     * fptrans
       * huge, needs to be split into much smaller subtasks.
         it's enough work that, except for the tasks already split out
         (recip/[r]sqrt/mod/rem and fminmax) we should probably eliminate
         it entirely from this grant due to being lower priority and
difficult.

now you're starting to get it, ehn? it's a frickin lot of
work, to think like this, doing advance planning, isn't it?

i.e. *when* you have the estimates, you *can* start to go
"oh shite that's way too much work for the money" rather
than rush ahead and do 5 months work for 2 weeks money
(or zero because the actual 2 week task was never done).

     * FPSCR/FP regs and dependency stuff, and loads/stores.
       jacob: I have no experience working on that part of the code,
       so I'd like someone else to estimate that.

nnope.  it will be good practice for you to do some estimates
on things you *don't* know anything about, because if *you*
are the one to implement it, *you* are the one that needs
the direct feedback - to yourself - to get better at doing the
estimates, aren't you?

plus, you need to know in advance clearly what you are going
to be doing, don't you? now would be a good time to find out,
wouldn't it? (hint: i already described it to you, last week).

plus, what if you find that the estimates come out at 4 weeks,
or 8 weeks, or 4 months?

with only EUR 8,000 those different estimates represent
30%, 60% and 150% of the available budget, don't they?

which would each have a radically different impact on
the number of instructions that could be added, wouldn't it?

30, 15, and zero respectively sounds about right, yeh?
