------- Comment #21 from bonzini at gnu dot org  2006-03-30 14:04 -------
Patch bootstrapped, regtesting in progress.  With checking enabled I have this
which is not bad at all.

 tree PHI insertion    :  49.68 ( 5%)
 tree SSA rewrite      :  63.75 ( 7%)
 tree SSA incremental  :   4.75 ( 1%)
 dominator optimization:  12.66 ( 1%)
 tree loop init        :   6.25 ( 1%)
 tree SSA uncprop      :   7.68 ( 1%)
 tree SSA verifier     : 214.56 (24%)
 tree STMT verifier    : 197.87 (22%)
 expand                :  21.19 ( 2%)
 loop analysis         :  10.96 ( 1%)
 global alloc          : 276.20 (30%) <-- i think this is due to
ENABLE_CHECKING

We still consume more than a GB of memory though.
