Subject:         * emulparms/elf64hppa.sh (OTHER_READONLY_SECTIONS): Put stubs before
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=904ecb2d787a2b9e501232d4e3852dc9659fca77;p=binutils-gdb.git

    * emulparms/elf64hppa.sh (OTHER_READONLY_SECTIONS): Put stubs before
        unwinders so that they are closer to the text section.
        (OTHER_BSS_SECTIONS): Define.
        (EXECUTABLE_SYMBOLS): Provide __SYSTEM_ID and _FPU_STATUS.
        (INIT_START, INIT_END): Define.
        (FINI_START, FINI_END): Define.
        * scripttempl/elf.sc: Add support for INIT_START, INIT_END,
        FINI_START, FINI_END and OTHER_BSS_SECTIONS.
