Hello,
I would like to propose the activation by default of -Wreturn-type.
The main objective would to provide a warning for such code:
int foo() {
return;
}
For now, it is only enabled when we have -Wall:
$ gcc -c foo.c
$ gcc -Wall -c foo.c
foo.c: In function ‘foo’:
foo.c:2:2: warning:

Over the last few weeks, working with Jonathan, I have been running
daily analysis of Coverity (a proprietary static analyzer tool)
It is running on a Debian amd64 with the options:
--with-gnu-as --with-gnu-ld --disable-bootstrap
--enable-languages=jit,c,c++,fortran,lto,objc --enable-host-shared
Hello,
I have been trying to build the llvm toolchain with gcc 7.2 using the
Debian packages.
However, it is currently failing with some undefined reference.
Seems that some symbols are removed during the build phase (too strong
