(2) I noted the following in the gcc 2.6.1 announcement:
Noteworthy changes in GCC version 2.6.1:
...
The following new configurations are supported:
GNU on x86 (instead of treating it like MACH)
NetBSD on SPARC and Motorola 68k
...
Anyone tried building 2.6.1 on a NetBSD/SPARC system yet? I wonder what new
it should work. i did the port of 2.6.0 to netbsd/sparc a few
months back, but i've since deleted it -- it didn't seem to
make much difference, though it was clearly capable of building
workable kernels ;-)
gcc 2.6.2 is out now apparently. maybe i'll d/l it tonight and
give it a go. but this static/dynamic problem isn't going to
be related to the compiler -- the linker(s) are at fault? here..
as chris noted, it's affected by cache somehow -- i had been
getting ~31k for that dhrystone, then suddently i was getting
~42k .. turns out that charles was running gdb at sometimes
and not at others ..
i don't see any difference when i put some code above or below
the loop, or anywhere else, either.
