Hi,
small update on status. At -O3 -fno-tree-fre -fno-tree-pre we are now doing
1.1GB footprint, 800MB of this out of gimple. We still explode in FRE/PRE but
majority of other problems was fixed:
Execution times

Also forgot to mention, integration is slow because of the split_block
quadraticness.
For -O2:
We need 531MB of ram, GGC memory is peaking at 100MB, large portion of the
non-GGC memory are definitly the scheduler
Currently, allocated memory is freed by calling the library function
_gfortran_internal_free, which does nothing but:
/* Free internally allocated memory. Pointer is NULLified. Also used to
free user allocated memory. */
void
internal_free (void *mem)
{
if (mem != NULL)
free (mem);
}

To keep things separate, I filed PR30723 for the missed optimization.

Here's another patch for concat, to have the front-end generate the code itself
instead of calling a library function. It still generates the extra temporary,
but can optimize other things.

Ahh, exploding recursive templates...
For future reference, you could limit the recursion depth explicitly, using
-ftemplate-depth-n
from a gcc-3.4.0 man page:
Set the maximum instantiation depth for template clas

>From the dictionary: obsolescent -> Going out of use; becoming obsolete;
So this means its not obsolete yet, and thus still supported.
I will fix this. Splitting hairs really, but what the heck.

If you use -fno-strict-aliasing and it works, that should tell you something
right there really.
Anyways you are violating C/C++ aliasing rules, see PR 21920.
