From c1781787f8425d7baea3e399667dac97e8850665 Mon Sep 17 00:00:00 2001 From: Frank Hunleth <fhunleth@troodon-software.com> Date: Fri, 13 Dec 2013 09:56:11 -0500 Subject: [PATCH] erlang: add option to enable SMP support Erlang builds two emulators depending on whether SMP is supported or not. If it is known that the target does not support SMP, turning off the SMP emulator saves compile time and reduces the size of the installation.
