This package also can be used as workaround for core.cpuid Issue 16028.

BetterC mode works when compiled with LDC only.

dub build --compiler=ldmd2 --build-mode=singleFile --parallel

• API was split to unified, target specified, and vendor specified parts.
• Complex cache topology (number of cores per cache) is supported. This feature is required by ARM CPUs.
• Translation lookaside buffers are supported. They are used in server and math software, for example cache optimized BLAS requires TLB information.
• Caches and TLBs are split into three types:
  • Data
  • Instruction (code)
  • Unified (data and code)
• _cpuid function is available for x86/x86-64 targets.

• The library was written completely from scratch.
• Code is clean and simple.
• Unions and mir.bitmanip.bitfields are used instead of bit operations.
• Slim betterC library with extern(C) insterface.

• Add information about recent features like AVX2, AVX512F.
• Add information about ARM target and ARM vendors.
• Test a lot of different CPUs.
• Extend testing infrastructure.
• CPU(package) count identification.
• Per CPU(package) CPUID information.
