How to compile SVE with ArmPL?

Z_Hu over 3 years ago

Hi all,

I am using ArmPL 22 and want to use some functions in libamath, like exp, log, cos etc. By dumping libamath.so I can find intrinsics like armpl_svexp_f32_x, but it does not compile and I can not find any documents or examples. Could someone help me to compile SVE codes with ArmPL?

Thanks

Right, math.h don't seem to expose the SVE symbols. You will have to declare the one you want to use manually in the header of your file, like that:

svfloat32_t _ZGVsMxv_expf(svfloat32_t, svbool_t);

svfloat32_t _ZGVsNxv_expf(svfloat32_t);
