[Bug binutils/435] New: The relocation bug

[zhanrk at 163 dot com]

Here is my toolchains version:
  - binutils-2.13
  - gcc-core-3.4.0

And i use the following commands to build my frv-elf toolchain from the source
packages:

  - binutils-2.13:
  configure --prefix=/usr/local/frv-elf-toolch --target=frv-elf

  - gcc-core-3.4.0:
  configure --prefix=/usr/local/frv-elf-toolch \
           --target=frv-elf --without-headers --with-newlib \
           --disable-shared --disable-threads --enable-languages=c

This relocation bug is a little hidden, it seems that it only appears when
linking a very large program. In my test case, there is a const string in
frv-linux-2.6.4/init/version.c:

    const char *linux_banner = "Linux version 2.6.4 ...";

By disassembly analysis, we can kown the address in the '.rodata' section of the
string "Linux version 2.6.4 ..." is 0xd299c. While the value of the pointer
variable 'linux_banner' is 0xd29a0. So if i use the following function to print
this string:

    printk(linux_banner);

i alway get the string "x version 2.6.4 ..." on my virtual terminal !!!
