/* A fuzz test for CPython.
The only exposed function is LLVMFuzzerTestOneInput, which is called by
fuzzers and by the _fuzz module for smoke tests.
To build exactly one fuzz test, as when running in oss-fuzz etc.,
build with -D _Py_FUZZ_ONE and -D _Py_FUZZ_<test_name>. e.g. to build
LLVMFuzzerTestOneInput to only run "fuzz_builtin_float", build this file with
-D _Py_FUZZ_ONE -D _Py_FUZZ_fuzz_builtin_float.
See the source code for LLVMFuzzerTestOneInput for details. */
