[Message part 1 (text/plain, inline)]

When visiting any VHDL file, trying to execute vhdl-generate-makefile
(C-c M-k) will fail if vhdl-project is nil. The resulting error message
and backtrace are as follows:

vhdl-generate-makefile-1: Symbol’s value as variable is void: rule-alist

Debugger entered--Lisp error: (void-variable rule-alist)
  vhdl-aput(rule-alist "counter.vhd" (("counter") nil))
  vhdl-generate-makefile-1()
  vhdl-generate-makefile()
  funcall-interactively(vhdl-generate-makefile)
  command-execute(vhdl-generate-makefile)

I suspect this might be due to changes when lexical-binding was enabled,
I went back to commit d365c947b53a2a1e4b43ab65922ebfeca23943d1 where it's
working. Note that I've never used this feature before so I don't know
exactly how it's supposed to behave, I wanted to try it out. The
makefile I get from the older vhdl-mode.el does seem to make sense though, I’ve
attached it for reference.
