Throw helper methods

[ladeak]

In the past it was beneficial for high performance code to separate a throw "helper method".

e.g.

if(i < 0)
    Throw();

...

void Throw() => throw new MyException();

It was beneficial for better inlining, less code on hot paths etc.

Is this still the case? Isn't the JIT going to inline these methods nowadays?

It's more important for reducing code size now. The JIT will place throw into cold area of the method.

Isn't the JIT going to inline these methods nowadays?

JIT won't inline always-throw methods now, which is expected for optimization. It will also place the call instruction to it into cold area.
