Hi, This patch adds -fversion=Linux_Pre_2639 to the druntime testsuite compile flags if the linux OS version is older than 2.6.39. The second part is from upstream druntime e03164b5, fixing PR d/89432.
Bootstrapped and regression tested on x86_64-linux-gnu. Committed to trunk as r270554. -- Iain --- libphobos/ChangeLog: 2019-04-24 Iain Buclaw <ibuc...@gdcproject.org> PR d/89432 * testsuite/lib/libphobos.exp (check_effective_target_linux_pre_2639): New proc. * testsuite/libphobos.druntime/druntime.exp: Add compiler flag -fversion=Linux_Pre_2639 if target is linux_pre_2639. * testsuite/libphobos.druntime_shared/druntime_shared.exp: Likewise. ---
