- C99 features
The compiler makes some language features of C99
available:
As extensions to strict C90,
for example, //
-style comments.
As extensions to both Standard C++ and strict C90,
for example, restrict
pointers.
- Standard C extensions
The compiler supports numerous extensions to strict
C99, for example, function prototypes that override old-style nonprototype
definitions.
These extensions to Standard C are also available in C90.
- Standard C++ extensions
The compiler supports numerous extensions to strict
C++, for example, qualified names in the declaration of class members.
These extensions are not available in either Standard C or
C90.
- Standard C and Standard C++ extensions
The compiler supports some extensions specific to
strict C++ and strict C90, for example, anonymous classes, structures,
and unions.
- ARM-specific extensions
The compiler supports a range of extensions specific
to the ARM compiler, for example, instruction intrinsics and other
built-in functions.
