class PredicateBranch

Declaration

class PredicateBranch : public PredicateWithEdge { /* full declaration omitted */ };

Description

An intrusive list node. A base class to enable membership in intrusive lists, including \a simple_ilist, \a iplist, and \a ilist. The first template parameter is the\a value_type for the list. An ilist node can be configured with compile-time options to change behaviour and/or add API. By default, an \a ilist_node knows whether it is the list sentinel (an instance of \a ilist_sentinel) if and only if LLVM_ENABLE_ABI_BREAKING_CHECKS. The function \a isKnownSentinel() always returns \c false tracking is off. Sentinel tracking steals a bit from the "prev" link, which adds a mask operation when decrementing an iterator, but enables bug-finding assertions in \a ilist_iterator. To turn sentinel tracking on all the time, pass in the ilist_sentinel_tracking <true > template parameter. This also enables the \a isSentinel() function. The same option must be passed to the intrusive list. (ilist_sentinel_tracking <false > turns sentinel tracking off all the time.) A type can inherit from ilist_node multiple times by passing in different\a ilist_tag options. This allows a single instance to be inserted into multiple lists simultaneously, where each list is given the same tag. struct A {}; struct B {}; struct N : ilist_node <N , ilist_tag <A >>, ilist_node <N , ilist_tag <B >> {}; void foo() { simple_ilist <N , ilist_tag <A >> ListA; simple_ilist <N , ilist_tag <B >> ListB; N N1; ListA.push_back(N1); ListB.push_back(N1); }\endexample See \a is_valid_option for steps on adding a new option.
