Saving extension semantic values from collection
- To: gcc-patches at gcc dot gnu dot org
- Subject: Saving extension semantic values from collection
- From: "Martin v. Loewis" <martin at loewis dot home dot cs dot tu-berlin dot de>
- Date: Mon, 20 Mar 2000 14:24:58 +0100
I just commited the appended patch; it prevents the integers used to
save the warn flags from being garbage-collected.
GCC was successfully bootstrapped and tested on i586-pc-linux-gnu with
this patch.
Regards,
Martin
2000-03-20 Martin v. Löwis <loewis@informatik.hu-berlin.de>
* c-parse.in (SAVE_WARN_FLAGS): Use size_int.
* c-parse.y, c-parse.c, objc/objc-parse.y, objc/objc-parse.c:
Regenerated.
