23644 – IA-64 hardware models and configuration options documentation error for 3.4.x and 4.0.x (original) (raw)

Description David H. Gutteridge 2005-08-30 21:19:02 UTC

Hello,

I've filed this under web, though obviously it applies to your info pages as well, I assume you generate everything from the same source, so this may be better filed somewhere else. (How come you don't have a documentation component to choose for bug reports?)

For both gcc 3.4(.4) and 4.0(.1), under IA-64 options, your documentation states:

"-mtune-arch=cpu-type Tune the instruction scheduling for a particular CPU, Valid values are itanium, itanium1, merced, itanium2, and mckinley."

The correct option is specified as -mtune=cpu-type, as is noted here (under the IA-64 heading):

http://gcc.gnu.org/gcc-3.4/changes.html

"Tuning code for the Itanium 2 processor has been added. The generation of code tuned for Itanium 2 (option -mtune=itanium2) is enabled by default now. To generate code tuned for Itanium 1 the option -mtune=itanium1 should be used."

Regards,

David H. Gutteridge

(How come you don't have a documentation component to choose for bug reports?)

Because that would not make sense as there is a keyword for documentation and documentation belongs to the component maintainer.

Fixed on the gcc-3.4.x branch, the gcc-4.0.x branch, and mainline (gcc-4.1).
