std::error_code orcError(OrcErrorCode ErrCode)
Definition: OrcError.cpp:84
This is an optimization pass for GlobalISel generic memory operations.
Definition: AddressRanges.h:18
OutputIt move(R &&Range, OutputIt Out)
Provide wrappers to std::move which take ranges instead of having to pass begin/end explicitly.
Definition: STLExtras.h:1849
Implement std::hash so that hash_code can be used in STL containers.
