HWASAN tags stack regions (and stack pointers) with 0, but also selectively tags some stack allocations with non-zero tags. These tags need to be cleared when allocation goes out of scope so that stack can be later safely reused - otherwise stale tags confuse HWASAN instrumentation later. This CL teaches Exceptions::JumpToFrame to do that. CL also adds basic build changes to support building with HWASAN, though I don't wire it into CI for now as it can only really run on Android ARM64 TEST=manually on Android phone and on internal tests Bug: b/374433249 Change-Id: I678443dc1de693c999a226bee0d71a6f3582d4f9 Reviewed-on: https://dart-review.googlesource.com/c/sdk/+/421180 Commit-Queue: Ryan Macnak <rmacnak@google.com> Reviewed-by: Ryan Macnak <rmacnak@google.com> Auto-Submit: Slava Egorov <vegorov@google.com>
This directory was taken from a snapshot of flutter/engine/src/build/.
The snapshot was taken with a recursive copy cp -R of the directory from
the flutter repository.
The contents has now diverged significantly from Flutter, and is maintained independently by the Dart team. It is used to support the GN build system.
