Thank you. > You can define STACK_SIZE while running the tests. That will disable > some large tests.

I cannot find any site.exp file. Can you give me a tree example for another arch? I did not find anything looking like defining target_info in .exp files but only using target_info. Where should I add a board support file? > The testsuite also supports a dg-require framework.

I found that in target-supports.exp: proc check_effective_target_int32plus { } { return [check_no_compiler_messages int32plus object { int dummy[sizeof (int) >= 4 ? 1 : -1]; }] } Is it cross-compiled and executed code? Because execution is not configured (simulator not configured). Regards. Florent
