Roughly, transactions provide +synchronization guarantees that are similar to what would be guaranteed when +using a single global lock as a guard for all transactions. Note that like +other synchronization constructs in C/C++, transactions rely on a +data-race-free program (e.g., a nontransactional write that is concurrent +with a transactional read to the same memory location is a data race). + +@c --------------------------------------------------------------------- +@c The libitm ABI +@c --------------------------------------------------------------------- + +@node The libitm ABI +@chapter The libitm ABI + +The ABI provided by libitm is basically equal to the Linux variant of Intel's +current TM ABI specification document (Revision 1.1, May 6 2009) but with the +differences listed in this chapter. It would be good if these changes would +eventually be merged into a future version of this specification. To ease +look-up, the following subsections mirror the structure of this specification. + +@section [No changes] Objectives +@section [No changes] Non-objectives + +@section Library design principles +@subsection [No changes] Calling conventions +@subsection [No changes] TM library algorithms +@subsection [No changes] Optimized load and store routines +@subsection [No changes] Aligned load and store routines + +@subsection Data logging functions + +The memory locations accessed with transactional loads and stores and the +memory locations whose values are logged must not overlap. This required +separation only extends to the scope of the execution of one transaction +including all the executions of all nested transactions. + +The compiler must be consistent (within the scope of a single transaction) +about which memory locations are shared and which are not shared with other +threads (i.e., data must be accessed either transactionally or +nontransactionally). Otherwise, non-write-through TM algorithms would not work. + +For memory locations on the stack, this requirement extends to only the +lifetime of the stack frame that the memory location belongs to (or the +lifetime of the transaction, whichever is shorter). Thus, memory that is +reused for several stack frames could be target of both data logging and +transactional accesses; however, this is harmless because these stack frames' +lifetimes will end before the transaction finishes. + +@subsection [No changes] Scatter/gather calls +@subsection [No changes] Serial and irrevocable mode +@subsection [No changes] Transaction descriptor +@subsection Store allocation + +There is no @code{getTransaction} function. + +@subsection [No changes] Naming conventions + +@subsection Function pointer encryption + +Currently, this is not implemented. + + +@section Types and macros list + +@code{_ITM_codeProperties} has changed, @pxref{txn-code-properties,,Starting a +transaction}. +@code{_ITM_srcLocation} is not used. + + +@section Function list + +@subsection Initialization and finalization functions +These functions are not part of the ABI. + +@subsection [No changes] Version checking +@subsection [No changes] Error reporting +@subsection [No changes] inTransaction call + +@subsection State manipulation functions +There is no @code{getTransaction} function.

The Intel ABI requires the +@code{_ITM_tryCommitTransaction} function that will return even when the +commit failed and will have to be matched with calls to either +@code{_ITM_abortTransaction} or @code{_ITM_commitTransaction}. In contrast, +gcc relies on transactional wrappers for the functions of the Exception +Handling ABI and on one additional commit function (shown below). This allows +the TM to keep track of EH internally and thus it does not have to embed the +cleanup of EH state into the existing EH code in the program. +@code{_ITM_tryCommitTransaction} is not supported. +@code{_ITM_commitTransactionToId} is also not supported because the +propagation of thrown exceptions will not bypass commits of nested +transactions. + +@example +void _ITM_commitTransactionEH(void *exc_ptr) ITM_REGPARM; +void *_ITM_cxa_allocate_exception (size_t); +void _ITM_cxa_throw (void *obj, void *tinfo, void *dest); +void *_ITM_cxa_begin_catch (void *exc_ptr); +void _ITM_cxa_end_catch (void); +@end example + +@code{_ITM_commitTransactionEH} must be called to commit a transaction if an +exception could be in flight at this position in the code. @code{exc_ptr} is +the current exception or zero if there is no current exception. +The @code{_ITM_cxa...} functions are transactional wrappers for the respective +@code{__cxa...} functions and must be called instead of these in transactional +code. + +To support this EH scheme, libstdc++ needs to provide one additional function +(@code{_cxa_tm_cleanup}), which is used by the TM to clean up the exception +handling state while rolling back a transaction: + +@example +void __cxa_tm_cleanup (void *unthrown_obj, void *cleanup_exc, + unsigned int caught_count); +@end example + +@code{unthrown_obj} is non-null if the program called +@code{__cxa_allocate_exception} for this exception but did not yet called +@code{__cxa_throw} for it. @code{cleanup_exc} is non-null if the program is +currently processing a cleanup along an exception path but has not caught this +exception yet. @code{caught_count} is the nesting depth of +@code{__cxa_begin_catch} within the transaction (which can be counted by the TM +using @code{_ITM_cxa_begin_catch} and @code{_ITM_cxa_end_catch}); +@code{__cxa_tm_cleanup} then performs rollback by essentially performing +@code{__cxa_end_catch} that many times. + + + +@subsection Exception handling support + +Currently, there is no support for functionality like +@code{__transaction_cancel throw} as described in the C++ TM specification. +Supporting this should be possible with the EH scheme explained previously +because via the transactional wrappers for the EH ABI, the TM is able to +observe and intercept EH. + + +@subsection [No changes] Transition to serial--irrevocable mode +@subsection [No changes] Data transfer functions +@subsection [No changes] Transactional memory copies + +@subsection Transactional versions of memmove + +If either the source or destination memory region is to be accessed +nontransactionally, then source and destination regions must not be +overlapping. The respective @code{_ITM_memmove} functions are still +available but a fatal runtime error will be raised if such regions do overlap. +To support this functionality, the ABI would have to specify how the +intersection of the regions has to be accessed (i.e., transactionally or +nontransactionally). + +@subsection [No changes] Transactional versions of memset +@subsection [No changes] Logging functions + +@subsection User-registered commit and undo actions + +Commit actions will get executed in the same order in which the respective +calls to @code{_ITM_addUserCommitAction} happened.

Commit actions get executed after +privatization safety has been ensured. + +Undo actions will get executed in reverse order compared to the order in which +the respective calls to @code{_ITM_addUserUndoAction} happened. The ordering of +undo actions w.r.t. the roll-back of other actions (e.g., data transfers or +memory allocations) is undefined. + +@code{_ITM_getThreadnum} is not supported currently because its only purpose +is to provide a thread ID that matches some assumed performance tuning output, +but this output is not part of the ABI nor further defined by it. + +@code{_ITM_dropReferences} is not supported currently because its semantics and +the intention behind it is not entirely clear. The +specification suggests that this function is necessary because of certain +orderings of data transfer undos and the releasing of memory regions (i.e., +privatization). However, this ordering is never defined, nor is the ordering of +dropping references w.r.t. other events. + +@subsection [New] Transactional indirect calls + +Indirect calls (i.e., calls through a function pointer) within transactions +should execute the transactional clone of the original function (i.e., a clone +of the original that has been fully instrumented to use the TM runtime), if +such a clone is available. The runtime provides two functions to +register/deregister clone tables: + +@example +struct clone_entry +@{ + void *orig, *clone; +@}; + +void _ITM_registerTMCloneTable (clone_entry *table, size_t entries); +void _ITM_deregisterTMCloneTable (clone_entry *table); +@end example + +Registered tables must be writable by the TM runtime, and must be live +throughout the life-time of the TM runtime. + +@strong{TODO} The intention was always to drop the registration functions +entirely, and create a new ELF Phdr describing the linker-sorted table. Much +like what currently happens for @code{PT_GNU_EH_FRAME}. +This work kept getting bogged down in how to represent the @var{N} different +code generation variants. We clearly needed at least two---SW and HW +transactional clones---but there was always a suggestion of more variants for +different TM assumptions/invariants. + +The compiler can then use two TM runtime functions to perform indirect calls in +transactions: +@example +void *_ITM_getTMCloneOrIrrevocable (void *function) ITM_REGPARM; +void *_ITM_getTMCloneSafe (void *function) ITM_REGPARM; +@end example + +If there is a registered clone for supplied function, both will return a +pointer to the clone. If not, the first runtime function will attempt to switch +to serial--irrevocable mode and return the original pointer, whereas the second +will raise a fatal runtime error. + +@subsection [New] Transactional dynamic memory management + +@example +void *_ITM_malloc (size_t) + __attribute__((__malloc__)) ITM_PURE; +void *_ITM_calloc (size_t, size_t) + __attribute__((__malloc__)) ITM_PURE; +void _ITM_free (void *) ITM_PURE; +@end example + +These functions are essentially transactional wrappers for @code{malloc}, +@code{calloc}, and @code{free}. Within transactions, the compiler should +replace calls to the original functions with calls to the wrapper functions. + + +@section [No changes] Future Enhancements to the ABI + +@section Sample code + +The code examples might not be correct w.r.t. the current version of the ABI, +especially everything related to exception handling. + + +@section [New] Memory model + +The ABI should define a memory model and the ordering that is guaranteed for +data transfers and commit/undo actions, or at least refer to another memory +model that needs to be preserved. Without that, the compiler cannot ensure the +memory model specified on the level of the programming language (e.g., by the +C++ TM specification). + +For example, if a transactional load is ordered before another load/store, then +the TM runtime must also ensure this ordering when accessing shared state. If +not, this might break the kind of publication safety used in the C++ TM +specification. Likewise, the TM runtime must ensure privatization safety. + + + +@c --------------------------------------------------------------------- +@c Internals +@c --------------------------------------------------------------------- + +@node Internals +@chapter Internals + +@section TM methods and method groups + +libitm supports several ways of synchronizing transactions with each other. +These TM methods (or TM algorithms) are implemented in the form of +subclasses of @code{abi_dispatch}, which provide methods for +transactional loads and stores as well as callbacks for rollback and commit. +All methods that are compatible with each other (i.e., that let concurrently +running transactions still synchronize correctly even if different methods +are used) belong to the same TM method group. Pointers to TM methods can be +obtained using the factory methods prefixed with @code{dispatch_} in +@file{libitm_i.h}. There are two special methods, @code{dispatch_serial} and +@code{dispatch_serialirr}, that are compatible with all methods because they +run transactions completely in serial mode. + +@subsection TM method life cycle + +The state of TM methods does not change after construction, but they do alter +the state of transactions that use this method. However, because +per-transaction data gets used by several methods, @code{gtm_thread} is +responsible for setting an initial state that is useful for all methods. +After that, methods are responsible for resetting/clearing this state on each +rollback or commit (of outermost transactions), so that the transaction +executed next is not affected by the previous transaction. + +There is also global state associated with each method group, which is +initialized and shut down (@code{method_group::init()} and @code{fini()}) +when switching between method groups (see @file{retry.cc}). + +@subsection Selecting the default method + +The default method that libitm uses for freshly started transactions (but +not necessarily for restarted transactions) can be set via an environment +variable (@env{ITM_DEFAULT_METHOD}), whose value should be equal to the name +of one of the factory methods returning abi_dispatch subclasses but without +the "dispatch_" prefix (e.g., "serialirr" instead of +@code{GTM::dispatch_serialirr()}). + +Note that this environment variable is only a hint for libitm and might not +be supported in the future. + + +@section Nesting: flat vs. closed + +We support two different kinds of nesting of transactions. In the case of +@emph{flat nesting}, the nesting structure is flattened and all nested +transactions are subsumed by the enclosing transaction. In contrast, +with @emph{closed nesting}, nested transactions that have not yet committed +can be rolled back separately from the enclosing transactions; when they +commit, they are subsumed by the enclosing transaction, and their effects +will be finally committed when the outermost transaction commits. +@emph{Open nesting} (where nested transactions can commit independently of the +enclosing transactions) are not supported. + +Flat nesting is the default nesting mode, but closed nesting is supported and +used when transactions contain user-controlled aborts +(@code{__transaction_cancel} statements). We assume that user-controlled +aborts are rare in typical code and used mostly in exceptional situations. +Thus, it makes more sense to use flat nesting by default to avoid the +performance overhead of the additional checkpoints required for closed +nesting. User-controlled aborts will correctly abort the innermost enclosing +transaction, whereas the whole (i.e., outermost) transaction will be restarted +otherwise (e.g., when a transaction encounters data conflicts during +optimistic execution). + + +@section Locking conventions + +This section documents the locking scheme and rules for all uses of locking +in libitm. We have to support serial(-irrevocable) mode, which is implemented +using a global lock as explained next (called the @emph{serial lock}). To +simplify the overall design, we use the same lock as catch-all locking +mechanism for other infrequent tasks such as (de)registering clone tables or +threads. Besides the serial lock, there are @emph{per-method-group locks} that +are managed by specific method groups (i.e., groups of similar TM concurrency +control algorithms), and lock-like constructs for quiescence-based operations +such as ensuring privatization safety. + +Thus, the actions that participate in the libitm-internal locking are either +@emph{active transactions} that do not run in serial mode, @emph{serial +transactions} (which (are about to) run in serial mode), and management tasks +that do not execute within a transaction but have acquired the serial mode +like a serial transaction would do (e.g., to be able to register threads with +libitm). Transactions become active as soon as they have successfully used the +serial lock to announce this globally (@pxref{serial-lock-impl,,Serial lock +implementation}). Likewise, transactions become serial transactions as soon as +they have acquired the exclusive rights provided by the serial lock (i.e., +serial mode, which also means that there are no other concurrent active or +serial transactions). Note that active transactions can become serial +transactions when they enter serial mode during the runtime of the +transaction. + +@subsection State-to-lock mapping + +Application data is protected by the serial lock if there is a serial +transaction and no concurrently running active transaction (i.e., non-serial). +Otherwise, application data is protected by the currently selected method +group, which might use per-method-group locks or other mechanisms. Also note +that application data that is about to be privatized might not be allowed to be +accessed by nontransactional code until privatization safety has been ensured; +the details of this are handled by the current method group. + +libitm-internal state is either protected by the serial lock or accessed +through custom concurrent code. The latter applies to the public/shared part +of a transaction object and most typical method-group-specific state. + +The former category (protected by the serial lock) includes: +@itemize @bullet +@item The list of active threads that have used transactions. +@item The tables that map functions to their transactional clones. +@item The current selection of which method group to use. +@item Some method-group-specific data, or invariants of this data. For example, +resetting a method group to its initial state is handled by switching to the +same method group, so the serial lock protects such resetting as well. +@end itemize +In general, such state is immutable whenever there exists an active +(non-serial) transaction. If there is no active transaction, a serial +transaction (or a thread that is not currently executing a transaction but has +acquired the serial lock) is allowed to modify this state (but must of course +be careful to not surprise the current method group's implementation with such +modifications). + +@subsection Lock acquisition order + +To prevent deadlocks, locks acquisition must happen in a globally agreed-upon +order. Note that this applies to other forms of blocking too, but does not +necessarily apply to lock acquisitions that do not block (e.g., trylock() +calls that do not get retried forever). Note that serial transactions are +never return back to active transactions until the transaction has committed. +Likewise, active transactions stay active until they have committed. +Per-method-group locks are typically also not released before commit. + +Lock acquisition / blocking rules: +@itemize @bullet + +@item Transactions must become active or serial before they are allowed to +use method-group-specific locks or blocking (i.e., the serial lock must be +acquired before those other locks, either in serial or nonserial mode). + +@item Any number of threads that do not currently run active transactions can +block while trying to get the serial lock in exclusive mode. Note that active +transactions must not block when trying to upgrade to serial mode unless there +is no other transaction that is trying that (the latter is ensured by the +serial lock implementation. + +@item Method groups must prevent deadlocks on their locks. In particular, they +must also be prepared for another active transaction that has acquired +method-group-specific locks but is blocked during an attempt to upgrade to +being a serial transaction. See below for details. + +@item Serial transactions can acquire method-group-specific locks because there +will be no other active nor serial transaction. + +@end itemize + +There is no single rule for per-method-group blocking because this depends on +when a TM method might acquire locks. If no active transaction can upgrade to +being a serial transaction after it has acquired per-method-group locks (e.g., +when those locks are only acquired during an attempt to commit), then the TM +method does not need to consider a potential deadlock due to serial mode. + +If there can be upgrades to serial mode after the acquisition of +per-method-group locks, then TM methods need to avoid those deadlocks: +@itemize @bullet +@item When upgrading to a serial transaction, after acquiring exclusive rights +to the serial lock but before waiting for concurrent active transactions to +finish (@pxref{serial-lock-impl,,Serial lock implementation} for details), +we have to wake up all active transactions waiting on the upgrader's +per-method-group locks. +@item Active transactions blocking on per-method-group locks need to check the +serial lock and abort if there is a pending serial transaction. +@item Lost wake-ups have to be prevented (e.g., by changing a bit in each +per-method-group lock before doing the wake-up, and only blocking on this lock +using a futex if this bit is not group). +@end itemize + +@strong{TODO}: Can reuse serial lock for gl-*? And if we can, does it make +sense to introduce further complexity in the serial lock? For gl-*, we can +really only avoid an abort if we do -wb and -vbv. + + +@subsection Serial lock implementation +@anchor{serial-lock-impl} + +The serial lock implementation is optimized towards assuming that serial +transactions are infrequent and not the common case. However, the performance +of entering serial mode can matter because when only few transactions are run +concurrently or if there are few threads, then it can be efficient to run +transactions serially. + +The serial lock is similar to a multi-reader-single-writer lock in that there +can be several active transactions but only one serial transaction. However, +we do want to avoid contention (in the lock implementation) between active +transactions, so we split up the reader side of the lock into per-transaction +flags that are true iff the transaction is active. The exclusive writer side +remains a shared single flag, which is acquired using a CAS, for example. +On the fast-path, the serial lock then works similar to Dekker's algorithm but +with several reader flags that a serial transaction would have to check. +A serial transaction thus requires a list of all threads with potentially +active transactions; we can use the serial lock itself to protect this list +(i.e., only threads that have acquired the serial lock can modify this list). + +We want starvation-freedom for the serial lock to allow for using it to ensure +progress for potentially starved transactions (@pxref{progress-guarantees,, +Progress Guarantees} for details). However, this is currently not enforced by +the implementation of the serial lock. + +Here is pseudo-code for the read/write fast paths of acquiring the serial +lock (read-to-write upgrade is similar to write_lock: +@example +// read_lock: +tx->shared_state |= active; +__sync_synchronize(); // or STLD membar, or C++0x seq-cst fence +while (!serial_lock.exclusive) + if (spinning_for_too_long) goto slowpath; + +// write_lock: +if (CAS(&serial_lock.exclusive, 0, this) != 0) + goto slowpath; // writer-writer contention +// need a membar here, but CAS already has full membar semantics +bool need_blocking = false; +for (t: all txns) + @{ + for (;t->shared_state & active;) + if (spinning_for_too_long) @{ need_blocking = true; break; @} + @} +if (need_blocking) goto slowpath; +@end example + +Releasing a lock in this spin-lock version then just consists of resetting +@code{tx->shared_state} to inactive or clearing @code{serial_lock.exclusive}. + +However, we can't rely on a pure spinlock because we need to get the OS +involved at some time (e.g., when there are more threads than CPUs to run on). +Therefore, the real implementation falls back to a blocking slow path, either +based on pthread mutexes or Linux futexes. + + +@subsection Reentrancy + +libitm has to consider the following cases of reentrancy: +@itemize @bullet + +@item Transaction calls unsafe code that starts a new transaction: The outer +transaction will become a serial transaction before executing unsafe code. +Therefore, nesting within serial transactions must work, even if the nested +transaction is called from within uninstrumented code. + +@item Transaction calls either a transactional wrapper or safe code, which in +turn starts a new transaction: It is not yet defined in the specification +whether this is allowed. Thus, it is undefined whether libitm supports this. + +@item Code that starts new transactions might be called from within any part +of libitm: This kind of reentrancy would likely be rather complex and can +probably be avoided. Therefore, it is not supported. + +@end itemize + +@subsection Privatization safety + +Privatization safety is ensured by libitm using a quiescence-based approach. +Basically, a privatizing transaction waits until all concurrent active +transactions will either have finished (are not active anymore) or operate on +a sufficiently recent snapshot to not access the privatized data anymore. This +happens after the privatizing transaction has stopped being an active +transaction, so waiting for quiescence does not contribute to deadlocks. + +In method groups that need to ensure publication safety explicitly, active +transactions maintain a flag or timestamp in the public/shared part of the +transaction descriptor. Before blocking, privatizers need to let the other +transactions know that they should wake up the privatizer. + +@strong{TODO} Ho to implement the waiters? Should those flags be +per-transaction or at a central place? We want to avoid one wake/wait call +per active transactions, so we might want to use either a tree or combining +to reduce the syscall overhead, or rather spin for a long amount of time +instead of doing blocking. Also, it would be good if only the last transaction +that the privatizer waits for would do the wake-up. + +@subsection Progress guarantees +@anchor{progress-guarantees} + +Transactions that do not make progress when using the current TM method will +eventually try to execute in serial mode. Thus, the serial lock's progress +guarantees determine the progress guarantees of the whole TM. Obviously, we at +least need deadlock-freedom for the serial lock, but it would also be good to +provide starvation-freedom (informally, all threads will finish executing a +transaction eventually iff they get enough cycles). + +However, the scheduling of transactions (e.g., thread scheduling by the OS) +also affects the handling of progress guarantees by the TM. First, the TM +can only guarantee deadlock-freedom if threads do not get stopped. Likewise, +low-priority threads can starve if they do not get scheduled when other +high-priority threads get those cycles instead. + +If all threads get scheduled eventually, correct lock implementations will +provide deadlock-freedom, but might not provide starvation-freedom. We can +either enforce the latter in the TM's lock implementation, or assume that +the scheduling is sufficiently random to yield a probabilistic guarantee that +no thread will starve (because eventually, a transaction will encounter a +scheduling that will allow it to run). This can indeed work well in practice +but is not necessarily guaranteed to work (e.g., simple spin locks can be +pretty efficient). + +Because enforcing stronger progress guarantees in the TM has a higher runtime +overhead, we focus on deadlock-freedom right now and assume that the threads +will get scheduled eventually by the OS (but don't consider threads with +different priorities). We should support starvation-freedom for serial +transactions in the future. Everything beyond that is highly related to proper +contention management across all of the TM (including with TM method to +choose), and is future work. + +@strong{TODO} Handling thread priorities: We want to avoid priority inversion +but it's unclear how often that actually matters in practice. Workloads that +have threads with different priorities will likely also require lower latency +or higher throughput for high-priority threads. Therefore, it probably makes +not that much sense (except for eventual progress guarantees) to use +priority inheritance until the TM has priority-aware contention management. + + +@c --------------------------------------------------------------------- +@c GNU Free Documentation License +@c --------------------------------------------------------------------- + +@include fdl.texi + +@c --------------------------------------------------------------------- +@c Index +@c --------------------------------------------------------------------- + +@node Index +@unnumbered Index + +@printindex cp + +@bye diff --git a/gcc-4.9/libitm/libitm_i.h b/gcc-4.9/libitm/libitm_i.h new file mode 100644 index 000000000..7c24493e3 --- /dev/null +++ b/gcc-4.9/libitm/libitm_i.h @@ -0,0 +1,351 @@ +/* Copyright (C) 2008-2014 Free Software Foundation, Inc. + Contributed by Richard Henderson <rth@redhat.com>. + + This file is part of the GNU Transactional Memory Library (libitm). + + Libitm is free software; you can redistribute it and/or modify it + under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + Libitm is distributed in the hope that it will be useful, but WITHOUT ANY + WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS + FOR A PARTICULAR PURPOSE.
