From 9ad496b2c8b9c2c41dc03cbc3e7529fc02a310ef Mon Sep 17 00:00:00 2001 From: Petr Hosek Date: Sun, 16 Apr 2017 06:08:44 +0000 Subject: [PATCH] [CMake][libunwind] Fix the -target and -gcc-toolchain flag handling CMake has the problem with the single dash variant because of the space, so use the double dash with equal sign version. The compile flag handling had a typo which caused these flag not to be properly include. We also don't have to pass the target triple when checking for compiler-rt since that flag is already included in compile flags now.
