Using the Inline and Embedded Assemblers of the ARM Compiler 7.46 Calling nonstatic member functions in embedded assembler You can use keywords beginning with __mcall and __vcall to call nonvirtual and virtual functions from __asm functions. There is no __mcall_is_static to detect static member functions because static member functions have different parameters (that is, no this), so call sites are likely to already be specific to calling a static member function. 7.46.1 See also Concepts • Compiler-supported keywords for calling class member functions in embedded assembler on page 7-47 • Calling a nonvirtual member function on page 7-54 • Calling a virtual member function on page 7-55.

Using the Inline and Embedded Assemblers of the ARM Compiler 7.47 Calling a nonvirtual member function Example 7-6 shows code that can be used to call a nonvirtual function in either a virtual or nonvirtual base: Example 7-6 Calling a nonvirtual function // rp contains a D* and we want to do the equivalent of rp->f() where f is a // nonvirtual function // all arguments other than the this pointer are already set up // assumes f does not return a struct if __mcall_is_in_vbase(D, f) LDR r12, [rp] // fetch vtable pointer LDR r0, [r12, #-__mcall_offsetof_vbase(D, f)] // fetch the vbase offset ADD r0, r0, rp // do this adjustment else ADD r0, rp, #__mcall_this_offset(D, f) endif BL __cpp(&D::f) // set up and adjust this // pointer for D* // call D::f 7.47.1 See also Concepts • Calling nonstatic member functions in embedded assembler on page 7-53.
