mipp::cvt<int16_t,int32_t> failure about mipp

[kouchy]

This is weird. The implementation is here : https://github.com/aff3ct/MIPP/blob/master/src/mipp_impl_AVX512.hxx#L3631.
Are you using a mipp::Reg_2 as function parameter ?

[mtakatz]

No, it was Reg. If that's the case, maybe that's the simple answer. I'll check later today and let you know. Thanks. I love this library, btw. Mark

That was it, I appreciate the help. I didn't see another way to contact anybody. Thank you.

You're welcome :-)

Building and running on an AVX512 system (-march=native compile flag) and get the following error with the cvt function:

terminate called after throwing an instance of 'std::runtime_error' what(): mipp::cvt<int16_t,int32_t> (AVX512) is undefined! Aborted

Could you share about how you solve this? I have the same issue as you did.

terminate called after throwing an instance of 'std::runtime_error'
what(): mipp::cvt<int8_t,int16_t> (SSE3) is undefined!

[mtakatz]

For my case, using AVX512, I was using an incorrect input. I needed to use a Reg_2, not a Reg. I don't know if that will be the same for SSE3, but maybe.

mipp::Reg in;
in.load((short *) &data[data_index]);
// in.low()/high() create a type Reg_2
mipp::Reg ival_low = mipp::cvt<short,int>(in.low());
mipp::Reg ival_high = mipp::cvt<short,int>(in.high());
mipp::Reg fval_low = mipp::cvt<int,float>(ival_low) ;
mipp::Reg fval_high = mipp::cvt<int,float>(ival_high);
