XxHash Versions Save

build : new : make install target build : improved cmake script by @ChrisKitching build : fix compilation with directive XXH_ACCEPT_NULL_INPUT_POINTER enabled cli : -b : more comparable bench results at small keys

Fix : namespace emulation contains all symbols strict c90 mode, for platform without long long support removed seed from state, replaced by reserved (#79)

API : new : XXH*_copyState() API : modified : get xxHash symbols out of public space (static) using macro XXH_PRIVATE_API

Update API for static allocation (now requires macro XXH_STATIC_LINKING_ONLY)

Added : command -c / --check to xxhsum, thanks to @t-mat Updated : man page, by @t-mat

• Semantic versioning
  • availability of XXH_versionNumber() and XXH_VERSION_NUMBER for user-side test
• New canonical API, suggested by @t-mat
• New : Private API mode
• New : command line option --little-endian to display hashes with said convention
• Updated cmake install, thanks to @romange
• Breaking API change for streaming version using static allocation :
  • XXHnn_state_t is now incomplete type, and cannot be allocated directly on stack
    • required for better conformance with strict-aliasing rules
  • use XXHnn_CREATESTATE_STATIC() instead (see xxhash.h for details)

• New memory routines for efficient access on ARMv6/ARMv7 (see details )
• cmake directory

• Greatly improved performance on ARMv6
• xxhsum is compatible with list of files and wildcard symbol

Namespace emulation in C, using XXH_NAMESPACE define Better conformance with strict compilation rules

Fixed : minor alignment ajustments
