symbol versioning on libgcc?
I know that several libraries in FreeBSD uses symbol versioning. In looking through src/ I was unable to determine whether symbol versioning is used on libgcc. Any guidance would be appreciated. -- Steve ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

I had forgotten about objdump. A search for Symbol.map in src/ mislead me into believing the version was not happening. Further searching found the Makefile chuck that builds the map in src/gnu/lib/libgcc/Makefile. -- Steve ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Any guidance would be appreciated. I don't think it is. I haven't poked at any sources, but there are no FBSD* symbols in /usr/lib/libgcc_s.so, which is what's used in symbol versioning in, say, /lib/libc.so.7. -Boris ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Just for the record. What FBSD* symbol versions have to do with the library independently versioned by FSF? My interpretation of the question was whether libgcc used FreeBSD symbol versioning. If that wasn't it, then indeed, one has nothing to do with the other. -Boris ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

I'm trying to test a gfortran 4.6.0 patch that implements REAL(16), which means that TFmode needs to be supported. The GCC infrastructure currently does not build with TFmode on FreeBSD, and so a patch has been created. The last item that needs attention is symbol versioning.
