Avoid empty .eh_frame sections. Strip on OpenBSD does not correctly handle an empty .eh_frame section and produces broken binaries in that case. Currently lld creates such an empty .eh_frame section, despite the fact that the OpenBSD crtend.o explicitly inserts a terminator. The Linux LSB "standard": https://refspecs.linuxfoundation.org/LSB_5.0.0/LSB-Core-generic/LSB-Core-generic/ehframechpt.html#EHFRAME explicitly says that The .eh_frame section shall contain 1 or more Call Frame Information (CFI) records. This diff includes a test that specifically tests the issue I'm seeing on OpenBSD. Patch by Mark Kettenis! llvm-svn: 301931

[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651
