+/* The defines below are used to instrument the vm code
+ * with different state changes. There are two variants
+ * of each define. One that has a cached ErtsMsAcc *
+ * that it can use, and one that does not.
+ * The cached values are necessary to have in order to get
+ * low enough overhead when running without msacc enabled.
+ *
+ * The two most common patterns to use the function with are:
+ *
+ * ERTS_MSACC_PUSH_AND_SET_STATE(ERTS_MSACC_STATE_NEWSTATE);
+ * ... call other function in new state ...
+ * ERTS_MSACC_POP_STATE();
+ *
+ * Note that the erts_msacc_push* function declare new variables, so
+ * to conform with C89 we have to call it in the beginning of a function.
+ * We might not want to change state it the beginning though, so we use this:
+ *
+ * ERTS_MSACC_PUSH_STATE();
+ * ... some other code ...
+ * ERTS_MSACC_SET_STATE_CACHED(ERTS_MSACC_STATE_NEWSTATE);
+ * ... call other function in new state ...
+ * ERTS_MSACC_POP_STATE();
+ *
+ * Notice that we used the cached version of set_state as push_state already
+ * read the erts_msacc_enabled to the cache.
+ *
+ * Most macros also have other variants with the suffix _m which means that
+ * they are known to only be called in managed threads, or with the _x suffix
+ * which means that it should only be used in an emulator compiled with
+ * extended states.
+ *
+ * Here is a listing of the entire api:
+ *
+ * void ERTS_MSACC_DECLARE_CACHE()
+ * void ERTS_MSACC_UPDATE_CACHE()
+ * void ERTS_MSACC_IS_ENABLED()
+ * void ERTS_MSACC_IS_ENABLED_CACHED()

+ * * Move ErtsTracerNif into ErtsTracer
+ * + Removes need for locking
+ * + Removes hash lookup overhead
+ * + Use a refc on the ErtsTracerNif to know when it can
+ * be freed. We don't want to allocate a separate
+ * ErtsTracerNif for each module used.
+ * * Optimize GenericBp for cache locality by reusing equivalent
+ * GenericBp and GenericBpData in multiple tracer points.
