The code below is in apache arrow cpp[1]. The arrow-rs also has similiar phenomenon[2].
To be short, when size is gurantee to be less or equal to `12`, gcc would inline the `memcpy` and `memset`

We have a couple common generations of CPU above the baseline x86_64 instruction - namely sandybridge and haswell, with AVX and AVX2/BMI/BMI2 respectively.
LLVM-backed languages and GGC 4.9+ all su…

**Goal state**
`apsi` is installed as is via `vcpkg` and can be used with AVX2 on supported platforms.
**Current state**
`apsi` built from source after AVX2 support is [patched out](https://g…

Experiment: https://godbolt.org/z/H7jymg
clang and gcc do not compile `_bzhi_u32` without `-mbmi2`. So, on these compilers, setting `SNAPPY_REQUIRE_AVX2=0` should result in `HAVE_BMI2` being set to…
