-/* 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. */
