Revert "Reland "[builtins] Verify Isolate compatibility with the embedded blob"" This reverts commit 1e3582b5aecfeb0ffdca4bda3f1fd66d433236f6. Reason for revert: Still fails nosnap: https://ci.chromium.org/p/v8/builders/luci.v8.ci/V8%20Linux%20-%20nosnap%20-%20debug/22789 Original change's description: > Reland "[builtins] Verify Isolate compatibility with the embedded blob" > > This is a reland of b022e825bd9f45279bb0c493a9081804f17455ae > > Original change's description: > > [builtins] Verify Isolate compatibility with the embedded blob > > > > Embedded builtins (= the embedded blob) have a few dependencies on the > > snapshot state. For instance, they require that metadata stored on > > builtin Code objects as well as the builtins constant table remain > > unchanged from mksnapshot-time. Embedders may violate these > > assumptions by accident, e.g. by loading a snapshot generated with > > different build flags, leading to seemingly unrelated failures later > > on. > > > > This CL introduces an Isolate hash stored in the embedded blob which > > hashes relevant parts of builtin Code objects and the builtins > > constant table. It's verified in Isolate::Init in debug builds. > > > > Bug: v8:8723 > > Change-Id: Ifc9bdbe6f56ea67d8984f162afa73a3572cfbba8 > > Reviewed-on: https://chromium-review.googlesource.com/c/1442641 > > Commit-Queue: Jakob Gruber <jgruber@chromium.org> > > Reviewed-by: Sigurd Schneider <sigurds@chromium.org> > > Cr-Commit-Position: refs/heads/master@{#59177} > > Tbr: yangguo@chromium.org,sigurds@chromium.org > Bug: v8:8723 > Change-Id: I1dd001783f0f1fae21a9809c8639e40f55b8f663 > Reviewed-on: https://chromium-review.googlesource.com/c/1445985 > Commit-Queue: Jakob Gruber <jgruber@chromium.org> > Reviewed-by: Jakob Gruber <jgruber@chromium.org> > Reviewed-by: Sigurd Schneider <sigurds@chromium.org> > Cr-Commit-Position: refs/heads/master@{#59236} TBR=yangguo@chromium.org,sigurds@chromium.org,jgruber@chromium.org Change-Id: If6082452c739d4de44ed70d3c6355f5282684ac1 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:8723 Reviewed-on: https://chromium-review.googlesource.com/c/1448311 Reviewed-by: Clemens Hammacher <clemensh@chromium.org> Commit-Queue: Clemens Hammacher <clemensh@chromium.org> Cr-Commit-Position: refs/heads/master@{#59241}
