This reverts commit b66993bc. Reason for revert: Broke v8 win32 https://ci.chromium.org/p/v8/builders/ci/V8%20Win32/29454? Original change's description: > [code] Separate instruction and metadata areas > > In this CL, Code object layout changes s.t. the instruction > area is distinct / non-overlapping from the metadata area. > > On-heap Code objects now have a variable-size `body` area, > containing distinct-but-adjacent `instruction` and `metadata` > areas. > > Off-heap code (= embedded builtins) currently have the same, > but in the future the metadata area will move elsewhere and > no longer be adjacent to instructions. > > To implement this, the main changes are: > > - The Code object header now contains instruction and metadata > sizes, and no longer contains the safepoint table offset > (it's implicitly the first table of the metadata section). > - The embedded metadata table contains information about both > instruction and metadata areas. > > I've also added assertions in spots that currently rely on a > contiguous body area. > > Bug: v8:11036 > Change-Id: I940f0c70c07ad511dafd2d2c3e337de8c92cd4b9 > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2491025 > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Reviewed-by: Clemens Backes <clemensb@chromium.org> > Reviewed-by: Dominik Inführ <dinfuehr@chromium.org> > Commit-Queue: Jakob Gruber <jgruber@chromium.org> > Cr-Commit-Position: refs/heads/master@{#70743} TBR=jgruber@chromium.org,leszeks@chromium.org,clemensb@chromium.org,dinfuehr@chromium.org Change-Id: Ia52ac609a47b8a2038a2511f0af8526ebdfe4719 No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:11036 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2497381Reviewed-by: Zhi An Ng <zhin@chromium.org> Commit-Queue: Zhi An Ng <zhin@chromium.org> Cr-Commit-Position: refs/heads/master@{#70744}
