armclang compile arm_neon.h, there is error: unknown type name '__simd64_int8_t'

Chien-Ming Lu

I use ARM Development Studio and use it's ARM C compiler for Embedded 6. 

When I include "arm_neon.h" and using

armclang.exe --target=arm-arm-none-eabi -mcpu=cortex-a7 -mfpu=neon-vfpv4 -mfloat-abi=hard -marm -fvectorize -O0 -g -MD -MP -c -o "src/sfp_interest_point.o" "../src/sfp_interest_point.c"

../src\arm_neon.h:57:9: error: unknown type name '__simd64_int8_t'

../src\arm_neon.h:58:9: error: unknown type name '__simd64_int16_t'

../src\arm_neon.h:59:9: error: .........

According to some information, I have set the mfpu=neon-vfpv4, -mfloat-abi=hard, but the error still there.

Could some people know why I will have error?

 

Regards

Gilbert
