[Bug c/37807] Exponential compile time with MMX builtins.

[suckfish at ihug dot co dot nz]

------- Comment #2 from suckfish at ihug dot co dot nz  2008-10-11 21:35 -------
Using '-da' it looks like the 'combine' pass is the culprit:

$ pidof cc1
6410
$ ls -l /proc/6410/fd
... 4 -> ... slow.c.162r.combine
$ ls -s slow.c.162r.combine
0 slow.c.162r.combine

[is there an easier way to get cc1 to tell me what pass it's running when?]
