--- Comment #12 from Robin Dapp <rdapp at gcc dot gnu.org> ---
We're really at a point where just building becomes a burden and turnaround
times are annoyingly high.  My suspicion is that the large number of modes
combined with the number of insn patterns slows us down.  Juzhe added a lot=
 of
VLS patterns (or rather added VLS modes to existing patterns) around the
Cauldron and this is where we saw the largest relative slowdown.

Maybe we need to bite the bullet and not use the convenience helpers anymor=
e or
at least very sparingly?  I'm going to make some experiments on Wednesday to
see where that gets us.=
