How to solve can't convert vector values between diferrent type #2

Open doublekang2018 opened 10 months ago

I'm trying to use your header file to run a SSE SIMD code on MIIPS CPU(Loongson 3A3000),it turns out with some errors. error： can’t convert between vector values of different size return vreinterpret_m128(__builtin_msa_fadd_w(vreinterpret_v4f32(a), vreinterpret_v4f32(b)));

error：can’t convert between vector values of different size extension(({union {int32_t i; typeof(x) v;} $ = {.v = x}; $.i;}))

I don't know how to solve these problems, can you help me? thank you so much.

@doublekang2018 This header file converts intel SSE intrinsic to MIPS MSA implementation. It requires your compiler to support MIPS MSA builtin functions (gcc 7.1+), and a cpu that supports MIPS MSA ASE, such as loongson 3A4000 or Ingenic x2000. As I know, the loongson 3A3000 dose not support MIPS MSA, if you just want to run SSE code on the loongson 3A3000 platform, you can try the SIMDe project.

Yes,it works perfectly on loongson 3A4000 cpu,thank you so much ! It helps me to convert my sse code to mips without any change.
