From 914bd57db76941f4ca7c33eb8e217f06f790a6c2 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Wed, 22 Nov 2017 23:25:40 +0100 Subject: [PATCH] boost: do not allow selecting fiber module on mips32/mips64 The fiber module uses the cpu_relax() macro, for which the MIPS implementation uses the "pause" instruction, only available since mips32r2 and mips64r2. In order to avoid build failures on mips32/mips64, we disallow the selection of the fiber module for such architecture variants. This solution was suggested by Arnout Vandecappelle.
