall@chromium.org> > Reviewed-by: Igor Sheludko <ishell@chromium.org> > Reviewed-by: Georg Neis <neis@chromium.org> > Commit-Queue: Toon Verwaest <verwaest@chromium.org> > Auto-Submit: Toon Verwaest <verwaest@chromium.org> > Cr-Commit-Position: refs/heads/master@{#64314} TBR=ulan@chromium.org,neis@chromium.org,petermarshall@chromium.org,ishell@chromium.org,verwaest@chromium.org,mslekova@chromium.org,victorgomes@google.com Change-Id: I4f9edc62ea6f9f5857619ff0ad1a63cab4b33cc3 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:9860 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1864937 Reviewed-by: Sathya Gunasekaran <gsathya@chromium.org> Commit-Queue: Sathya Gunasekaran <gsathya@chromium.org> Cr-Commit-Position: refs/heads/master@{#64316}
