While platform bugs typically require fixes in platform-specific code, I would think we would want to stay away from bugfixes in minor platforms during stage 4. The wording seems to say that I could fix wrong-code bugs in pdp11 during stage 4; I have been assuming I should not do that. Is this something that should be explicitly stated?
I think it's somewhere stated that during Stage 3 non-primary/secondary
targets as well as non-C/C++ languages have no restrictions. Of course
while technically true breaking builds is still not wanted.
For Stage 4 things are somewhat different I think, not sure if it's
anywhere spelled out.
Richard.
