GCC default targets on sparc

GCC default targets on sparc

[Jan Engelhardt]

Hi,


When gcc is ./configured with -mcpu=ultrasparc, it emits -m64 objects by 
default, when it's with -mcpu=v8, it emits V8 -m32 objects. How would 
one configure it to emit V9 -m32 by default?


thanks
Jan

	I use -mv8plus or -mtune=niagara -mcpu=niagara and gcc creates 32 bits 
objects.

Oops. It should have read:

	./configure --with-cpu=ultrasparc

Not -mcpu or -mtune.

	I use this options and I obtain by default :

tchaikovski:[/usr/local/lib] > file libSDL.so
libSDL.so:      ELF 32 bits MSB bibliothèque dynamique SPARC32PLUS 
Version 1, V8+ requis, avec liens dynamiques, fichier intégral

on a T1000 server running Solaris. For information :

Using built-in specs.

	This compiler can build 32 and 64 bits objects with -m32 and -m64 options.
