This patch is a part of PR20218. 4.1/4.2 PATCH: PR middle-end/20218: Can't use __attribute__ ((visibility (hidden))) to hide a symbol I could remove this patch altogether.

Re: [parisc-linux] glibc is broken because of gcc
I could remove this patch altogether. But I still wonder why this patch works ok on other archs and not on hppa*. hppa* does a deferred generation of plabels for indirect function calls. I think this is affected by the change. I don't recall exactly but there may have been a followup patch to fix this. Of course, this change isn't in the 4.1 GCC tree. Dave -- J.

I just have to figure out what it means now ;-). Can I find this patch somewhere ? Is there any discussion on the ML ? The patch was discussed near January of this year on the gcc ML. Dave -- J.

David Anglin [EMAIL PROTECTED] National Research Council of Canada (613) 990-0752 (FAX: 952-6602) Ok, I nailed it. I removed PR20218 patch and generated a 4.1.2-12+b1 then build glibc. Glibc build is ok now. I think the hppa toolchain can move on and build the glibc-2.5-11 and then rebuild the portmap and all pie executable (pfeww... what a bug chain).
