◆ cloneSymbol()

MCSymbol * MCContext::cloneSymbol ( MCSymbol & Sym)

Existing references to the original symbol remain unchanged, and the original symbol is not emitted to the symbol table.

bool AlwaysEmit = false )

Get or create a symbol for a basic block.

For non-always-emit symbols, this behaves like createTempSymbol, except that it uses the PrivateLabelPrefix instead of the InternalSymbolPrefix. When AlwaysEmit is true, behaves like getOrCreateSymbol, prefixed with PrivateLabelPrefix.
