--- Comment #10 from Dmitry Gorbachev <d.g.gorbachev at gmail dot com> 2011-02-24 16:27:53 UTC --- Yes, ld.gold and ld.dk silently use non-LTO part of div.o; it's a bug. However, I don't think that an undefined reference error is not a bug. 1. The testcase compiles well without -flto or with -fno-use-linker-plugin. 2. Imagine a bare-metal program, such as a kernel. When building it, the standard C library is not used, and compiler-generated calls to memcmp, etc. are resolved within the program itself. To work around the bug, a library with these functions must be compiled without -flto. Again, an unpleasant thing is that the order of linking with LTO differ from one without LTO, and linkers disagree with each other on this matter. P.S.: Will ld.hjl be obsoleted by ld.dk? If yes, perhaps fixing it does not worth a trouble... -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
