crosstool-ng: patches/glibc/2.6/glibc-2.3.6-allow-gcc-4.0-elf.patch@90fefc8790fb

     1 From http://www.mail-archive.com/pld-cvs-commit@pld-linux.org/msg00229.html

     2 Fixes

     3   rtld.c: In function '_dl_start':

     4   dynamic-link.h:47: error: nested function 'elf_machine_rela_relative' declared but never defined

     5   dynamic-link.h:41: error: nested function 'elf_machine_rela' declared but never defined

     6 when compiling glibc-2.3.4 with gcc-4.0

     8 But see also

     9 http://sources.redhat.com/ml/libc-hacker/2005-02/msg00000.html

    10 and

    11 http://sources.redhat.com/ml/libc-hacker/2005-03/msg00008.html

    12 which seem to propose less radical fixes?

    14 Aha.  See also http://sources.redhat.com/bugzilla/show_bug.cgi?id=721

    26 -   relocated address is properly aligned, whereas the compiler is

    27 -   entitled to assume that a pointer to a type is properly aligned for

    28 -   the type.  Even if we cast the pointer back to some other type with

    29 -   less strict alignment requirements, the compiler might still

    30 -   remember that the pointer was originally more aligned, thereby

    31 -   optimizing away alignment tests or using word instructions for
