Functions | |
| static Type | isElementTypeInconsistent (Value addr, Type expectedType) |
| Checks that a pointer value has a pointee type hint consistent with the expected type. More... | |
| static std::optional< uint64_t > | gepToByteOffset (DataLayout &layout, GEPOp gep) |
| Returns the amount of bytes the provided GEP elements will offset the pointer by. More... | |
| static LogicalResult | findIndicesForOffset (DataLayout &layout, Type base, uint64_t offset, SmallVectorImpl< GEPArg > &equivalentIndicesOut) |
Fills in equivalentIndicesOut with GEP indices that would be equivalent to offsetting a pointer by offset bytes, assuming the GEP has base as base type. More... | |
| static FailureOr< Type > | getRequiredConsistentGEPType (GEPOp gep) |
| Returns the consistent type for the GEP if the GEP is not type-consistent. More... | |
| static FailureOr< DestructurableTypeRange > | getWrittenToFields (const DataLayout &dataLayout, DestructurableTypeInterface destructurableType, unsigned storeSize, unsigned storeOffset) |
Returns the list of elements of destructurableType that are written to by a store operation writing storeSize bytes at storeOffset. More... | |
| static void | splitVectorStore (const DataLayout &dataLayout, Location loc, RewriterBase &rewriter, Value address, TypedValue< VectorType > value, unsigned storeOffset) |
Splits a store of the vector value into address at storeOffset into multiple stores of each element with the goal of each generated store becoming type-consistent through subsequent pattern applications. More... | |
| static void | splitIntegerStore (const DataLayout &dataLayout, Location loc, RewriterBase &rewriter, Value address, Value value, unsigned storeSize, unsigned storeOffset, DestructurableTypeRange writtenToFields) |
Splits a store of the integer value into address at storeOffset into multiple stores to each 'writtenToFields', making each store operation type-consistent. More... | |

Returns the consistent type for the GEP if the GEP is not type-consistent.
Returns failure if the GEP is already consistent.

static |
Returns the list of elements of destructurableType that are written to by a store operation writing storeSize bytes at storeOffset.
storeOffset is required to cleanly point to an immediate element within the type. If the write operation were to write to any padding, write beyond the aggregate or partially write to a non-aggregate, failure is returned.

Checks that a pointer value has a pointee type hint consistent with the expected type.
Returns the type it actually hints to if it differs, or nullptr if the type is consistent or impossible to analyze.
