Subject: back.rtlil: fix handling of certain nested arrays.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=0d61404e1ced0e7f39a5527630b32bd703f11618;p=nmigen.git

back.rtlil: fix handling of certain nested arrays.

This triggers on code like:

c1 = Signal()
c2 = Signal()
c3 = Signal()
v1 = Array([Const(1, 8), Const(2, 8)])[c1]
v2 = Array([Const(3, 8), Const(4, 8)])[c2]
v3 = Array([v1, v2])[c3]

Fixes #226.
