Take the following code:
void bar (const int * const x);
static const int y[];
void
foo (void)
{
bar (y);
}
This should at assemble but does not.
If I get some time this weekend I will look into fixing this.

Also one more note, this was able to compile with 3.3.2 but we called y as an extern symbol which is just wrong also. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19315 ^ permalink raw reply [flat|nested] 5+ messages in thread

This looks like another undocumened extension and how it works too. Reading the comment in c-decl.c says this is how it should work but this is just plainly stupid: /* If a `static' var's size isn't known, make it extern as well as static, so it does not get allocated. If it is not `static', then do not mark extern; finish_incomplete_decl will give it a default size and it will get allocated. */ -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19315 ^ permalink raw reply [flat|nested] 5+ messages in thread
