--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Iain Buclaw <ibuc...@gcc.gnu.org>: https://gcc.gnu.org/g:285d81be9725acc36dc8eca48d4df506cd5e6f6f commit r11-3047-g285d81be9725acc36dc8eca48d4df506cd5e6f6f Author: Iain Buclaw <ibuc...@gdcproject.org> Date: Mon Sep 7 15:43:04 2020 +0200 libphobos: libdruntime doesn't support shadow stack (PR95680) Rather than implementing support within D runtime itself, use libc getcontext/swapcontext functions if CET is enabled. Removes whatever CET support was in the switchContext routine for x86 D runtime, along with setting version AsmExternal, so that the fallback ucontext_t implementation is used, which is capable of doing shadow stack handling. libphobos/ChangeLog: PR d/95680 * Makefile.in: Regenerate. * configure: Regenerate. * configure.ac (DCFG_ENABLE_CET): Substitute. * libdruntime/Makefile.in: Regenerate. * libdruntime/config/x86/switchcontext.S: Remove CET support code. * libdruntime/core/thread.d: Import gcc.config. Don't set version AsmExternal when GNU_Enable_CET is true. * libdruntime/gcc/config.d.in (GNU_Enable_CET): Define. * src/Makefile.in: Regenerate. * testsuite/Makefile.in: Regenerate.
