Subject: [PATCH 02/10] Introduce stamp file for hw-config.h
Date: Thu, 8 Apr 2021 14:33:04 -0600 [thread overview]
Message-ID: <20210408203312.2938165-3-tom@tromey.com> (raw)
In-Reply-To: <20210408203312.2938165-1-tom@tromey.com>
This adds a stamp file for hw-config.h, to avoid unnecessary rebuilds.
It also arranges to remove hw-config.h in "mostlyclean", because the
file is created by "make".
2021-04-08 Tom Tromey <tom@tromey.com>
* Make-common.in (stamp-hw): New target.
(hw-config.h): Depend on stamp-hw.
(mostlyclean): Remove stamp-hw and hw-config.h.
