A powerpc patch from Ronald Wahl:
Ok, now i got it after a day of work. I have had a look into glibc and found the following: sysdeps/powerpc/dl-machine.c: ... case R_PPC_JMP_SLOT: /* It used to be that elf_machine_fixup_plt was used here, but that doesn't work when ld.so relocates itself for the second time. On the bright side, there's no need to worry about thread-safety here. */ { Elf32_Sword delta = finaladdr - (Elf32_Word) reloc_addr; ... The comment made me suspicious. The same position in uClibc looks like this: ldso/ldso/powerpc/elfinterp.c: ... case R_PPC_JMP_SLOT: { unsigned long targ_addr = (unsigned long)_dl_linux_resolve; int delta = targ_addr - (unsigned long)reloc_addr; ... When I change it to the following it works: ... case R_PPC_JMP_SLOT: { unsigned long targ_addr = *reloc_addr; int delta = targ_addr - (unsigned long)reloc_addr; ... I hope it will not break anything. Can anyone review this change and commit it into CVS? thanks, ron
