12.1 EDK - Are there target-specific definitions for the MicroBlaze and PowerPC processors?

描述

Are there target-specific definitions for the MicroBlaze and PowerPC processors in the GNU compiler?

解决方案

There are target-specific #defines built into mb-gcc and powerpc-eabi-gcc compilers. Following is an example piece of code to demonstrate usage for MicroBlaze and PowerPC, respectively:

#if defined(__PPC__)

if (hdr->ih_arch != IH_CPU_PPC)

#elif defined(__MICROBLAZE__)

if (hdr->ih_arch != IH_CPU_MICROBLAZE)

#else

# error Unknown CPU type

#endif
