--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
On my slowest machine (G5 1.8Ghz) I get
49.043u 2.525s 0:56.29 91.5% 0+0k 41+25io 2817pf+0w
Is it really worth the work? Could you provide a suitable splitting if yes, or
close the PR as WONTFIX if no?

This has become more pronounced with increased gfortran testing
parallelism. I'll provide more feedback next week.

Maybe post a -ftime-report, I think it might be a compile time hog ? Here, it
takes about 4s at -O3, the largest single pass is:
alias stmt walking : 1.89 (42%) usr 0.01 (11%) sys 1.95 (42%) wall
46 kB ( 0%) ggc
The testcase is really not a large program, a handwritten 300 lines of code,
working on small arrays.

I've tested on two systems with -O3 -fomit-frame-pointer:
* 1.2 GHz UltraSPARC-T2:
real 1:34.16
user 1:33.32
sys 0.43
phase opt and generate : 93.17 (99%) usr 0.40 (95%) sys 93.58 (99%) wall
31673 kB (93%) ggc
alias stmt walking : 30.76 (33%) usr 0.03 ( 7%) sys 30.84 (33%) wall
25 kB ( 0%) ggc
* 1.35 GHz UltraSPARC-IV:
real 49.37
user 44.41
sys 0.47
phase opt and generate : 44.40 (99%) usr 0.33 (97%) sys 47.62 (99%) wall
31673 kB (93%) ggc
alias stmt walking : 12.93 (29%) usr 0.02 ( 6%) sys 13.05 (27%) wall
25 kB ( 0%) ggc

Rainer,
Unless you provide a splitting that works on your slow machines, I don't see
the point to keep this PR open.
