// asan and msan will not call the new handler.
// UNSUPPORTED: sanitizer-new-delete
// FIXME change this to XFAIL.
// UNSUPPORTED: no-aligned-allocation && !gcc
// Aligned allocation was not provided before macosx10.12 and as a result we
// get availability errors when the deployment target is older than macosx10.13.
// However, AppleClang 10 (and older) don't trigger availability errors.
// XFAIL: !(apple-clang-9 || apple-clang-10) && availability=macosx10.12
// XFAIL: !(apple-clang-9 || apple-clang-10) && availability=macosx10.11
// XFAIL: !(apple-clang-9 || apple-clang-10) && availability=macosx10.10
// XFAIL: !(apple-clang-9 || apple-clang-10) && availability=macosx10.9
// XFAIL: !(apple-clang-9 || apple-clang-10) && availability=macosx10.8
// XFAIL: !(apple-clang-9 || apple-clang-10) && availability=macosx10.7
// On AppleClang 10 (and older), instead of getting an availability failure
// like above, we get a link error when we link against a dylib that does
// not export the aligned allocation functions.
// XFAIL: (apple-clang-9 || apple-clang-10) && with_system_cxx_lib=macosx10.12

// On Windows libc++ doesn't provide its own definitions for new/delete
// but instead depends on the ones in VCRuntime. However VCRuntime does not
// yet provide aligned new/delete definitions so this test fails to link.
