请问aarch64-linux-android-clang++支持neon 指令集吗？

您好：

 请问aarch64-linux-android-clang++编译器支持neon指令集吗？现在我有个图像视差算法使用neon 指令集写的，如果aarch64-linux-android-clang++支持 neon，请问该加什么参数？

 我用同样的代码 在aarch64-linux-android-gcc下编译时通过的，aarch64-linux-android-clang++编译器不通过编译错误如下：

aarch64-linux-android-clang++   ./cost_accumulation.s ./case_cost_accumulation.c  -o case_cost_accumulation
clang50++: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated [-Wdeprecated]
/tmp/case_cost_accumulation-23c6f2.o: In function `main':
./case_cost_accumulation.c:(.text+0x334): undefined reference to `asm_cost_accumulation(unsigned long, unsigned long, unsigned short*, unsigned short*, unsigned short*, unsigned short*, unsigned short*, unsigned short*)'
clang50++: error: linker command failed with exit code 1 (use -v to see invocation)

怀疑是aarch64-linux-android-clang++不支持neon，造成汇编函数没有编译，找不到该函数
