Subject:         * paread.c (read_unwind_info)
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d64956faaf563b18d45b550c643c7a3442899581;p=binutils-gdb.git

    * paread.c (read_unwind_info)

        * paread.c (pa_symtab_read): Update the "check_strange_names"
        filter to match GCC's current output.  Filter out section symbols
        (which the HP linker sometimes puts in the wrong place).
