Okay, I brought this all about - wow! - so I really feel I should be
doing something here. Unfortunately, I'm not able to fully comprehend
this whole conversation; I'm really not at all familiar with the inner
workings of either gcc or newlib, and this is my first foray into the
PowerPC world. So I certainly don't understand all the ramifications of
what you all are discussing.
However, I can look at the instructions being generated, though I could
use a few pointers on what specifically to look for - specific
instructions, you know. Unfortunately I won't be able to do that until
Tuesday at the earliest, as I am off on other projects until then, and
don't have access to my tools. All I do have right now is the
executable; if someone can look at it quickly and wishes to do so, then
by all means, let me know and I'll send it to you. Otherwise, it seems
the ball's in my court, and will have to remain there until Tuesday.
Sorry about the unfortunate timing!
Thanks for all the input!
P.S. Enjoy your weekends!
