Enumeration Type Documentation

OpenACCExecMapping

enum mlir::acc::OpenACCExecMapping

Enumeration used to encode the execution mapping on a loop construct.

They refer directly to the OpenACC 3.3 standard: 2.9.2. gang 2.9.3. worker 2.9.4. vector

Value can be combined bitwise to reflect the mapping applied to the construct. e.g. acc.loop gang vector, the gang and vector could be combined and the final mapping value would be 5 (4 | 1).

Function Documentation

createLegalizeDataInRegion()

std::unique_ptr< OperationPass< func::FuncOp > > mlir::acc::createLegalizeDataInRegion

(

)

Create a pass to replace ssa values in region with device/host values.

Definition at line 89 of file LegalizeData.cpp.

getAccPtr()

mlir::Value mlir::acc::getAccPtr

(

mlir::Operation *

accDataClauseOp

)

Used to obtain the accPtr from a data clause operation.

When a data entry operation, it obtains its result accPtr value. If a data exit operation, it obtains its operand accPtr value. Returns empty value if not a data clause operation.

References ACC_DATA_ENTRY_OPS, and ACC_DATA_EXIT_OPS.

getAsyncOnly()

mlir::ArrayAttr mlir::acc::getAsyncOnly

(

mlir::Operation *

accDataClauseOp

)

Returns an array of acc:DeviceTypeAttr attributes attached to an acc data clause operation, that correspond to the device types associated with the async clauses without an async-value.

Definition at line 2931 of file OpenACC.cpp.

References ACC_DATA_ENTRY_OPS, and ACC_DATA_EXIT_OPS.

getAsyncOperands()

mlir::SmallVector< mlir::Value > mlir::acc::getAsyncOperands

(

mlir::Operation *

accDataClauseOp

)

Used to obtain async operands from an acc data clause operation.

Returns an empty vector if there are no such operands.

Definition at line 2909 of file OpenACC.cpp.

getAsyncOperandsDeviceType()

mlir::ArrayAttr mlir::acc::getAsyncOperandsDeviceType

(

mlir::Operation *

accDataClauseOp

)

Returns an array of acc:DeviceTypeAttr attributes attached to an acc data clause operation, that correspond to the device types associated with the async clauses with an async-value.

Definition at line 2923 of file OpenACC.cpp.

References ACC_DATA_ENTRY_OPS, and ACC_DATA_EXIT_OPS.

getBounds()

mlir::SmallVector< mlir::Value > mlir::acc::getBounds

(

mlir::Operation *
