This is the V8 side of the implementation. You can take a look at a prototype of the Chrome side changes in https://crrev.com/c/1273043. Chrome could also use V8's default implementation of the trap handler, see https://crrev.com/c/1290952. Bug: v8:6743 Cq-Include-Trybots: luci.chromium.try:linux_chromium_rel_ng Change-Id: I9bb3e717db17a4f30bbb8acfd80a1f6510d463ff Reviewed-on: https://chromium-review.googlesource.com/c/1283111 Commit-Queue: Andreas Haas <ahaas@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Cr-Commit-Position: refs/heads/master@{#57117}
