Subject:         * config/tc-hppa.c (UNWIND_SECTION_NAME): Define for ELF.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=46031ca9e4766d46f34681c6483739ee746baee5;p=binutils-gdb.git

    * config/tc-hppa.c (UNWIND_SECTION_NAME): Define for ELF.
        (pa_build_unwind_subspace): Remove #if 0 wrapper.  Select a
        suitable relocation based on the size of the target's pointer.
        Always Use subsegment zero for the unwinders.
        (pa_level): Handle "2.0w".
