Acc

acc

The OpenACC (acc) dialect that models the OpenACC programming model in MLIR.

OpenACC is a directive-based programming model for accelerating applications on heterogeneous systems. This dialect exposes compute constructs, data constructs, loops, and the associated clauses so that host and accelerator code can be represented, analysed, and lowered to target-specific runtimes.

See external documentation.

VarNameAttr

Bases: ParametrizedAttribute

Variable-name metadata attribute (upstream #acc.var_name<"x">).

Upstream attaches this purely as a discardable attribute on non-acc-dialect ops (e.g. memref.alloca, casts) to preserve source-level variable names through transformations. It is not an op argument on any acc op — the name slot on the data-clause family is OptionalAttr<StrAttr>:$name upstream, so xDSL keeps the plain StringAttr there too.

SpecializedRoutineAttr

Bases: ParametrizedAttribute

Marks a function as a device-specialized variant of an acc.routine (upstream #acc.specialized_routine<@routine, <par_level>, "name">).

Upstream attaches this as a discardable attribute on the specialized func.func produced by the routine-specialization pass. It captures the parallelism level, a SymbolRefAttr reference back to the originating acc.routine, and the original (pre-rename) function name. The par_level parameter prints inline as <gang_dim1> (no #acc.par_level prefix) to match upstream's spelling.

DeclareAttr

Bases: ParametrizedAttribute

Records that a variable is captured by an acc declare directive (upstream #acc.declare<dataClause = <clause>[, implicit = true]>).

Upstream attaches this as a discardable attribute to the variable's creation site — typically a global op (memref.global, llvm.mlir.global, …) or its allocation site — to advertise which user-level declare clause produced the capture. It pairs with acc.declare_enter / acc.declare_exit ops, which describe how the data action runs at runtime; the attribute itself just preserves the source-level clause kind so analyses can find the variable.

Parameters mirror upstream: a required DataClauseAttr and a defaulted implicit flag (false unless an OpenACC routine / standalone-declare lowering produced the capture implicitly). When implicit is false the print form omits it, matching upstream's DefaultValuedParameter<"bool", "false"> behaviour.

DeclareActionAttr dataclass

Bases: ParametrizedAttribute

Per-variable pre/post (de)allocation hook bundle for the OpenACC declare lowering (upstream #acc.declare_action<preAlloc = @sym, postAlloc = @sym, ...>).

Upstream attaches this as a discardable attribute to the variable's allocation site so the declare-directive lowering pass can find the runtime helpers it must invoke around the allocation. Each of the four slots is independently optional: a slot is absent if the corresponding hook does not exist for this variable. Absence is modelled with NoneAttr (xDSL has no OptionalParameter analogue for ParametrizedAttribute), and the printer omits absent slots so the on-the-wire form matches upstream's struct(params) spelling (<> when every slot is absent).

WaitClause dataclass

Bases: CustomDirective

Port of upstream custom<WaitClause>.

Follows a bare wait keyword in the format. The directive owns the optional surrounding parentheses. Syntax options after the keyword: bare → keyword-only = [#none] ( [ dts ] , group (, group) ) → kw-only + operand groups ( group (, group) ) → operand groups only where each group is { (devnum:)? %v : type, ... } ([dt])?.

The post-keyword body parse/print is shared via :func:_parse_wait_body / :func:_print_wait_body so other oilist-style directives can reuse the same spelling.

DataEntryOilist dataclass

Bases: CustomDirective

Port of upstream's oilist(...) for the data-entry op family.

Accepts the four optional clauses varPtrPtr / bounds / async / recipe in any order on parse; emits them in the canonical upstream-td-definition order on print. Each clause may appear at most once. This mirrors upstream MLIR's oilist(...) semantics — the round-trip with mlir-opt (which emits in upstream's td order) round-trips bit-identically through xDSL even when the input source interleaves clauses in a different order.

LoopControl dataclass

Bases: CustomDirective

Port of upstream custom<LoopControl>.

Owns acc.loop's region and the optional control(...) = (...) to (...) step (...) header. Syntax: control ( arg : T (, arg : T) ) = ( lb (, lb) : T (, T) ) to ( ub (, ub) : T (, T) ) step ( st (, st) : T (, T)* ) region | region

The first form provides induction variables to the region's entry block (matching upstream's parseRegion(region, inductionVars)); the second form is the container-like loop, which has no induction variables.

BindName dataclass

Bases: CustomDirective

Port of upstream custom<BindName>($bindIdName, $bindStrName, $bindIdNameDeviceType, $bindStrNameDeviceType).

Body of acc.routine's bind(...) clause. Each entry is either a SymbolRefAttr (@name) or a StringAttr ("name") optionally followed by [#acc.device_type<...>]. SymbolRef entries land in bindIdName (paired with bindIdNameDeviceType); String entries land in bindStrName (paired with bindStrNameDeviceType). On print, all id-name entries are emitted first, then all str-name entries — mirroring upstream's two-pass print.

RoutineGangClause dataclass

Bases: CustomDirective

Port of upstream custom<RoutineGangClause>($gang, $gangDim, $gangDimDeviceType).

Follows a bare gang keyword in acc.routine's format. The directive owns the optional surrounding parentheses. Syntax options after the keyword: bare → gang = [#none] ( [ dts ] ) → keyword-only DT list ( dim : ([dt])? (, ...)* ) → dim entries ( [ dts ] , dim : ([dt])? ) → mix of both dim: parses an attribute (typically 1 : i64), not an SSA operand.

DeviceTypeArrayClause dataclass

Bases: CustomDirective

Port of upstream custom<DeviceTypeArrayAttr>($deviceTypes).

Follows a bare keyword (e.g. worker) in acc.routine's format. The directive owns the optional surrounding parentheses. Syntax options after the keyword: bare → device_types = [#none] ( [ dts ] ) → list of device types Upstream's printer elides both the bare-#none form and any empty list, so an empty array round-trips as the bare keyword.

KernelEnvironmentOp

Bases: IRDLOperation

Implementation of upstream acc.kernel_environment — a decomposition of an OpenACC compute construct that captures only the data-mapping and asynchronous-behavior clauses (data / async / wait), leaving kernel execution parallelism and privatization to be handled separately. The body is a single block with no terminator and typically wraps a gpu.launch. See external documentation.

LoopOp

Bases: IRDLOperation

Implementation of upstream acc.loop — the OpenACC loop construct. See external documentation.

Carries the loop's induction variables (lowerbound / upperbound / step) plus per-device-type clauses for gang / worker / vector, private / firstprivate / reduction data ops, tile / cache operands, collapse group sizes, and seq / independent / auto parallelism mode markers. The body is an arbitrary region terminated by acc.yield.

The container-like loop count check from upstream's verifier (which uses LoopLikeOpInterface to enumerate loop ops) is intentionally skipped here — xDSL has no equivalent interface yet, so PR 17 of the OpenACC roadmap will wire it up alongside the other interface-driven traits.

UpdateOp

Bases: IRDLOperation

Implementation of upstream acc.update — the OpenACC update executable directive. See external documentation.

Unlike acc.enter_data / acc.exit_data, acc.update carries the same per-device-type async/wait operand+attribute shape as acc.parallel (variadic asyncOperands/waitOperands paired with *DeviceType, *Segments, hasWaitDevnum, and *Only arrays). It additionally carries an ifPresent UnitAttr but no async / wait keyword-only UnitAttrs (those are encoded via the *Only device-type arrays).

RoutineOp

Bases: IRDLOperation

Implementation of upstream acc.routine — captures the clauses of an OpenACC routine directive together with the associated function name. The function keeps track of its corresponding routine declaration via the acc.routine_info discardable attribute (an ArrayAttr of SymbolRefAttr pointing back at the matching acc.routine ops).

bind, gang, worker, vector, and seq clauses are tracked per-device-type via parallel ArrayAttr properties — for any non-none device type, at most one of gang/worker/vector/seq may be set, and similarly at most one for the none device type.

See external documentation.

    Implementation of upstream acc.routine — captures the clauses of an
    OpenACC routine directive together with the associated function name.
    The function keeps track of its corresponding routine declaration via
    the `acc.routine_info` discardable attribute (an `ArrayAttr` of
    `SymbolRefAttr` pointing back at the matching `acc.routine` ops).

    `bind`, `gang`, `worker`, `vector`, and `seq` clauses are tracked
    per-device-type via parallel `ArrayAttr` properties — for any non-`none`
    device type, at most one of `gang`/`worker`/`vector`/`seq` may be set,
    and similarly at most one for the `none` device type.
