areConsecutive() [1/2]

template<typename LoadOrStoreT >

areConsecutive() [2/2]

template<typename LoadOrStoreT >

static bool llvm::sandboxir::VecUtils::areConsecutive ( LoadOrStoreT *  I1, LoadOrStoreT *  I2, ScalarEvolution &  SE, const DataLayout &  DL  )

inlinestatic

\Returns true if I1 and I2 are load/stores accessing consecutive memory addresses.

getCommonScalarType()

static Type * llvm::sandboxir::VecUtils::getCommonScalarType ( ArrayRef< Value * >  Bndl )

inlinestatic

Similar to tryGetCommonScalarType() but will assert that there is a common type.

So this is faster in release builds as it won't iterate through the values.

getElementType()

static Type * llvm::sandboxir::VecUtils::getElementType ( Type *  Ty )

inlinestatic

Returns Ty if scalar or its element type if vector.

getLowest()

getNumElements()

static int llvm::sandboxir::VecUtils::getNumElements ( Type *  Ty )

inlinestatic

\Returns the number of elements in Ty.

That is the number of lanes if a fixed vector or 1 if scalar. ScalableVectors have unknown size and therefore are unsupported.

getNumLanes() [1/3]

static unsigned llvm::sandboxir::VecUtils::getNumLanes ( ArrayRef< Value * >  Bndl )

inlinestatic

\Returns the total number of lanes across all values in Bndl.

Definition at line 86 of file VecUtils.h.

References getNumLanes().

getNumLanes() [2/3]

static unsigned llvm::sandboxir::VecUtils::getNumLanes ( Type *  Ty )

inlinestatic

\Returns the number of vector lanes of Ty or 1 if not a vector.

NOTE: It asserts that Ty is a fixed vector type.

getNumLanes() [3/3]

static unsigned llvm::sandboxir::VecUtils::getNumLanes ( Value *  V )

inlinestatic

\Returns the expected vector lanes of V or 1 if not a vector.

NOTE: It asserts that V is a fixed vector.

Definition at line 81 of file VecUtils.h.

References llvm::sandboxir::Utils::getExpectedType(), and getNumLanes().

getWideType()

static Type * llvm::sandboxir::VecUtils::getWideType ( Type *  ElemTy, unsigned  NumElts  )

inlinestatic

\Returns <NumElts x ElemTy>.

It works for both scalar and vector ElemTy.

tryGetCommonScalarType()

static Type * llvm::sandboxir::VecUtils::tryGetCommonScalarType ( ArrayRef< Value * >  Bndl )

inlinestatic

If all values in Bndl are of the same scalar type then return it, otherwise return nullptr.
