See https://gitlab.com/rurban/gperf/-/tree/nbperf
This is mergable, but I'm working on more:

  • getting the original authors FSF assignment.


  • add more MPH hash function options (wyhash, fnv, crc intrinsics)

  These functions need to added to the generatd code.

  • keyword padding optional resp. hash-specific

  https://gitlab.com/rurban/gperf/-/issues/2
  faster hash function require uint32_t access, which violate valgrind and asan. either pad the words, but this harms very small unaligned platforms, such as avr.

The current branch also fixes minor validate (extracheck) issues with const in generated KR-C code, and adds an optional gitlab-ci pipeline.
