--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Note smaller #s decrease the memory usage and compiles faster but still uses a
lot of memory.

Going from 0x1000000 to 0x2000000:
 expand                             :   0.60 (100%)   0.06 (100%)   0.70 ( 97%)
  271M ( 99%)

 expand                             :   1.99 ( 98%)   0.22 (100%)   2.20 ( 96%)
  543M (100%)

As you can see double the memory usage.
