------- Comment #49 from rguenth at gcc dot gnu dot org 2005-10-07 11:17 -------
So trying to get some updated comparison I noticed that the testcase fails to
compile with 3.3.x and compared to 3.4.x we have improved a lot wrt -O2
compile-time:
3.4: 1m32s, peak at 230MB
4.1: 48s, peak at 480MB
Still we are using too much memory. Time-report for 4.1 does no longer show
obvious problems:

You might consider opening a 4.2 PR since there are definitely
things that could be further improved from a compile-time standpoint
for the code referenced in this PR.

Mark, there's probably not much else we can do in this PR for 4.1. What I see
in the aliasing times involves quite a few changes, most of them from the
aliasing branch and some other similarly intrusive changes I've got on the
side.
Other than that, the timings are now relatively reasonable. How do you want to
handle this?

The original report was about crashing. Now we don't. So, clearly,
this PR should be closed.
If you think that we should still be able to do better in terms of
compile-time performance or memory usage, please open a new PR, targeted
at 4.2.
Thanks,

Compiling the attached C++ code caused the following error with g++ 3.4.0 when compiled with -O2
or -O3. -O1 and no optimization works fine. No warnings other than unused variables and parameters
are generated by -Wall. (Extensive editing was done to make the source code 'compatible' with gcc
3.4.0 (so much stricter than 3.3.x).
g++ was built on this machine with ld and as from binutils 2.14.

at -O1 on the mainline on powerpc-darwin, we now take over 800M which seems very high. I could not
finish the build of this source as it was just taking too long.

On ia64-linux postreload-gcse does exactly nothing and takes 35% of the compile
time at -O1 -fgcse-after-reload. I didn't finish a build at -O2.

What testcase and compiler version are you using for this? I tried
taking a look, but wasn't able to reproduce any problem. I was able to
compile both testcases in the PR at -O2 in about 20 secs and about 200MB.
Both testcases in the PR have issues. The first one generates lots of
errors from the C++ front end, and doesn't actually end up doing much
compiling. The second one wants a non-existent expat.h file and is thus
uncompilable without changes. If I delete the include of the missing
expat.h file, then again I get C++ front end errors and little compilation.
I tried various gcc versions, 4.0.x, mainline, 3.3.x, but I got the same
result from all of them.
Maybe you have a copy of the missing expat.h file?

The second testcase works for me on current mainline if adding a class UltraRoot
forward declaration at the top. It takes around 1m30 to compile and uses up
max. 522913kB of memory (1GB box, P4 2.8GHz) at -O2. Still aliasing accounts for
the most time:
samples % image name symbol name
694 26.6411 cc1plus add_stmt_operand
209 8.0230 cc1plus ldst_entry
193 7.4088 cc1plus create_ssa_artficial_load_stmt
181 6.9482 cc1plus compute_global_livein
57 2.1881 cc1plus bitmap_bit_p
50 1.9194 no-vmlinux (no symbols)
45 1.7274 cc1plus compute_may_aliases
42 1.6123 cc1plus invalidate
36 1.3820 cc1plus bitmap_ior_and_compl_into
35 1.3436 cc1plus bitmap_set_bit
35 1.3436 cc1plus for_each_rtx_1
33 1.2668 cc1plus check_dependence
29 1.1132 cc1plus splay_tree_splay_helper
28 1.0749 cc1plus htab_find_slot_with_hash
The 2nd is from GCSE, 3rd from DOM, 4th from either into-ssa or ssa-loop-manip.
Time-report:
tree SSA incremental : 14.27 (17%) usr 0.11 ( 3%) sys 14.46 (16%) wall
12827 kB ( 2%) ggc
tree operand scan : 15.62 (18%) usr 0.27 ( 8%) sys 15.93 (18%) wall

PRE : 6.14 ( 7%) usr 0.01 ( 0%) sys 6.13 ( 7%) wall
536 kB ( 0%) ggc
ldst_entry is walking a list to find an element by hash-id. Throw some
memory at it to add a real hashtable for lookup besides the list.
The DOM stuff looks like value numbering still in DOM, hopefully it will be
ripped out.

Now we have again (?? appeared not too long ago) DOM taking all time and memory
threading 10000 times repeating
if (__priority == 65535)
{
if (__initialize_p == 0)
{
__comp_dtor (&__ioinit);
}
else
{
}
}
else
{
}
in __static_initialization
Ugh.
