vhdl-compile-use-local-error-regexp

vhdl-compile-use-local-error-regexp is a variable defined in `vhdl-mode.el'.
Its value is

nil

Documentation:
Non-nil means use buffer-local `compilation-error-regexp-alist'.
In this case, only error message regexps for VHDL compilers are active if
compilation is started from a VHDL buffer. Otherwise, the error message
regexps are appended to the predefined global regexps, and all regexps are
active all the time. Note that by doing that, the predefined global regexps
might result in erroneous parsing of error messages for some VHDL compilers.

NOTE: Activate the new setting by restarting Emacs.

You can customize this variable.

This variable was introduced, or its default value was changed, in version 25.1 of Emacs.
