15 # ==============================
18 # package (and in some cases the libraries it uses) at default optimizations
19 # before reporting errors to developers.
21 -# Please refer to the GCC manual for a list of possible values.
22 +# -mtune=<cpu-type> for PowerPC64 systems instructs the gcc compiler that
23 +# it can use instruction scheduling specific for that type of processor
26 +# -mcpu=<cpu-type> for PowerPC64 systems selects the type of processor you want
27 +# to optimize your code for. Code generated under those options will run best
30 +# -mcpu=<cpu-type> and -mtune=<cpu-type> should both be specified
32 +# GCC 3.x supports many ppc64 processor types including: power3, power4,
33 +# 970 (aka G5), and power5.
35 +# RS64 processors should specify power3.
37 +# Additional options of interest:
39 +# -maltivec enables optional altivec support and should be used
40 +# only for 970 processors. It also requires that you have
41 +# the alitvec option compiled into your kernel to take full advantage of this
42 +# feature. Note: you should also include -mabi=altivec flag if using this option.
45 +# -O3 for the most part seems ok but should be used with caution as
46 +# for instance app-editors/vim has problems if it is used. -O2 is a
49 +#Example CFLAGS setting
50 +#CFLAGS="-O2 -pipe -mcpu=970 -mtune=970 -maltivec -mabi=altivec"
54 +#CFLAGS="-O2 -pipe -mcpu=power3 -mtune=power3"
56 # If you set a CFLAGS above, then this line will set your default C++ flags to
59 # DO NOT PUT ANYTHING BUT YOUR SPECIFIC ~ARCHITECTURE IN THE LIST.
60 # IF YOU ARE UNSURE OF YOUR ARCH, OR THE IMPLICATIONS, DO NOT MODIFY THIS.

64 +# system. If you want the testing things update after these steps are completed.
