-/* This file is used by targets whose makefiles define LIBGCC_SYNC
-   to "yes".  It is compiled with LIBGCC_SYNC_CFLAGS and provides
-   out-of-line versions of all relevant __sync_* primitives.
-
-   These routines are intended for targets like MIPS that have two
-   ISA encodings (the "normal" ISA and the MIPS16 ISA).  The normal
-   ISA provides full synchronization capabilities but the MIPS16 ISA
-   has no encoding for them.  MIPS16 code must therefore call external
-   non-MIPS16 implementations of the __sync_* routines.
-
-   The file is compiled once for each routine.  The following __foo
-   routines are selected by defining a macro called L<foo>:
-
-       __sync_synchronize
-
-   The following __foo_N routines are selected by defining FN=foo
-   and SIZE=N:
-
-       __sync_fetch_and_add_N
-       __sync_fetch_and_sub_N
-       __sync_fetch_and_or_N
-       __sync_fetch_and_and_N
-       __sync_fetch_and_xor_N
-       __sync_fetch_and_nand_N
-       __sync_add_and_fetch_N
-       __sync_sub_and_fetch_N
-       __sync_or_and_fetch_N
-       __sync_and_and_fetch_N
-       __sync_xor_and_fetch_N
-       __sync_nand_and_fetch_N
-       __sync_bool_compare_and_swap_N
-       __sync_val_compare_and_swap_N
-       __sync_lock_test_and_set_N
-
-   SIZE can be 1, 2, 4, 8 or 16.  __foo_N is omitted if the target does
-   not provide __sync_compare_and_swap_N.
-
-   Note that __sync_lock_release does not fall back on external
-   __sync_lock_release_N functions.  The default implementation
-   of __sync_lock_release is a call to __sync_synchronize followed
-   by a store of zero, so we don't need separate library functions
-   for it.  */
