This matches with my memory, but ...
1. I don't recall any consensus on abandoning QImode!=8bits.
AFAIK, the c4x is the only platform w/ QImode !=8bit in GCC, which
causes your patch to abandoning the only testing platform for such
Are you wanting to abandon QImode != 8bit? This, IMO would qualify as a
serious design defect in GCC (Admitted, we all know GCC has problems
related to this, but abandoning it and means loss of generality)
2. tic4x-gcc-3.4.x is buildable, tic4x-gcc-4.x had never built.
i.e. actually a regression has occurred sometime between 3.4.x and 4.0,
which had slipped through GCC-regression testing cracks.

IMHO: No, you are going too far.
.. As well I consider Mark to be going too far in "nodding off" this
