-//! Android ABI-compatibility module
-//!
-//! The ABI of Android has changed quite a bit over time, and std attempts to be
-//! both forwards and backwards compatible as much as possible. We want to
-//! always work with the most recent version of Android, but we also want to
-//! work with older versions of Android for whenever projects need to.
-//!
-//! Our current minimum supported Android version is `android-9`, e.g., Android
-//! with API level 9. We then in theory want to work on that and all future
-//! versions of Android!
-//!
-//! Some of the detection here is done at runtime via `dlopen` and
-//! introspection. Other times no detection is performed at all and we just
-//! provide a fallback implementation as some versions of Android we support
-//! don't have the function.
-//!
-//! You'll find more details below about why each compatibility shim is needed.

-// The `log2` and `log2f` functions apparently appeared in android-18, or at
-// least you can see they're not present in the android-17 header [1] and they
-// are present in android-18 [2].

-// Note that these shims are likely less precise than directly calling `log2`,
-// but hopefully that should be enough for now...
-//
-// Note that mathematically, for any arbitrary `y`:
-//
-//      log_2(x) = log_y(x) / log_y(2)
-//               = log_y(x) / (1 / log_2(y))
-//               = log_y(x) * log_2(y)
-//
-// Hence because `ln` (log_e) is available on all Android we just choose `y = e`
-// and get:
-//
-//      log_2(x) = ln(x) * log_2(e)

-// Back in the day [1] the `signal` function was just an inline wrapper

-// symbols was introduced [2]. Finally, in android-21 the API `bsd_signal` was
-// removed [3].
-//
-// Basically this means that if we want to be binary compatible with multiple
-// Android releases (oldest being 9 and newest being 21) then we need to check
-// for both symbols and not actually link against either.
