In /usr/src/linux/Makefile:
CFLAGS = -Wall -Wstrict-prototypes -O6 -ffast-math \
-fno-strength-reduce -fno-exceptions -fcombine-222 -funroll-loops
In ~/arch/i386/Makefile:
ifdef CONFIG_M686
#CFLAGS := $(CFLAGS) -m486 -malign-loops=2 -malign-jumps=2 \
-malign-functions=2 -DCPU=686
CFLAGS := $(CFLAGS) -mamdk6 -march=amdk6 -malign-loops=2 \
-malign-jumps=2 -malign-functions=2 -DCPU=686
endif

Walaupun CPU dual PPro, tapi optimisasi untuk amdk6 menghasilkan
code yang lebih cepat 10-15% daripada:
-mpentiumpro -march=pentiumpro
Linux version 2.2.2 (*** concealed ***)
(gcc version pgcc-2.90.29 980515 (egcs-1.0.3 release)) #1 SMP
Wed Feb 24 09:30:53 JAVT 1999
Pgcc berbasis egcs 1.0.3 menghasilkan binary yang lebih cepat
daripada yang berbasis 1.1.x
