There were two bugs spotted here:

  • (1 << feature_addr) was only a 32 bit value because neither 1 nor feature_addr were 64 bits, so 64 bit features would be generated wrongly
  • bits is not shifted by start_bit, so the test of it should start from 0 rather than start_bit

With this I can get the himbaechel-xilinx blinky example to correctly build for arty-a35t using this for assembly.
