 |
|
Hello All,
I've got System x3650 (7979) with Quad-Core Intel Xeon Processor E5310 (1.60GHz 1066MHz FSB)
What should be the optimized (best or safe) values for this type of processor?

CHOST=?
CFLAGS=?
CXXFLAGS=?

This one seems to be the right one:
Intel Core 2 Duo/Quad / Xeon 51xx/53xx
vendor_id : GenuineIntel
cpu family : 6
model : 15
model name : Intel(R) Core(TM)2 CPU XXXX @ XXXGHz
32 bit profile (x86)
CHOST="i686-pc-linux-gnu"
CFLAGS="-march=prescott -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="${CFLAGS}" |
