https://bugs.gentoo.org/635674 From ca6b6f3ad9190814ef7869e8c7e73dae0922f647 Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Mon, 3 Jul 2017 15:31:10 +0200 Subject: [PATCH] libunwind-arm: fix build failure due to asm() mesa3d on ARM build with libunwind support enabled fail to build due to asm() function used when building with -std=c99. The gcc documentation [1] suggest to use __asm__ instead of asm.
