From dabe08aac070e30820506f5f6592196eedb74bbc Mon Sep 17 00:00:00 2001 From: Ed Schouten Date: Wed, 17 Feb 2016 18:56:20 +0000 Subject: [PATCH] Enable SafeStack for CloudABI. Summary: I've got a patchset in my home directory to integrate support for SafeStack into CloudABI's C library. All of the CloudABI unit tests still seem to pass. Pretty sweet! This change adds the necessary changes to Clang to make -fsanitize=safe-stack work on CloudABI. Without it, passing this command line flag throws an error.
