After reading some docs, the impression I get is that the 'nocona' |
| 2 |
flag is for building a 64-bit system... For a 32-bit system, it seems |
| 3 |
like 'prescott' would be the choice, wouldn't it? |

This from the GCC website about 4.2.0 release changes: |
| 6 |
|
| 7 |
IA-32/x86-64 |
| 8 |
|
| 9 |
* -mtune=generic can now be used to generate code running well on |
| 10 |
common x86 chips. This includes AMD Athlon, AMD Opteron, Intel |
| 11 |
Pentium-M, Intel Pentium 4 and Intel Core 2. |
| 12 |
* -mtune=native and -march=native will produce code optimized for |
| 13 |
the host architecture as detected using the cpuid instruction. |
| 14 |
* Added a new command line option -fstackrealign and and |
| 15 |
__attribute__ ((force_align_arg_pointer)) to realign the stack at |
| 16 |
runtime. This allows functions compiled with a vector-aligned stack to |
| 17 |
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, |
| 20 |
do we? Anyone know when? |
