Are there any real workloads which use functions in amdlibm_vec.h?

I find there are many vector functions such as amd_vrda_cos, amd_vrda_cosf, amd_vrda_sin ...., in AMD math library. Are there any real workloads which use those functions? I tried to find a workload which can take advantage of these functions.

Moreover, I tried writing an test example which called amd_vrda_sin, and I compiled it and ran it on an intel i9 desktop on which the OS is Ubuntu 19.10, but it always crashed with segmentation fault. I also attached the test code. Unpack it and run "make clean && make" to compile it.

Re: Are there any real workloads which use functions in amdlibm_vec.h?

Thank you for your query. For any issues or queries regarding the AMD Optimizing CPU Libraries (e.g. AMD LibM), please contact toolchainsupport@amd.com.

Anyway,  AMD Server Gurus  community seems to be better place to post this query, hence I'm moving it there.

Thanks.
