[PATCH] D55997: Add support for LLVM profile for NetBSD

[Kamil Rytarowski via Phabricator via llvm-commits]

krytarowski added a comment.

@joerg I was trying to change atexit(3) calls to C++ destructors or GCC destructiors (`__attribute__((destructor))`), but none of that worked.

For the former:

  /public/llvm-build/lib/clang/8.0.0/lib/netbsd/libclang_rt.profile-x86_64.a(InstrProfilingRuntime.cc.o): In function `__clang_call_terminate':
  InstrProfilingRuntime.cc:(.text.__clang_call_terminate[__clang_call_terminate]+0x2): undefined reference to `__cxa_begin_catch'
  InstrProfilingRuntime.cc:(.text.__clang_call_terminate[__clang_call_terminate]+0x7): undefined reference to `std::terminate()'
  /public/llvm-build/lib/clang/8.0.0/lib/netbsd/libclang_rt.profile-x86_64.a(InstrProfilingRuntime.cc.o):(.data.DW.ref.__gxx_personality_v0[DW.ref.__gxx_personality_v0]+0x0): undefined reference to `__gxx_personality_v0'
  clang-8: error: linker command failed with exit code 1 (use -v to see invocation)

For the latter hangs and crashes of many/all tests.
