llvm/lib/AsmParser/LLParser.cpp: 2 * pointless copy ?

[dcb314]

Static analyser cppcheck says:

llvm/lib/AsmParser/LLParser.cpp:5173:47: performance: Function parameter 'Bound' should be passed by const reference. [passedByValue]

Source code is

auto convToMetadata = [&](MDSignedOrMDField Bound) -> Metadata * {

llvm/lib/AsmParser/LLParser.cpp:5205:47: performance: Function parameter 'Bound' should be passed by const reference. [passedByValue]

Duplicate.
