In this blog post, we will explore the compiler passes that make up the compiler’s front end.
This is the first of a series of blog posts about the compiler. There
will be blog posts about how the compiler works now, how it might work
in the future, and some historical notes to explain why some things
are what they are. In this blog post I will talk about one of the most
useful options for exploring the compiler, namely the
Erlang/OTP 21 will introduce a completely new IO polling implementation. This new implementation comes with a new set of tuneable parameters that can be used to get the most out of your system. This blog post describes the parameters and attempts to describe what they should be used for.
