 Ouch, that's a tad inconvenient to me, I had hoped for the branch to have 
been made so that the MIPS changes I'm working on right now can be safely 
applied to trunk without the risk of disturbing the upcoming release.  
That includes the floating-point changes currently on my plate -- these 
already published and some more stuff still ongoing.  Plus the ISA bit 

 I do understand the importance of the issues concerned by Jan of course, 
but I also feel like deferring the MIPS stuff for a month and likely more 
is going to get me distracted too much by something else, so given the 
circumstances may I kindly ask people to have a look into my proposal and 
request for discussion about the generic parts of the ISA bit changes as 
posted here:

(of course any comments about the MIPS parts are welcome as well, but 
these bits I am pretty much confident about).

 While this is still possibly too brave a change to be included in 7.5 at 
such a short notice, I think it will make sense to start the discussion 
now rather than later, so that it won't be another month after 7.5 has 
branched before it can finally go in.  Thanks!
