Try -fno-move-loop-invariants. This is probably a killer on alias-improvements
branch as well.

As this seems to be autogenerated from
! The SPL Program: (compose (sparse (coords (...12288 x 2 ...))(values (...1 x
12288 ...)))(compose (conjugate (..)(..))(compose (..)(..))))
! node size: 12288 X 12288
can you produce a testcase with an order of magnitude less loads/stores?
(thus likely just "node size: 1228 x 1228")?
Thanks!

One problem seems to be that we blow up the stack during GC recursing following
the VUSE -> def_stmt links.

I've uploaded a smaller file: gap_bzAJWH.c.gz . These are intermediated files
which are deleted upon successful compilation.
So, I've decreased the number the points and managed to "catch" this one. It
is: "node size: 1536 X 1536".

I am not sure whether it's clear - the smaller 'gap_bzAJWH.c.gz' file can be
found as

------- Comment #12 from rguenth at gcc dot gnu dot org 2009-03-01 11:39 -------
The small testcase at -O2 is bound by PRE time
PRE : 27.08 (55%) usr 0.02 ( 4%) sys 27.09 (55%) wall
1551 kB ( 2%) ggc
nothing interesting at -O1 and it still nicely fits into my memory. Which
makes me as for a little bigger testcase ;) (as I suspect there's quadratic
behavior in memory usage somewhere a size around 2000 * 2000 would be nice)
Thanks again.

And for trunk we have
combiner : 24.76 (15%) usr 0.80 (23%) sys 25.76 (16%) wall
448053 kB (82%) ggc
integrated RA : 68.41 (43%) usr 1.06 (31%) sys 70.23 (42%) wall
3197 kB ( 1%) ggc
as the worst offenders at -O1. I notice that with --enable-checking GC
params the top memory usage is way lower than without, so something odd
happens here as well (maybe a ggc_free wrapped inside ENABLE_CHECKING?).
Most memory is used by combine and IRA.

------- Comment #14 from sergstesh at yahoo dot com 2009-03-03 13:36 -------
'spiral' has produced another testcase which segfaults with -O2 - the original
testcase segfaults with -O1.
The testcase, though has half the points if terms of FFT, is big as a file:
-rw-r--r-- 1 sergei users 1656419 2009-03-03 06:36 gap_CPEodL.c.bz2
, so I think I can't upload it directly, or can I ?
I can send it as Email attachment to, say, rguenth.

Vlad, for the second testcase I see
-O0:
expand : 0.78 (19%) usr 0.04 ( 5%) sys 0.83 (16%) wall
44335 kB (49%) ggc
integrated RA : 1.05 (25%) usr 0.03 ( 4%) sys 1.13 (22%) wall
1036 kB ( 1%) ggc

-O1:
integrated RA : 73.95 (77%) usr 1.18 (50%) sys 76.20 (76%) wall

(on alias improvements branch I see
combiner : 24.89 (17%) usr 0.51 (28%) sys 25.41 (17%) wall

integrated RA : 69.81 (47%) usr 0.36 (20%) sys 70.22 (46%) wall
3212 kB ( 1%) ggc
as tree loop invariant motion does lots of stuff there)
