Vl-genarray

A loop generate construct, after elaboration.

This is a product type, introduced by deftagsum in support of vl-genelement.

Fields
name — maybe-string
Name of the block array, if named.
var — stringp
Iterator variable name.
genvarp — booleanp
Was the variable declared using the genvar keyword, locally
blocks — vl-genblocklist
Blocks produced by the loop
loc — vl-location
Where the loop came from in the Verilog source code.

This is a post-elaboration representation of a generate for loop, where the loop itself is gone and we instead have something like a list of begin/end blocks for each value that var took on during the loop's execution.

This representation may seem weird but notice that things like the sizes of wires can change from iteration to iteration if they depend on the loop variable, and similarly other things within the loop like if/else generate blocks may depend on the loop variable and so may need to differ from iteration to iteration. To support these kinds of things, we really do want a representation where each block can be separated from the others and processed independently.
