Hi,
I'm building code on an Intel Core Duo, working on getting it speed-
optimized. So far I get the best results when I use '-march=pentium4'
for the architecture (using GCC 4.0). What architecture should I use
though, if I need to share this code with someone on an Intel Core 2
machine, i.e. a Mac Pro?
I've been having a hard time nailing down all the various
architecture terms for Intel Core Duo vs. the Core 2 line, but I know
the Core Duo is based on the Pentium M, whereas the Core 2 line is
based on the Intel Core microarchiecture. If someone has a doc
somewhere with a comprehensive overview of the various names, codes,
brandnames, etc. for the various Intel processors used by Apple,
please point me there, that'd be a great help.
Cheers,
Michael
