    scripts/recordmcount.pl: support data in text section on powerpc · 2e50c4be
    Ulrich Weigand authored
    If a text section starts out with a data blob before the first
    function start label, disassembly parsing doing in recordmcount.pl
    gets confused on powerpc, leading to creation of corrupted module
    This was not a problem so far since the compiler would never create
    such text sections.  However, this has changed with a recent change
    in GCC 6 to support distances of > 2GB between a function and its
    assoicated TOC in the ELFv2 ABI, exposing this problem.
    There is already code in recordmcount.pl to handle such data blobs
    on the sparc64 platform.  This patch uses the same method to handle
    those on powerpc as well.
