#ifndef _CORECRYPTO_CC_CONFIG_H_
#define _CORECRYPTO_CC_CONFIG_H_
/* A word about configuration macros:
Conditional configuration macros specific to corecrypto should be named CORECRYPTO_xxx
or CCxx_yyy and be defined to be either 0 or 1 in this file. You can add an
#ifndef #error construct at the end of this file to make sure it's always defined.
They should always be tested using the #if directive, never the #ifdef directive.
No other conditional macros shall ever be used (except in this file)
Configuration Macros that are defined outside of corecrypto (eg: KERNEL, DEBUG, ...)
shall only be used in this file to define CCxxx macros.
External macros should be assumed to be either undefined, defined with no value,
or defined as true or false. We shall strive to build with -Wundef whenever possible,
so the following construct should be used to test external macros in this file:
#if defined(DEBUG) && (DEBUG)
#define CORECRYPTO_DEBUG 1
#else
#define CORECRYPTO_DEBUG 0
#endif
It is acceptable to define a conditional CC_xxxx macro in an implementation file,
to be used only in this file.
The current code is not guaranteed to follow those rules, but should be fixed to.
Corecrypto requires GNU and C99 compatibility.
Typically enabled by passing --gnu --c99 to the compiler (eg. armcc)
