Description-en: cross platform C99 library to get cpu features
Cross-platform C library to retrieve CPU features(such as available
instructions) at runtime.
.
Design rationale:
.
* Simple to use.
* Extensible. Easy to add missing features or architectures.
* Compatible with old compilers and available on many architectures so it
can be used widely. It's implemented it in C99.
* Sandbox-compatible. The library uses a variety of strategies to cope with
sandboxed environments or when cpuid is unavailable.
* Thread safe, no memory allocation, and raises no exceptions. cpu_features
is suitable for implementing fundamental libc functions like malloc,
memcpy, and memcmp.
* Unit tested.
