def Lean.Compiler.LCNF.shouldGenerateCode (declName : Name) : CoreM Bool

We do not generate code for declName if

• Its type is a proposition.
• Its type is a type former.
• It is tagged as [macro_inline].
• It is a type class instance.

Remark: we still generate code for declarations tagged as [inline] and [specialize] since they can be partially applied.

def Lean.Compiler.LCNF.checkpoint (stepName : Name) (decls : Array Decl) : CompilerM Unit

A checkpoint in code generation to print all declarations in between compiler passes in order to ease debugging. The trace can be viewed with set_option trace.Compiler.step true.
