So, it is nice if an entire newlib port can be done, then, you don’t have to
worry about subsets of it.
I think the patch is Ok, I would change:
+#ifndef __nvptx__
fprintf (stderr, "Test failed: %s\n", msg);
+#endif
to just comment out the line.
If you want to try your hand at removing stdio in some fashion, you can try, I
am skeptical that there is a meaningful way to do that and it seems larger and
harder then the patch you have. The usual fashion I would recommend would be a
stub library for testing that simply disappears such calls as uninteresting.
int fpritnf (…) { return 0; } would go a long way. For test cases that someone
care about what fprintf actually does, those can be marked as stdio and likely,
those would be a far smaller set to so mark.
