Hi,
I'm running a mac pro with darwin 8.8.1 osx 10.4.8. 3.0ghz Woodcrest
dual core xeon
chip with 1.33ghz bus.
I have gcc 4.0.3 from hpc and 4.1.1 from apple.
What I would like to know is, what is my -(m)arch and besides -03, how
can I invoke auto loop vectorization -sse3 etc, or can I since I don't
see my arch. I have intels specific gnu friendly compilers, however
they are not that friendly and would like to stick with gcc.
Any comments or ideas would be greatly appreciated.
Thank you,
Conor
