   3         * 532: Implemented a skeleton for compression ratio estimation,
   4         initially with the simpler mode switching of the 8-bit nop,
   5         odd-address 16-bit insns.  Next, rewrite it for all the complexity
   6         of mode switching envisioned for the "attempt 1" proposal.  (2:02)

  10         * 238: Debating various possibilities of 16-bit encoding.  (5:20)
  11
  12         * 532: Wrote a histogram python script, that breaks counts down
  13         per opcode, and within them, by operands.  (2:05)

  17         * 529: Brought up the possibilities of using 8-bit nops to switch
  18         between modes, so that 16-bit insns would be at odd addresses, so
  19         that we could use the full 16-bits; of using 2-operand insns
  20         instead of 3- for 16-bit mode so as to increase the coverage of
  21         the compact encoding.
  22         * 238: Luke moved the comment above here, where it belonged.
  23         * 529: Elaborated how using actual odd-addresses for 16-bit insns
  24         would be dealt with WRT endianness.  Prompted by luke, added it to
  25         the wiki.
  26         * Wiki: Added self to team.  (11:50)

  30         * 532: Wrote patch for binutils to print insn histogram.
  31         * Mission: Restated the proposal of adding "and users" to the
  32         mission statement, next to customers, as those we wish to enable
  33         to trust our products.  (6:48)

  38         * 238: Started looking into it, from
