Disable snapshot with d8

[Rix]

I want to debug some of the Genesis builtin functions in bootstrapper.cc

However even with v8_use_external_startup_data=false set, a pre-built snapshot is still being used and there's no way to debug pre-built builtins.

Is there a compile/runtime flag I can use to disable the snapshot completely and always build the context from scratch?

I hope the following two links will help you:

You cannot disable the snapshot, but you can run the mksnapshot binary (which runs as part of the build process) in a debugger.
