* [Bug target/19315] New: variable is not emitted in the asm @ 2005-01-07 15:48 pinskia at gcc dot gnu dot org 2005-01-07 16:07 ` [Bug target/19315] " schwab at suse dot de ` (3 more replies) 0 siblings, 4 replies; 5+ messages in thread From: pinskia at gcc dot gnu dot org @ 2005-01-07 15:48 UTC (permalink / raw) To: gcc-bugs 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.

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
