The first CFLAGS (or CXXFLAGS) line below appears to be taken from the environment setting, and the second is from the "<packagename> was built with the following" section of the emerge --info output.
Squid looks as it should (the -flto is added to that package only) but for firefox it appears that -O2 has been stripped, and not replaced with -O3, which IIRC is the default for that package. # grep ^CFL /etc/make.conf CFLAGS="-march=amdfam10 -mcx16 -msahf -mpopcnt -mabm -O2 -pipe" # emerge --info squid | grep ^CFL CFLAGS="-march=amdfam10 -mcx16 -msahf -mpopcnt -mabm -O2 -pipe" CFLAGS="-march=amdfam10 -mcx16 -msahf -mpopcnt -mabm -O2 -pipe -flto" # emerge --info firefox | grep ^CFL CFLAGS="-march=amdfam10 -mcx16 -msahf -mpopcnt -mabm -O2 -pipe" CFLAGS="-march=amdfam10 -pipe -mno-avx" Is anyone getting O2 or O3 in their emerge --info firefox output?
