Hello group! I have a few questions regarding adding symbols to lib/libc/<arch>/Symbol.map, so that function signatures are exported: - what are the conventions regarding putting symbols in FBSD_X.Y or FBSDprivate_X.Y sections of the aforementioned files? - when it is necessary to bump X.Y numbers? - what is the difference between FBSD_X.Y and FBSDprivate_X.Y sections? The above questions arose from the discussion on freebsd-arm@ (http://lists.freebsd.org/pipermail/freebsd-arm/2012-June/003555.html) which concerns fixing Perl on ARM. The fix is to add __flt_rounds function signature to lib/libc/arm/Symbols.map. Regarding this fix it appears (after Symbols.map files analysis and checking their SVN history) that adding this symbol is just a bug fix and should be put to FBSD_1.0 section without incrementing numbers. But I don't have more in-depth explanation so sending this email. Anyone can comment on the above questions or point to some documentation (I've searched Developer's Handbook and Internet but found nothing)? Regards, Jan Siekahome | help
