Using the Inline and Embedded Assemblers of the ARM Compiler 7.38 Manual overload resolution in embedded assembler Example 7-4 shows the use of C++ casts to do overload resolution for nonvirtual function calls: Example 7-4 C++ casts void g(int); void g(long); struct T { int mf(int); int mf(int,int); }; __asm void f(T*, int, int) { BL __cpp(static_cast(&T::mf)) // calls T::mf(int, int) BL __cpp(static_cast(g)) // calls g(int) BX lr } 7.38.1 See also Concepts • Compiler support for embedded assembler on page 7-36.

Using the Inline and Embedded Assemblers of the ARM Compiler 7.39 __offsetof_base keyword for related base classes in embedded assembler The __offsetof_base keyword enables you to determine the offset from the beginning of an object to a base class sub-object within it: __offsetof_base(D, B) B must be an unambiguous, nonvirtual base class of D. Returns the offset from the beginning of a D object to the start of the B base subobject within it. The result might be zero. Example 7-5 shows the offset (in bytes) that must be added to a D* p to implement the equivalent of static_cast(p). Example 7-5 static_cast(p) __asm B* my_static_base_cast(D* /*p*/) // equivalent to: // return static_cast(p) { if __offsetof_base(D, B) 0 // optimize zero offset case ADD r0, r0, #__offsetof_base(D, B) endif BX lr } The __offsetof_base, __mcall_*, and _vcall_offsetof_vfunc keywords are converted into integer or logical constants in the assembler source. You can only use it in __asm functions, not in __cpp expressions. 7.39.1 See also Concepts • Restrictions on embedded assembly language functions in C and C++ code on page 7-40 • Compiler support for embedded assembler on page 7-36.
