Compiler defined compiler macros

[VedantParanjape]

Does pru-gcc have any kind of compiler defined macros, like when i pass -mmcu=am335x.pru0 or am335x.pru1, is there some way i could so something like this:

#ifdef __PRU0__
    #define HOSTINT (uint32_t) 1 << 30
#elif __PRU1__
    #define HOSTINT (uint32_t) 1 << 31
#else

$ pru-gcc -E -dM -mmcu=am335x.pru0 - </dev/null
#define __AM335X_PRU0__ 1

The mmcu option actually picks a per-core/SoC file. For the gory details see here: https://github.com/dinuxbg/gnuprumcu/blob/master/device-specs/am335x.pru0
