Commit Message

Mark Rutland June 21, 2018, 12:13 p.m. UTC
Some of the atomics return the result of a test applied after the atomic
operation, and almost all architectures implement these as trivial
wrappers around the underlying atomic. Specifically:

* <atomic>_inc_and_test(v) is (<atomic>_inc_return(v) == 0)

* <atomic>_dec_and_test(v) is (<atomic>_dec_return(v) == 0)

* <atomic>_sub_and_test(i, v) is (<atomic>_sub_return(i, v) == 0)

* <atomic>_add_negative(i, v) is (<atomic>_add_return(i, v) < 0)

Rather than have these definitions duplicated in all architectures, with
minor inconsistencies in formatting and documentation, let's make these
operations optional, with default fallbacks as above. Implementations
must now provide a preprocessor symbol.

The instrumented atomics are updated accordingly.

Both x86 and m68k have custom implementations, which are left as-is,
given preprocessor symbols to avoid being overridden.

There should be no functional change as a result of this patch.
