Autotuner broken for bfast

[Munksgaard]

I think this is caused by the new pretty-printer inserting newlines in the output of --print-sizes. The regex that looks for sizes will fail given the inserted newlines.

New:

[jxk588@gpu04:~/src/futhark]$ futhark-master opencl futhark-benchmarks/rodinia/lud/lud.fut && ./futhark-benchmarks/rodinia/lud/lud --print-sizes
[...]
main.suff_intra_par_14 (threshold([!main.suff_outer_par_13], 32))
main.suff_intra_par_20 (threshold([], 32))
main.suff_intra_par_22 (threshold([!main.suff_intra_par_20], 32))
main.suff_intra_par_6 (threshold([], 32))
main.suff_intra_par_8 (threshold([!main.suff_intra_par_6], 32))
main.suff_outer_par_13 (threshold([]))
main.suff_outer_par_15 (threshold([!main.suff_outer_par_13, !main.suff_intra_par_14]))
main.suff_outer_par_16 (threshold([!main.suff_outer_par_15, !main.suff_outer_par_13,
           !main.suff_intra_par_14]))
main.suff_outer_par_17 (threshold([!main.suff_outer_par_16, !main.suff_outer_par_15,
           !main.suff_outer_par_13, !main.suff_intra_par_14]))

Old:

[jxk588@gpu04:~/src/futhark]$ futhark-0.19.1 opencl futhark-benchmarks/rodinia/lud/lud.fut && ./futhark-benchmarks/rodinia/lud/lud --print-sizes

I think the offending commit is 70e8bda c0c5d25

[athas]

Oh yes, it's too easy to accidentally prettyprint lists. This should use spread instead.

[Munksgaard]

Ugh, it's not that simple....

main.suff_intra_par_10(threshold(, 32))

vs

main.suff_intra_par_10 (threshold ())

[athas]

You need to fix the auto-tuner. Although that printing format isn't exactly great...

[athas]

I'm working on this.
