#define LLVM_DUMP_METHOD

Mark debug helper function definitions like dump() that should not be stripped from debug builds.

#define LLVM_ABI_FOR_TEST

This file implements a set that has insertion order iteration characteristics.

This pass exposes codegen information to IR-level passes.

ArrayRef - Represent a constant reference to an array (0 or more elements consecutively in memory),...

A vector that has set insertion semantics.

This is a 'vector' (really, a variable-sized array), optimized for the case when the array is small.

This pass provides access to the codegen interfaces that are needed for IR-level transformations.

TargetCostKind

The kind of cost model.

@ TCK_RecipThroughput

Reciprocal throughput.

A range adaptor for a pair of iterators.

This class implements an extremely fast bulk output stream that can only output to a stream.

An ID for a registered callback.

A sandboxir::User with operands, opcode and linked with previous/next instructions in an instruction ...

A helper client-attorney class for unit tests.

Convenience function for iterating over sub-ranges.
