Hi, just tried -ffunction-sections -Wl,--gc-sections on F15 xulrunner and got libxul.so 24947928 -> 23631640 (5.28% gain) and it still works. ld.gold --icf is a different optimization but that one requires gold. Are there some serious Bugs why Fedora is not using it? Thanks, Jan -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
