[Bug ld/4398] New: relocation R_X86_64_PC32 against 'funcx'; recompile with -fPIC

[evilight at gmail dot com]

Product: binutils
Version: 2.16,2.17
Component: ld
OS: SUSE Linux Enterprise Server 10 (x86_64) - Kernel 2.6.16.21-0.8-smp (64-
bit)


    when I link some object files ,which some of them are compiled by gcc4.1.0 
from c code, and others are assemble code compiled by as, while ld them to a 
shared library. a error will occur like this:


as -o a.o a.s
gcc -fPIC -o b.o -c b.c
ld -shared a.o b.o -o libtest.so
ld: a.o: relocation R_X86_64_PC32 against `int_this_is_a_test_k8_64_body' can 
not be used when making a shared object; recompile with -fPIC
ld: final link failed: Bad value
make: *** [libtest.so] Error 1

and if works with ld from binutils 2.15, it's fine.

here is my code:
====================================b.c========================================
int hereitis()
{
int_this_is_a_test_k8_64_body();
return 1;
}
===============================================================================

        .type   int_this_is_a_test_k8_64_body,@function

        ret

        .size   int_this_is_a_test_k8_64_body,.this_is_a_test_k8_64_body_end-
