n00b question: What CHOST?

[bassvandijk]

I'm installing Gentoo Linux on a Pentium 166 Mhz.

I was wondering what to choose for the CHOST and CFLAGS variable.
Do I need i586 or pentium-mmx?

make.conf

Code: Select all

...
# CPU types supported in gcc-3.2 and higher: athlon-xp, athlon-mp,
# athlon-tbird, athlon, k6, k6-2, k6-3, i386, i486, i586 (Pentium), i686
# (PentiumPro), pentium, pentium-mmx, pentiumpro, pentium2 (Celeron),
# pentium3, and pentium4.
...

cat /proc/cpuinfo

Code: Select all

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 5
model           : 4
model name      : Pentium MMX
stepping        : 3
cpu MHz         : 166.451
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : yes
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 1
wp              : yes
flags           : fpu vme de pse tsc msr mce cx8 mmx
bogomips        : 331.77

EDIT:
I just read: http://www.freehackers.org/gentoo/gccfl ... _gcc3.html

So I think I go for:

Pentium MMX (Intel)
CHOST="i586-pc-linux-gnu"
CFLAGS="-march=pentium-mmx -O3 -pipe -fomit-frame-pointer"

Safe cflags:

Code: Select all

CHOST="i586-pc-linux-gnu"
CFLAGS="-march=pentium-mmx -O2 -pipe -fomit-frame-pointer"
CXXFLAGS="-march=pentium-mmx -O2 -pipe -fomit-frame-pointer"

[bassvandijk]

Thanks nixnut, I will go for that.

Not that you were doubting, but I can confirm these should be correct. 686 is PPro and above.
