Hello,

I tried to compile Linux kernel v2.1.86, v2.1.87 and v2.1.88 with this
options:

pgcc -D__KERNEL__ -O6 -fomit-frame-pointer -fno-exceptions
-fno-strength-reduce -I/usr/src/linux-2.1.XX -Wall -Wstrict-prototypes
-mpentium -malign-loops=2 -malign-jumps=2 -malign-functions=2 -pipe

It compiles OK, i copy it in "/vmlinuz" and type "lilo", then "reboot -t
5"
computer restarts, Linux goes up and stop on line:

Adding Swap: XXXXXk swap-space (priority -1)

and nothing happens for long time.
When i try Ctrl-C appears:

Starting kerneld, version 2.1.85 (pid XXXX)

And thats all. Only thing that helps is HW reset.
When i used -O3, -O4, -O5 but every time happens the same thing.
With -O2 all seems to be OK, just like when i compile with gcc (also OK
is -O6 with gcc). This is tested on 3 different machines(with
pgcc-2.90.23 980102 and pgcc-2.91.08 280214).
	
So i'm wonder if this is a bug in PGCC or in Linux kernel.
Any ideas.
Thanks.

Petkan
