Summary: If the output file is a character file (e.g. /dev/null) unlinking it could potentially destabilize the user's system. For example, unlinking causes `lld %input -o /dev/null` to replace /dev/null with a regular file, which will lead to unexpected behavior in other programs that read from /dev/null, and worse than expected peformance for programs that write to /dev/null. This makes it possible to run the test-release.sh script as root. Prior to this patch, the ELF/basic.s test would replace /dev/null with a regular file, which would cause crashes in llvm test-suite programs that piped /dev/null to stdin. For example, if you run the test-relase.sh script as root, Reviewers: ruiu Reviewed By: ruiu Subscribers: emaste, llvm-commits Differential Revision: https://reviews.llvm.org/D34917 llvm-svn: 307092 |
