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.
