sparc: Use ba,a,pt in PLTs and fix bugs in R_SPARC_JMP_IREL handling.
2010-03-03 David S. Miller <davem@davemloft.net> * sysdeps/sparc/sparc32/dl-machine.h (elf_machine_lazy_rel): Must pass '1' for 't' argument to sparc_fixup_plt. * sysdeps/sparc/sparc64/dl-machine.h (elf_machine_lazy_rel): Likewise. * sysdeps/sparc/sparc32/dl-plt.h (OPCODE_BA_PT): Define. (sparc_fixup_plt): Document 't' argument. Enable branch optimization and use v9 branches when possible. Explain why we cannot unconditionally patch the branch into the first PLT instruction. * sysdeps/sparc/sparc64/dl-plt.h (sparc64_fixup_plt): Document 't' argument. Use v9 branches when possible. Explain why we can in fact unconditionally use a branch in the first PLT instruction here.
