  12 // as a system library on Apple platforms.

  14 // Make sure we install the libc++abi headers in the right location.
  15 // TODO: We don't currently install them, but we should.

  20 //
  21 // RUN: stat "%{lib}/libc++abi.dylib"
  22
  23 // Make sure we don't install a symlink from libc++abi.dylib to libc++abi.1.dylib,
  24 // unlike what we do for libc++.dylib.
  25 // TODO: We currently don't do that correctly in the CMake build.

  30 // Make sure the install_name is /usr/lib.
  31 //
  32 // In particular, make sure we don't use any @rpath in the load commands. When building as
  33 // a system library, it is important to hardcode the installation paths in the dylib, because
  34 // various tools like dyld and ld64 will treat us specially if they recognize us as being a
  35 // system library.

  37 // TODO: We currently don't do that correctly in the CMake build.

  42 // Make sure the compatibility_version of libc++abi is 1.0.0. Failure to respect this can result
  43 // in applications not being able to find libc++abi when they are loaded by dyld, if the
  44 // compatibility version was bumped.
