With option '-pedantic', they warn, yes:
$ cat foo.c
extern void foobar (int);
void foo (int x) { return foobar (x); }
$ gcc -Wall -S -pedantic foo.c
foo.c: In function ‘foo’:
foo.c:2:27: warning: ISO C forbids ‘return’ with expression, in function
returning void [-Wpedantic]
2 | void foo (int x) { return foobar (x); }
| ^~~~~~~~~~
$ clang -Wall -S -pedantic foo.c
foo.c:2:20: warning: void function 'foo' should not return void expression
[-Wpedantic]
2 | void foo (int x) { return foobar (x); }
| ^ ~~~~~~~~~~
I thought that 'return' of a void expression was documented as a GCC
extension. But I can't find it in the documentation now.
