Hi all,

With Opal, if you want to customize how methods are compiled into a class you can override #compilerClass on class-side:
MyClass class>>#compilerClass
^ MySpecialCompiler

I�ve missed this feature. This is super cool!

There is now in addition #compiler, an instance, not the class.

This is useful as you can set compiler options this way. e.g. InstructionStream does not need to use a subclass but can do

compiler

"The JIT compiler needs to trap all reads to instance variables of contexts. As this check is costly, it is only done

in the long form of the bytecodes, which are not used often. In this hierarchy we force the compiler to always generate

long bytecodes"

^super compiler options: #(+ optionLongIvarAccessBytecodes)
