[comp.sys.hp] interaction between chatr and cachectl in HP-UX 7.05

I have a few questions about cachectl in HP-UX 7.05:

1) If the executable has been changed to have the cache operate in
write-through mode for the data (and stack) segment, is cachectl
(I_PURGE, 0, 0) then a NOP since there are no longer any dirty D-cache
lines, or does it still flush the I cache?  If it does not, how can I
make it do that?

2) Is cachectl available for the PA machines in 8.0x ?
I know about FDC/FIC, etc.  but would like to flush the whole cache.
I also know about FDCE/FICE and about the lack of documentation on
their use.
