Was this an intentional change in V8 and it's guaranteed to always be the case now? If you don't know this for sure, we should check with them first...

I checked with them, yangguo@ (cc-ed) confirmed.

OK, great! We can just remove the per-architecture generation and special-casing so that it goes back to just having the same name on both, and then the APK merging script will verify they're the same.

No, only native_blob.bin is same, snapshot-blob.bin is still different

Yes, I meant for native_blob.bin specifically.

Yes. natives_blob.bin is just a serialized form of the minified js scripts that V8 uses to implement some built-ins. Its format and content is independent of the platform.

Remove natives_blob.bin's arch dependence.

This is first patch which keeps renaming logical in gn, but didn't rename natives_blob.bin to arch specific name, so the v8 patch (https://codereview.chromium.org/2074283002/) could be landed afterwards without breaking anything.
