Therefore it makes sense to disable the runtime check by default on this platform, until either this is fixed or a clang-cl compatible intrinsic check is added (I don't have enough knowledge of MSVC to do this) +--- + cmake/OpusConfig.cmake | 7 ++++++- + 1 file changed, 6 insertions(+), 1 deletion(-) + +diff --git a/cmake/OpusConfig.cmake b/cmake/OpusConfig.cmake +index e9319fbad..d0f459e88 100644 +--- a/cmake/OpusConfig.cmake ++++ b/cmake/OpusConfig.cmake +@@ -71,7 +71,12 @@ elseif(OPUS_CPU_ARM AND NOT OPUS_DISABLE_INTRINSICS) + opus_detect_neon(COMPILER_SUPPORT_NEON) + if(COMPILER_SUPPORT_NEON) + option(OPUS_USE_NEON "Option to enable NEON" ON) +- option(OPUS_MAY_HAVE_NEON "Does runtime check for neon support" ON) ++ if (MSVC AND CMAKE_CXX_COMPILER_ID STREQUAL "Clang") ++ set(NEON_RUNTIME_CHECK_DEFAULT OFF) ++ else() ++ set(NEON_RUNTIME_CHECK_DEFAULT ON) ++ endif() ++ option(OPUS_MAY_HAVE_NEON "Does runtime check for neon support" ${NEON_RUNTIME_CHECK_DEFAULT}) + option(OPUS_PRESUME_NEON "Assume target CPU has NEON support" OFF) + if(CMAKE_SYSTEM_PROCESSOR MATCHES "aarch64") + set(OPUS_PRESUME_NEON ON) |
