TFILLPAD_EXPAND¶

指令示意图¶

简介¶

填充/填充时允许目标大于源。

数学语义¶

除非另有说明, semantics are defined over the valid region and target-dependent behavior is marked as implementation-defined.

汇编语法¶

PTO-AS 形式：参见 PTO-AS Specification.

AS Level 1 (SSA)¶

%dst = pto.tfillpad_expand %src : !pto.tile<...> -> !pto.tile<...>

AS Level 2 (DPS)¶

pto.tfillpad_expand ins(%src : !pto.tile_buf<...>) outs(%dst : !pto.tile_buf<...>)

AS Level 1（SSA）¶

%dst = pto.tfillpad_expand %src : !pto.tile<...> -> !pto.tile<...>

AS Level 2（DPS）¶

pto.tfillpad_expand ins(%src : !pto.tile_buf<...>) outs(%dst : !pto.tile_buf<...>)

C++ 内建接口¶

声明于 include/pto/common/pto_instr.hpp:

template <typename DstTileData, typename SrcTileData, typename... WaitEvents>
PTO_INST RecordEvent TFILLPAD_EXPAND(DstTileData &dst, SrcTileData &src, WaitEvents &... events);

约束¶

Type/layout/location/shape legality is backend-dependent; treat implementation-specific notes as normative for that backend.
