Hi,
The compile farm machine gcc41 is a Merced based machine:
guerby@gcc41:~/build/gcc$ cat /proc/cpuinfo
processor : 0
vendor : GenuineIntel
arch : IA-64
family : 7
model : 0
model name : Merced
revision : 6
archrev : 0
features : standard
cpu number : 0
cpu regs : 4
cpu MHz : 733.441
itc MHz : 733.441016
BogoMIPS : 731.13
siblings : 1
And provides 4.4 testresults, latest looks good:
http://gcc.gnu.org/ml/gcc-testresults/2009-03/msg02027.html
We also have a Madison machine gcc60:
guerby@gcc60:~$ cat /proc/cpuinfo
processor : 0
vendor : GenuineIntel
arch : IA-64
family : 31
model : 1
model name : Madison
revision : 5
archrev : 0
features : branchlong
cpu number : 0
cpu regs : 4
cpu MHz : 1300.000
itc MHz : 1300.000000
BogoMIPS : 1946.41
siblings : 1
Now I don't know if gcc41 falls in your -mtune=itanium1 category
or not.
That said if it does I don't oppose removing itanium1, we'll just turn
off the gcc41 machine when the 4.4 branch last release is done.
Sincerely,
Laurent
