clang -v reveals that Apple LLVM 7.0.0 is based on LLVM 3.7.0svn. > So I think -fstack-protector is what I need to use, but I can't find any > Clang documentation about it. Any suggestions? Experimenting with clang -v and the various -stack-protector options reveals that Clang as far back LLVM3.1 has used -fstack-protector by default, and has -fstack-protector-all. Clang from LLVM 3.7 implements -fstack-protector-strong, which seems like the sensible thing to try as an upgrade from the basic -fstack-protector. -- John Dallman ----------------- Siemens Industry Software Limited is a limited company registered in England and Wales.
