This gets all production code for Chrome building, excluding tests. There aren’t any guarantees that anything works yet. This is mostly a lot of CPU context shuffling. In contrast to macOS on x86, there’s no need to support 32-bit arm on macOS, because this new platform is 64-bit-only from its inception. Bug: crashpad:345 Change-Id: I187239b6a969005a3458af7fe30c44147a57f95f Reviewed-on: https://chromium-review.googlesource.com/c/crashpad/crashpad/+/2285961 Reviewed-by: Robert Sesek <rsesek@chromium.org> Commit-Queue: Mark Mentovai <mark@chromium.org>
