Trevor Gross ec1ca51298 Vendor cfg_if::cfg_if! ... `cfg_if` is helpful for applying `cfg` attributes to groups of items, like we will need to do with architecture-specific modules of `f16` and `f128`. However, `libm` can't have dependencies. The `cfg_if` macro is complex but small, so just vendor it here.		2024-10-28 22:12:13 -05:00
