Typedefs
template<typename OpTy>
using	mlir::acc::detail::has_device_type_clauses_t
	The constructs carrying a device_type clause hold their async and wait clauses per device type.
template<typename OpTy>
using	mlir::acc::detail::has_async_only_t = decltype(std::declval<OpTy>().getAsyncOnly())
template<typename OpTy>
using	mlir::acc::detail::has_wait_only_t = decltype(std::declval<OpTy>().getWaitOnly())

Functions
Location	mlir::acc::unfuseLoc (Location loc)
	Unfuses fused locations, returning the last sub-location.
std::optional< FileLineColLoc >	mlir::acc::getFileLineColLoc (Location loc, bool errorOnInvalidLocation)
	Returns file:line:column location information when available.
StringRef	mlir::acc::getParentFunctionName (Operation *op)
	Returns the symbol name of the function op belongs to, or of op itself when it is a function.
StringRef	mlir::acc::getParentFunctionName (Value value)
	Returns the enclosing function symbol name for value's defining op.
StringRef	mlir::acc::getParentFunctionName (ValueRange values)
	Returns the first non-empty enclosing function name from values.
std::string	mlir::acc::getInternalGlobalName (StringRef kind, StringRef detail)
	Returns the name to give a global that the conversion creates to hold detail of kind, such as the name of a variable or a source position.
Value	mlir::acc::getOrCreateGlobalString (Location loc, OpBuilder &builder, StringRef name, StringRef value, Region &globalSymbolRegion, SymbolTable *symbolTable=nullptr)
	Creates or reuses a null-terminated string global in globalSymbolRegion.
Value	mlir::acc::createIdent (Location loc, StringRef functionName, OpBuilder &builder, Region &globalSymbolRegion, const ACCRuntimeCallConfig &config, SymbolTable *symbolTable=nullptr)
	Returns a pointer to a constant global holding an ident_t for OpenACC runtime calls.
Value	mlir::acc::castToI64 (Location loc, Value value, OpBuilder &builder)
	Sign-extends or truncates value to the i64 the runtime entry points take for values like queue numbers.
Value	mlir::acc::getAsyncQueue (Location loc, Value asyncOperand, bool asyncOnly, OpBuilder &builder, const ACCRuntimeCallConfig &config)
	Returns the queue an async clause selects: the value of the clause when it has one, the queue standing for an async clause without a value when asyncOnly is set, and the synchronous queue when there is no clause at all.
LogicalResult	mlir::acc::emitWaitCall (Location loc, ValueRange waitOperands, Value asyncQueue, OpBuilder &builder, Region &globalSymbolRegion, SymbolTable &symbolTable, const ACCRuntimeCallConfig &config, Value deviceNum={})
	Emits the runtime call that waits for waitOperands on asyncQueue, which is what a wait clause or an acc.wait directive asks for.
FailureOr< Value >	mlir::acc::emitGetDevicePtrCall (Operation *clauseOp, Value hostPtr, bool ifPresent, OpBuilder &builder, Region &globalSymbolRegion, SymbolTable &symbolTable, const ACCRuntimeCallConfig &config)
	Emits the runtime call that asks for the device address the object of the data clause clauseOp is mapped to, which is what a use_device clause exposes in the body of its construct.
LogicalResult	mlir::acc::emitGuardedByIfCond (Location loc, Value ifCond, RewriterBase &rewriter, function_ref< LogicalResult()> emitFn)
	Runs emitFn guarded by a branch on ifCond, or unguarded when there is no condition.
FailureOr< Value >	mlir::acc::emitValueSelectedByIfCond (Location loc, Value ifCond, RewriterBase &rewriter, function_ref< FailureOr< Value >()> thenFn, function_ref< FailureOr< Value >()> elseFn)
	Emits thenFn on the path a branch on ifCond takes and elseFn on the other one, and returns the value that reaches the code following the branch.
void	mlir::acc::spliceConstructRegion (Operation *op, Region &region, RewriterBase &rewriter)
	Splices region, the body of a structured construct, into the block holding op, so that the construct itself can be erased.
SmallVector< DeviceType, 3 >	mlir::acc::getDeviceTypesByPrecedence (DeviceType deviceType)
	The clauses of a construct can be given once per device type.
template<typename OpTy>
Value	mlir::acc::getAsyncClauseValue (OpTy op, DeviceType deviceType, bool &asyncOnly)
	Returns the value the async clause of op names for deviceType, and sets asyncOnly when the clause names no queue.
template<typename OpTy>
std::optional< DeviceType >	mlir::acc::getWaitClauseValues (OpTy op, DeviceType deviceType, SmallVectorImpl< Value > &waitValues)
	Appends to waitValues the queues the wait clause of op names for deviceType, and returns the device type the clause naming them is given for - a clause naming no queue waits for every one of them.
template<typename OpTy>
bool	mlir::acc::hasWaitDevnum (OpTy op, DeviceType deviceType)
	Returns whether the wait clause op gives for deviceType carries a devnum modifier, which selects the device the queues belong to.
template<typename OpTy>
Value	mlir::acc::getAsyncQueue (OpTy op, DeviceType deviceType, ConversionPatternRewriter &rewriter, const ACCRuntimeCallConfig &config)
	Returns the queue that the runtime calls of op run on, from the async clause it gives for deviceType.
template<typename OpTy>
LogicalResult	mlir::acc::emitWaitClause (OpTy op, DeviceType deviceType, Value asyncQueue, ConversionPatternRewriter &rewriter, OpenACCSupport &accSupport, Region &globalSymbolRegion, SymbolTable &symbolTable, const ACCRuntimeCallConfig &config)
	Emits the wait that a wait clause on op asks for before the runtime calls of the construct, waiting on asyncQueue for the queues the clause names, or for every queue when it names none.
