Про то, как самому собрать, написано в lfsbook c http://www.linuxfromscratch.org/lfs/
У книги есть перевод на русский, поищите. Знаю одно: собирать всё очень долго, оптимизировать можно далеко не всё. Лучшим решением будет пересобрать ядро, указав тип процессора, и, если вы любитель KDE или Gnome, пересобрать их с небольшой оптимизацией.
Цитата(Alexandr87 @ 2.3.2006, 17:28  ) | | Может глупость скажу, но до этого момента думал - что собственно нужно просто скомпилировать исходники 64-битным компилятором. |
На сколько я знаю, любым поддерживающем оптимизацию. У gcc есть флажки -mtune, -march, -mcpu...
Отрывок из мануфла к gcc:
| Цитата |
-mtune=cpu-type
Tune to cpu-type everything applicable about the generated code,
except for the ABI and the set of available instructions. The
choices for cpu-type are:
i386
Original Intel's i386 CPU.
i486
Intel's i486 CPU. (No scheduling is implemented for this
chip.)
i586, pentium
Intel Pentium CPU with no MMX support.
pentium-mmx
Intel PentiumMMX CPU based on Pentium core with MMX instruction
set support.
i686, pentiumpro
Intel PentiumPro CPU.
pentium2
Intel Pentium2 CPU based on PentiumPro core with MMX instruc-
tion set support.
pentium3, pentium3m
Intel Pentium3 CPU based on PentiumPro core with MMX and SSE
instruction set support.
pentium-m
Low power version of Intel Pentium3 CPU with MMX, SSE and SSE2
instruction set support. Used by Centrino notebooks.
pentium4, pentium4m
Intel Pentium4 CPU with MMX, SSE and SSE2 instruction set sup-
port.
prescott
Improved version of Intel Pentium4 CPU with MMX, SSE, SSE2 and
SSE3 instruction set support.
nocona
Improved version of Intel Pentium4 CPU with 64-bit extensions,
MMX, SSE, SSE2 and SSE3 instruction set support.
lines 7011-7033
k6 AMD K6 CPU with MMX instruction set support.
k6-2, k6-3
Improved versions of AMD K6 CPU with MMX and 3dNOW! instruction
set support.
athlon, athlon-tbird
AMD Athlon CPU with MMX, 3dNOW!, enhanced 3dNOW! and SSE
prefetch instructions support.
athlon-4, athlon-xp, athlon-mp
Improved AMD Athlon CPU with MMX, 3dNOW!, enhanced 3dNOW! and
full SSE instruction set support.
k8, opteron, athlon64, athlon-fx
AMD K8 core based CPUs with x86-64 instruction set support.
(This supersets MMX, SSE, SSE2, 3dNOW!, enhanced 3dNOW! and
64-bit instruction set extensions.)
winchip-c6
IDT Winchip C6 CPU, dealt in same way as i486 with additional
MMX instruction set support.
winchip2
IDT Winchip2 CPU, dealt in same way as i486 with additional MMX
and 3dNOW! instruction set support.
c3 Via C3 CPU with MMX and 3dNOW! instruction set support. (No
scheduling is implemented for this chip.)
c3-2
Via C3-2 CPU with MMX and SSE instruction set support. (No
scheduling is implemented for this chip.)
While picking a specific cpu-type will schedule things appropri-
ately for that particular chip, the compiler will not generate any
code that does not run on the i386 without the -march=cpu-type
option being used.
-march=cpu-type
Generate instructions for the machine type cpu-type. The choices
for cpu-type are the same as for -mtune. Moreover, specifying
-march=cpu-type implies -mtune=cpu-type.
-mcpu=cpu-type
A deprecated synonym for -mtune.
-mfpmath=unit
Generate floating point arithmetics for selected unit unit. The
choices for unit are:
sse,387
