CPUTYPE for Sempron
Which CPUTYPE should be used for the AMD Sempron CPU? I'm assuming this is similiar to an athlon-xp. Perhaps an alias or a new entry should be created for this CPU? --- CPU: AMD Sempron(tm) Processor 3000+ (1799.81-MHz 686-class CPU) Origin = AuthenticAMD Id = 0x10fc0 Stepping = 0 Features=0x78bfbffFPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CLFLUSH,MMX,FXSR,SSE,SSE2 AMD Features=0xc050NX,AMIE,DSP,3DNow! ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]
Re: CPUTYPE for Sempron
Hello, use CFLAGS=-march=atlhlon-xp. CPUTYPE overrides CFLAGS, so it doesn't provide You such sophisticated optimizations. If You plan to make buildworld, use: CFLAGS=-O2 -pipe -march=athlon-xp Anyway, if You just use ports collection, and don't make buildworld CFLAGS=-O3 -pipe -march=athlon-xp is also reliable, but it might make some trouble when making buildworld.

If You plan to make buildworld, use:

Anyway, if You just use ports collection, and don't make buildworld
CFLAGS=-O3 -pipe -march=athlon-xp
is also reliable, but it might make some trouble when making buildworld.
CPUTYPE doesn't override CFLAGS. Read /usr/share/mk/bsd.cpu.mk.
Specifically, the second to last line:
CFLAGS += ${_CPUCFLAGS}
Earlier in the file you see:
_CPUCFLAGS = -march=${CPUTYPE}
So in effect what is happening:
CFLAGS += -march=athlon-xp
I use the following with no issues on 5.x and CURRENT:
CPUTYPE ?= athlon-xp
CFLAGS = -O2 -fno-strict-aliasing -pipe
COPTFLAGS = -O2 -fno-strict-aliasing -pipe
