MCSymbol *symbol = Ctx->getOrCreateSymbol("mySymbol");
machinecode.addOperand(MCSymbolRefExpr::create(symbol, MCSymbolRefExpr::VK_None, Ctx));
symbol->setVariableValue(MCConstantExpr::create(value, Ctx));This sets the value of the MCSymbol "symbol" to the constant expression "value". Package/Library: LLVM In conclusion, MCSymbol is a class in the LLVM package/library that is used to represent symbols in machine code output. It is used to create, reference, and set the value of symbols.
