Description Gavin 2005-07-24 11:55:10 UTC

Many people use -Os instead of -O2 for their glibc.

Durons, Celerons, and Semprons often yield better benchmark scores using glibc
compiled with -Os.  Unfortunately, I have to hack up the Glibc ebuild every time
I want to upgrade my glibc.

celerons do not *need* -Oanything. i have used -O2, -O3, and -Os with mine, and
none of them gave any problems.

check out /etc/make.conf for the CFLAGS your system uses. i'm not going to
close, but i vote INVALID

the glibc ebuild forces -O2

I'm going to interpret Spanky's response to mean we aren't going to change this.
 If I'm wrong, why hasn't it been done by now? :)
