System: Linux decomino 2.2.17 #1 Mon Sep 4 20:22:16 UTC 2000 i686 unknown
Architecture: i686
host: i686-pc-linux-gnu
build: i686-pc-linux-gnu
target: i686-pc-linux-gnu
>Description:
I noticed that the C++ compiler does not support the GCC option
-Wmissing-noreturn. However, this seems not to be documented
anywhere; the option is silently ignored.
>How-To-Repeat:
Compile the following code with -Wmissing-noreturn as both C and C++.
Notice that a warning is only given when compiled as C.
#include <stdlib.h>
void
foo (void)
{
exit (0);
}
>Fix:
In decreasing order of preference:
(1) Find some place where the code for this warning can be shared
between C and C++, and implement the warning there; or
(2) Implement it separately in the C++ compiler; or
(3) Document that it is a C-specific warning.
