A fix has been applied to the ARM assembler’s expression parsing logic to address an uninitialized exp.X_op field. The initialization of the expressionS structure is now performed before the first return in the my_get_expression function. This ensures that all fields within the expression structure are properly initialized, preventing potential errors or undefined behavior during the parsing of ARM assembly expressions.
