From b8e535ae8afb3d22b6326080b22c075fa5f40cd4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Wed, 8 Nov 2017 00:20:52 -0300 Subject: Makefile: simpler/faster "make help" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Using obscure black magic introduced in eaa2ddbb767 :) In an out-of-tree directory, running "../configure && make help" will generate some required files (.mak), then clone some submodules, compile at least the capstone submodule, generate QMP and Trace files, and finally display the help. On an outdated computer (Sun Blade workstation), running "make help" took more than 5h :) With this patch it took roughly 37min. Suggested-by: Daniel P.
