- Common declarations and definitions for Standard C Library headers.
-
- This header consolidates definitions and declarations for compiler specific
- features in one place in order to assist in making the remainder of the
- library as compiler independent as possible.
-
- Certain macro and type definitions are required to be provided by several
- different headers. In order to avoid having multiple definitions, and the
- attendant risk of having the definitions get out of sync, they are defined in
- this header.
-
- Note that MdePkg/Include/Base.h is automatically included and will bring
- processor architecture specific definitions along with it.
-
- Throughout the library, the following macros are used instead of keywords so
- that the library can be easily tuned for different compilers.
- __inline Defined to the appropriate keyword or not defined.
- __func__ Defined to __FUNC__, __FUNCTION__, or NULL as appropriate.
- __restrict Defined to nothing for VC++ or to restrict for GCC and C99 compliant compilers.
-
- This file and its contents are inspired by the <sys/cdefs.h> files in Berkeley
- Unix. They have been re-implemented to be specific to the EFI environment.

- * checks, assuming you want to optimize for the no-error case.
- *
- * * Other than that, if you don't know the likelihood of a test
- * succeeding from empirical or other `hard' evidence, don't
- * make predictions.
- *
- * * These are meant to be used in places that are run `a lot'.
- * It is wasteful to make predictions in code that is run
- * seldomly (e.g. at subsystem initialization time) as the
- * basic block reordering that this affects can often generate
- * larger code.
