class ScalarizationResult

Declaration

class ScalarizationResult { /* full declaration omitted */ };

Description

Helper class to indicate whether a vector index can be safely scalarized and if a freeze needs to be inserted.

Declared at: llvm/lib/Transforms/Vectorize/VectorCombine.cpp:826

Parameters

const ScalarizationResult& Other

¶void discard()

Description

Reset the state of Unsafe and clear ToFreze if set.

Declared at: llvm/lib/Transforms/Vectorize/VectorCombine.cpp:846

¶void freeze(IRBuilder<>& Builder,
            llvm::Instruction& UserI)

Description

Freeze the ToFreeze and update the use in \p User to use it.

Declared at: llvm/lib/Transforms/Vectorize/VectorCombine.cpp:852

Parameters

IRBuilder<>& Builder

llvm::Instruction& UserI

¶bool isSafe() const

Description

Returns true if the index can be scalarize without requiring a freeze.

Declared at: llvm/lib/Transforms/Vectorize/VectorCombine.cpp:838

¶bool isSafeWithFreeze() const

Description

Returns true if the index can be scalarize, but requires inserting a freeze.

Declared at: llvm/lib/Transforms/Vectorize/VectorCombine.cpp:843

¶bool isUnsafe() const

Description

Returns true if the index cannot be scalarized.
