[^missing-stack-probes]: Stack probes support is missing on
`aarch64-unknown-linux-gnu`, but it's planned to be implemented in the near
future. The implementation is tracked on [issue #77071][77071].
[^windows-support]: Only Windows 10 currently undergoes automated testing. Earlier versions of Windows rely on testing and support from the community.
[^x86_32-floats-return-ABI]: Due to limitations of the C ABI, floating-point support on `i686` targets is non-compliant: floating-point return values are passed via an x87 register, so NaN payload bits can be lost. See [issue #114479][x86-32-float-issue].
