Quoting Jonathan Wakely <jwakely....@gmail.com>:
I would object to changing the behaviour, or if it changes then it should be controllable so I can continue to get the current behaviour, e.g. -Wreorder=0 does what you propose, -Wreorder=1 does what we have now, and -Wreorder is equivalent to -Wreorder=1
That sounds somewhat obscure (e.g. why isn't -Wreorder=0 the same as -Wno-reorder), and at some point people might demand negative values for more discriminating checks and floating point values for in-between choices. I think more descriptive would be: -Wreorder=nonconst and -Wreorder=any If someone miraculously cheats Rice's theorem, or wants to propose to get as close as possible to tell if reordering has a semantic effect as is feasible to tell in a compiler, you could call it -Wreorder=relevant or somesuch.
