Expand description
This group of functions has more performance or precision issues than system versions, or
are otherwise less well tested. Provide them only on platforms that have problems with the
system libm
.
As libm
improves, more functions will be moved from this group to the first group.
Do not supply for any of the following:
- x86 without sse2 due to ABI issues
- https://github.com/rust-lang/rust/issues/114479
- but exclude UEFI since it is a soft-float target
- All unix targets (linux, macos, freebsd, android, etc)
- wasm with known target_os
