Validation of gcc tools

[David Brown]

The question of development tools for various targets comes up regularly 
on comp.arch.embedded.  It can often lead to disagreements between users 
and supporters of gcc, and those who feel that only commercial closed 
source tools are good enough for professional use.  One of the key 
arguments from the closed-source camps is that they have tools that are 
validated and certified with Plum Hall and other such validation suites. 
  Does anyone know if gcc has passed such validations, and for which 
targets and versions?

mvh.,
