Re: [macppc] BSS PLT format and ports-clang
Thanks for mentioning -msecure-plt. I grep'd our current LLVM source, and the option isn't here. But it has been added since then [1], so i'll try adding patches that enables it. Charlène.

Re: [macppc] BSS PLT format and ports-clang
What happens if you build with -msecure-plt or -fno-plt?

[macppc] BSS PLT format and ports-clang
Hi, bcallah@ (mostly) and i (who owns the hardware and builds) are currently trying to get llvm/clang working on macpcc. That would allow us to try unbreaking many ports on this platform, especially those that depend on webkitgtk4. It currently builds [1] and installs [2] properly. I then tried to build a port with clang, successfully, but it fails at runtime. This is what i get, even with a simple "hello world", on OpenBSD 6.4-current (GENERIC) #263 (2018/11/09): $ ./hello ld.so: hello: unsupported insecure BSS PLT object Recently, support for BSS PLT format has been deleted [3]. Is it possible to fix clang so we get binaries that work at runtime? Reintroducing BSS PLT is probably not the best solution, and is only considered a "decent guess" to fix the issue. Your opinions are welcome! Charlène.
