-/* Source language
- *
- * The compiler is expected to define preprocessor symbols as follows:
- * __cplusplus when compiling in C++ mode.
- * __thumb when compiling to Thumb code.
- *
- * Some use is made of embedded assembly language, introduced by __asm.
- * This is described in ARM's toolchain documentation. Some edits may be
- * required for other compilers. The compiler should define one or more of:
- * __TARGET_ARCH_4T __TARGET_ARCH_4TXM __TARGET_ARCH_5T __TARGET_ARCH_5TXM
- * __TARGET_ARCH_5TE __TARGET_ARCH_6
- * so the correct assembly wrappers are generated for certain functions.
- *
- * __APCS_INTERWORK should be defined if ARM/Thumb interworking is required.
- *
- * For all the above symbols, if your compiler does not provide appropriate
- * definitions, add them here.
- *
- * Some source language extensions are also used.

-/* Library structure
- *
- * ARM's private make system contains an automated facility for compiling
- * source files multiple times to create multiple object files. The source
- * regions intended to constitute object file xxx.o are delimited by
- * #ifdef xxx_c / #endif directives. The exact preprocessor symbols used
- * for this conditionalisation are described in a comment at the start of
- * each file. When porting to a different system, compilations must be
- * performed with these preprocessor symbols appropriately defined
- * (or remove the conditionalisation).
- *
- * ARM declares (or redeclares) some routines as weak in order that
- * references to them are weak, so that the static linker will not load
- * unwanted code. This is achieved by decorating routine declarations
- * with appropriate language extensions. Note that compilers supporting
- * similar features but via a different syntax may require edits to
- * the library source.
- *
- * Define those decorations here (define as empty if not required):

- * #ifdef ARM_EXCEPTIONS_ENABLED / #endif. Define ARM_EXCEPTIONS_ENABLED
- * by some means here if you want a usable library:
