Hello,I've filed this under web, though obviously it applies to your info pages aswell, I assume you generate everything from the same source, so this may bebetter filed somewhere else. (How come you don't have a documentation componentto 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 areitanium, itanium1, merced, itanium2, and mckinley."The correct option is specified as -mtune=cpu-type, as is noted here (under theIA-64 heading):http://gcc.gnu.org/gcc-3.4/changes.html"Tuning code for the Itanium 2 processor has been added. The generation of codetuned for Itanium 2 (option -mtune=itanium2) is enabled by default now. Togenerate code tuned for Itanium 1 the option -mtune=itanium1 should be used."Regards,David H. Gutteridge
