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 discussion. 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: http://sourceware.org/ml/gdb-patches/2012-05/msg00515.html (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! Maciej
