we're continuing to increase, thus re-confirmed.

Blocks the memory-hog meta-bug which is marked as regression.

richi, can you share this maxmem2 script?

--- Comment #19 from Steven Bosscher <steven at gcc dot gnu.org> 2012-08-28 09:34:10 UTC ---
With r190665, compile time is mostly spent in:
 loop doloop             : 130.15 ( 8%) usr
 variable tracking       : 990.72 (60%) usr
 var-tracking dataflow   :  76.34 ( 5%) usr

So this isn't a DF issue in GCC 4.8 at least, but yet another var-tracking
issue (but probably not related to bug 53958, because var-tracking dataflow
time is almost reasonable here).

I'll have a look at the doloop issue, but the var-tracking issue is for Alex.

With release checking, the loop-doloop time is almost zero (so something is
slow in doloop checking). The var-tracking slowness does not disappear, and
dominates the compile time even more strongly:

 variable tracking       : 530.57 (84%) usr
