A @code{CALL_EXPR} whose value is ignored can also be a statement. No other C expressions can appear at statement level; a reference to a volatile object is converted into a @code{MODIFY_EXPR}. +In GIMPLE form, type of @code{MODIFY_EXPR} is not meaningful. Instead, use type +of LHS or RHS. There are also several varieties of complex statements. |
