Compiler error C2614 'class': illegal member initialization: 'identifier' is not a base or member Compiler error C2615 'offsetof' cannot be applied to non-class type 'type' Compiler error C2616 'conversion': cannot implicitly convert a non-lvalue 'type1' to a 'type2' that is not const...
We identified a bug in class data members' internal representation when a type name is also overloaded as a data member's name. This bug caused inconsistencies in aggregate initialization and member initialization order. The generated initialization code is now correct. However, this change can ...
With —xcheck=init_local, the compiler initializes local variable declared without an initializer to a pre-defined value as shown in the table below. (Note that these values may change and should not be relied upon.) Basic Types Table B-20 init_local Initialization for Basic Types Type Initi...
It is more efficient to use a global variable than to pass a parameter to a function. This eliminates the need to push the parameter onto the stack before the function call and pop it back off once the function is completed. In fact, the most efficient implementation of any subroutine woul...

(x86) Does not convert the value of a floating-point expression or function to the type on the left-hand side of an assignment, when that expression or function is assigned to a variable or is cast to a shorter floating-point type; rather, it leaves the value in a register. See also...
