3 years agoChange the type of current_module to Module
Rupert Swarbrick [Mon, 20 Apr 2020 13:41:55 +0000 (14:41 +0100)]
Change the type of current_module to Module

The current_module global is needed so that genRTLIL has somewhere to
put cells and wires that it generates as it makes sense of expressions
that it sees. However, that doesn't actually need to be an AstModule:
the Module base class is enough.

This patch should cause no functional change, but the point is that
it's now possible to call genRTLIL with a module that isn't an
AstModule as "current_module". This will be needed for 'bind' support.

Use range-based for loop in AST::process

No functional change: just get rid of the explicit iterator and
replace (*it)-> with child->. It's even the same number of characters,
but is hopefully a little easier to read.
