Chapter 16 C++ Compiler

The compiler does not allow expressions in inline assembly statements that depend on template parameters. See

Listing 16-7 on page 303 .

Listing 16-7. Assembly statements cannot depend on template arguments

template <typename T> void asm_tmpl()

{

asm { move #sizeof(T), D0 ); // ERROR: Not supported.

}

The compiler also supports the address of template-id rules. See

Listing 16-8 on page

303 .

Listing 16-8. Address of Template-id Supported

template <typename T> void funcA(T) {} template <typename T> void funcB(T) {}

...

funcA{ &funcB<int> ); // now accepted

16.3 Implementation-Defined Behavior

Annex A of the ISO/IEC 14882:2003 C++ Standard lists compiler behaviors that are beyond the scope of the standard, but which must be documented for a compiler implementation. This annex also lists minimum guidelines for these behaviors, although a conforming compiler is not required to meet these minimums.

The CodeWarrior C++ compiler has these implementation quantities listed in

Table 16-2

, based on the ISO/IEC 14882:2003 C++ Standard, Annex A.

NOTE

The term unlimited in

Table 16-2

means that a behavior is limited only by the processing speed or memory capacity of the computer on which the CodeWarrior C++ compiler is running.

Table 16-2. Implementation Quantities for C/C++ Compiler (ISO/IEC 14882:2003 C++, §A)

Behavior

Nesting levels of compound statements, iteration control structures, and selection control structures

Nesting levels of conditional inclusion

Pointer, array, and function declarators

(in any combination) modifying an arithmetic, structure, union, or incomplete type in a declaration

Nesting levels of parenthesized expressions within a full expression
