SourceInfoTransformMacro

These internal methods are not part of the public-facing API!

The equivalent public-facing methods do not have the do_ prefix or have the same name. Use and look at the documentation for those. If you want left shift, use <<, not do_<<. If you want conversion to a Seq of Bools look at the asBools above, not the one below. Users can safely ignore every method in this group!

🐉🐉🐉 Here be dragons... 🐉🐉🐉

These do_X methods are used to enable both implicit passing of SourceInfo and chisel3.CompileOptions while also supporting chained apply methods. In effect all "normal" methods that you, as a user, will use in your designs, are converted to their "hidden", do_*, via macro transformations. Without using macros here, only one of the above wanted behaviors is allowed (implicit passing and chained applies)---the compiler interprets a chained apply as an explicit 'implicit' argument and will throw type errors.

The "normal", public-facing methods then take no SourceInfo. However, a macro transforms this public-facing method into a call to an internal, hidden do_* that takes an explicit SourceInfo by inserting an implicitly[SourceInfo] as the explicit argument.
