Did you compare the generated code?
Nope, but that's a good idea. I'll compile and objdump the various scenarios next year.
I just did this - this is always pretty instructive in such situ- ations. GCC-4.x optimizes much better, but will also unremorsefully punish even small sins like a forgotten "volatile".

That's nearly 10% difference in code size...
But here the difference is not in this function - both compile to exactly the same code. Obviously some other functions in the CFI driver are different, though.
Merry Christmas from a very bad quoting net citizen. :P
Thanks, and Merry Christmas, too.
Best regards,
