[cfe-dev] Question about -Wreadonly-setter-attrs

[David Chisnall]

I disagree on this one.  -Wreadonly-setter-attrs warns that you have  
written something that may be redundant.  This is pedantic.  In  
contrast, -Wundeclared-selector warns that you have written something  
that may be generating code that will corrupt your stack.  This is  
important.  Pedantic warnings should not be in the default set,  
important ones should.
