Author: ed Date: Wed Feb 17 12:56:20 2016 New Revision: 261135 URL: http://llvm.org/viewvc/llvm-project?rev=261135&view=rev Log: 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.
