--- Comment #1 from Bernd Edlinger <bernd.edlinger at hotmail dot de> ---
current snapshot gcc-4.9-20140330, trunk revision 208948
uses 773 MB peak memory.
last week's snapshot gcc-4.9-20140323, trunk revision 208775
used only 417 MB peak memory, which did not cause problems.

started with r208910 of gcc/config/arm/cortex-a53.md
as it looks like, this single check-in did almost double the memory usage!

Kyrill,
sorry, to bother you with this,
but do you see any possibility to
return to the previous memory footprint?
Thanks
Bernd.

I'll have a look.

The problem is exacerbated by my patch, but the root cause for the state-space
explosion seems to be the extremely large reservation duration for the floating
point div reservations.
I'll see if we can reduce them without any negative impact on codegen quality.
