Hi Juergen:
As near as I can tell from the documentation, all of those options
simply allow the compiler to generate the code, it won't necessarily
do so unless you either write specific code, or you use a flag like -
ftree-vectorize. Another possibility is that the compiler simply
didn't find a location in the program where use of SPE options was
practical/useful. I'd imagine that the automatic compiler use of
these options is rather limited.
Anyone else have any thoughts?

Hi !!
I use the gcc for the PowerPC with the options -mspe=yes, -
misel=yes and -mabi=spe all these nice option didn't show any
difference to the compilation without. So my question is did I need
to develop some special code for these option ( like use some
special types for the SPE engine) or is something wrong with my
compiler ?
Thank you for your help
