A cross platform C99 library to get cpu features at runtime.
[The comment about RISC-V devicetree extension order](https://github.com/google/cpu_features/blame/main/src/impl_riscv_linux.c#L25) is not aligned with the URL in the comment. This is mea culpa, because I initially got it wrong & came back and...
Hello, I also experiencing an error when trying to install.

Hello, I'm trying to build the [VOLK](https://github.com/gnuradio/volk) libraries on [Haiku](https://www.haiku-os.org/) (operating system). VOLK uses `cpu_features` as a submodule, I want/need to do a shared build but it doesn't work. To...
These headers are installed by the FreeBSD port manually: ``` Error: Missing: include/cpu_features/cpuinfo_aarch64.h Error: Missing: include/cpu_features/cpuinfo_arm.h Error: Missing: include/cpu_features/cpuinfo_mips.h Error: Missing: include/cpu_features/cpuinfo_ppc.h Error: Missing: include/cpu_features/internal/hwcaps.h ``` Should they be installed...
https://github.com/google/cpu_features/pull/291 introduced shorter INTROSPECTION_TABLE in impl_aarch64_windows.c so while public headers declare AARCH64_LAST_=78 only 54 entries were inited in kGetters kFeatureNames. Thus iterating all features upto AARCH64_LAST_ caused crash as long...
Add avx-ifma detection according to the https://en.wikipedia.org/wiki/CPUID#EAX=7,_ECX=1:_Extended_Features.
Will it be possible to add a basic support for Darwin on PowerPC? It is desirable, since `cpu_features` is a dependency used by other software, which otherwise cannot be built.
