Re: ACATS Target Requirement Question

[Joel Sherrill <joel dot sherrill at oarcorp dot com>]

Well I guess running the ACATS gives a big hint.  There were not many
failures on sh-rtems4.10 and some of those were illegal memory accesses.
So only the c4* and cxa* are likely to be related to not having a real
clock tick.

sh-rtems4.10-gcc (GCC) 4.4.0 20080918 (experimental) [trunk revision 140475]
