> [CXX] bridges/source/cpp_uno/gcc3_linux_aarch64/callvirtualfunction.cxx
> clang-12: error: argument unused during compilation:
'-fno-stack-clash-protection' [-Werror,-Wunused-command-line-argument]
as seen e.g. on macOS 11.1 ARM64 when building against Clang 12 trunk.
Clang
supports -fstack-clash-protection on
> $ clang --target=x86_64-unknown-linux-gnu -fstack-clash-protection
-fsyntax-only -x c - </dev/null
but not on e.g.
> $ clang --target=aarch64-unknown-linux-gnu -fstack-clash-protection
-fsyntax-only -x c - </dev/null
> clang-12: warning: argument unused during compilation:
'-fstack-clash-protection' [-Wunused-command-line-argument]
or
> $ clang --target=arm64-apple-macosx11.0.0 -fstack-clash-protection
