Re: Re: patch: don't issue -Wreorder warnings when order doesn't matter
Quoting Jonathan Wakely <jwakely.gcc@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.
