I want to migrate my projects from Keil Arm Compiler V5 to V6.
According to this tutorial the language extensions need to be revised in the code.
https://www.keil.com/appnotes/files/apnt_298.pdf
What will be the recommended preprocessor definition to identfy the compiler?
Example:
#if defined(__ARM_COMPILER_V5__)
#define __WEAK__ __weak
#define __PACKED__ __packed
#endif
#if defined(__ARM_COMPILER_V6__)
#define __WEAK__ __attribute__((weak))
#define __PACKED__ __attribute__((packed))
Refer to:
"Language extension compatibility: keywords"

Thank you for the quick reply.
I have already found the listed documents and links. However, the directives listed there did not seem to me to be goal-oriented or too complex. The __CC_ARM and __GNUC__ directives have not been found to be reliable. I'll try __ARMCC_VERSION then.
