After reading some docs, the impression I get is that the 'nocona'
flag is for building a 64-bit system... For a 32-bit system, it seems
like 'prescott' would be the choice, wouldn't it?
This from the GCC website about 4.2.0 release changes:
IA-32/x86-64
* -mtune=generic can now be used to generate code running well on
common x86 chips. This includes AMD Athlon, AMD Opteron, Intel
Pentium-M, Intel Pentium 4 and Intel Core 2.
* -mtune=native and -march=native will produce code optimized for
the host architecture as detected using the cpuid instruction.
* Added a new command line option -fstackrealign and and
__attribute__ ((force_align_arg_pointer)) to realign the stack at
runtime. This allows functions compiled with a vector-aligned stack to
be invoked from legacy objects that keep only word-alignment.
We don't have gcc-4.2.0 in our portage available for installation yet,
do we? Anyone know when?
