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? -- [EMAIL PROTECTED] mailing list
