Disable DCHECK

[A. S.]

Hi, 

is it possible to disable DCHECK functions in debug-d8 with a flag? 

Or do I have to recompile it with manually manipulated code?

Mostly, you have compiler-time options only. With a bit of work, you could make it a runtimes option.

Compile-time:

You can disable some DCHECKs with the gn option `v8_enable_slow_dchecks = false`. If you want to turn them all off, I think you’d have to patch src/base/logging.h manually to not emit the assertions when DEBUG is defined.

Runtime:

There is an API exposed to embedders, to intercept assertion failures, but I don’t believe d8 uses it.

Hope that helps a bit.
