Subject: [gentoo-dev] make.conf optimization flags for k6, athlon
Date: Fri Jul 13 14:36:02 2001	[thread overview]
Message-ID: <01071323350502.00707@localhost> (raw)

Hi all,

In make.conf we specify the optimization CXXFLAGS as follows:

# For Pentium and k6/2 machines 
# -----------------------------

#CHOST="i586-pc-linux-gnu"
#CFLAGS="-mpentium -march=pentium -O3 -pipe"
#CXXFLAGS="-mpentium -march=pentium -O3 -pipe"

Why don't we use -march=k6 -mcpu=k6? Wouldn't that allow use of mmx and 
3dnow, which a generic pentium doesn't have?


# For PII PIII and Athlon machines
# --------------------------------

#CHOST="i686-pc-linux-gnu"
#CFLAGS="-mpentiumpro -march=pentiumpro -O3 -pipe"
#CXXFLAGS="-mpentiumpro -march=pentiumpro -O3 -pipe"

The same here: I believe (though I'm not sure as I don't have an Athlon) that 
the flags -mcpu=athlon -march=athlon might be of use.
