GCC seems to define __ARCH__
, where ARCH
can be skylake
, znver4
etc.
Clang seems to define something similar such as __corei7__
and __znver4__
etc.

Looking at timings at uops.info, it seems like only Zen 2, Zen 3, Zen 4, Sandy Bridge and Ivy Bridge has fast vroundpd
.
Haswell and Broadwell has 6 in latency, but 2 in throughput. The same goes for Zen 1, but 4 in latency.
The rest of the architectures supporting AVX2 have 8 in latency and 1 in throughput.
