Subject: Warn for extern prototypes
Date: Wed, 30 Apr 2014 22:07:30 +0200 [thread overview]
Message-ID: <20140430200730.GA11100@ravnborg.org> (raw)
Hi all.
Is it possible to get a warning when sparse encounter a
function prototype declared using "extern"?
So the following code:
extern void foo(void);
void bar(int x);
Would generate warnings because the declaration of foo()
uses extern.
I took a very short peek at evaluate.c - but decided to ask as maybe
there is already something that I overlooked or it is maybe trivial.
The rationale behind this is that at least in some areas of the kernel,
the use of "extern" for prototypes are no longer accepted.
A sparse warnings would be good to tell me all the cases I missed
in the conversion.
Sam
