The `feature_detect` module is currently being built on all targets, but
the use of `AtomicU32` causes a problem if atomics are not available
(such as with `bpfel-unknown-none`). Gate this module behind
`target_has_atomic = "ptr"`.
The below now completes successfully:
cargo build -p compiler_builtins --target=bpfel-unknown-none -Z build-std=core
Fixes: https://github.com/rust-lang/compiler-builtins/issues/908
libm
A Rust implementations of the C math library.
Usage
libm provides fallback implementations for Rust's float math functions in
core, and the core_float_math feature. If what is available suits your
needs, there is no need to add libm as a dependency.
If more functionality is needed, this crate can also be used directly:
[dependencies]
libm = "0.2.11"
