    libgcc/ChangeLog:

            PR gcov-profile/99105
            * libgcov-driver.c (write_top_counters): Rename to ...
            (write_topn_counters): ... this.
            (write_one_data): Pre-allocate buffer for number of items
            in the corresponding linked lists.
            * libgcov.h (malloc_mmap): New function.
            (allocate_gcov_kvp): Use it.

    gcc/testsuite/ChangeLog:

            PR gcov-profile/99105
            * gcc.dg/tree-prof/indir-call-prof-malloc.c: Use profile
            correction as the wrapped malloc is called one more time
            from libgcov.
            * gcc.dg/tree-prof/pr97461.c: Likewise.
