Subject: Fix lexical-binding fallout in vhdl-mode.el
X-Git-Tag: emacs-28.1.90~90
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=a769cbfcfb6e9603bcd15e90f387207f8c061bf1;p=emacs.git

Fix lexical-binding fallout in vhdl-mode.el

* lisp/progmodes/vhdl-mode.el (arch-alist, pack-alist)
(file-alist, unit-alist, rule-alist): Defvar them, since vhdl-aput
expects them to be dynamically bound.  (Bug#55389)
(vhdl-speedbar-insert-hierarchy): Rename the PACK-ALIST argument
to PACKAGE-ALIST, to avoid shadowing the global variable.
